Introduction
While the rise of technology has allowed U.S.
businesses to market their products and services
across the globe, the expansion of global
commerce has allowed developing countries
to quickly enter and penetrate the global
market place. U.S. businesses are
realizing that they are now competing
with governments and businesses
around the world that often have
lower labor rates, cheaper raw
materials and lower energy costs.
To remain competitive in the
market place, U.S. companies are
feeling the pressure to lower their
overall operating costs.
With rising energy costs and a
volatile energy future, businesses
are finding that they can better
meet their financial goals by
controlling their total operating
costs through energy conservation
measures which can immediately
and substantially impact their bottom
line performance. In most businesses,
energy required to operate lighting
equipment is a primary constituent of
their overall energy bill, therefore some
type of new, energy-efficient, lighting
equipment is often a solid investment to
improve your company’s bottom line. Renovating
the lighting system in your industrial or retail
space can result in substantial energy savings - even
using conservative numbers, paybacks can be realized
in as little as ½ to 3 years. To provide additional incentives
for energy conservation, federal programs such as EPAct, as
well as utility rebates, further enhance the financial package that
most CEO’s and CFO’s review prior to final approval of a project.
Energy Savings and
Quality go Hand in Hand
Example
While the importance of incorporating
‘Green’ and ‘Sustainable’ operations into
every day business has increased in the
United States over the last several years,
Holophane Lighting has promoted this
concept for more than 100 years. Since
1898, Holophane has manufactured
products using borosilicate glass that
virtually never wear out. Our history and
experience conclusively show that using
glass reduces land fill volume and the
need to mine additional natural resources
and eliminates the need to use energy to
produce a new item, thereby reducing
greenhouse emissions. Holophane’s
permanence is ‘Green’.
manufacturing is looking to improve its bottom line by cutting
operating costs through an energy savings program. It determines that
one of the quickest ways to realize a payback on their investment would be
to undertake a lighting renovation project. After a quick visit with an
energy savings guru, a new lighting system was installed for $38,000 cutting their lighting bill
in half to approximately $20,000/year yielding a payback in less than 2 years – a seemingly
sound investment...
ABC
...A few months after installation,
the plant manager noticed a small decrease in productivity. After a thorough review of
the facility, the plant manager soon realized that some areas of the facility were not
as bright as they used to be and other areas were far worse than previously illuminated.
An overall productivity loss of 1% was incurred when the company chose to install their
new ‘energy-saving’ lighting system.
While seemingly small at only 7.2 minutes per day (less than 1 minute per hour),
the plant manager conducted a quick impact analysis and ascertained the following:
ABC manufacturing employs 100 employees who each work 40 hours/week to make 8,000
widgets per month. If each widget sells for an average of $500 then that company will
make $48,000,000 in revenue annually. The 1% loss in productivity equates to a revenue
loss of $480,000/year. In short, every dollar of energy saved from their new ‘energysaving’ lighting system winds up costing the company $13 in lost revenue.
After bringing this to the attention of senior staff, the company then decided to
bring in a lighting expert from Holophane.
Holophane has over 100 years of
experience in providing unique and
innovative solutions for the lighting
industry that provide our customers
with the lowest total cost of ownership.
Holophane provides both a “Quality”
lighting solution and an “Energy-Saving”
solution to ensure that your company
improves its bottom line through
increased productivity and lower operating
costs. Unfortunately, many companies
are only concerned with selling you a bill
of goods guised as an ‘energy saving
product’ with no regard to the ‘quality’ of
the lighting solution, or life cycle costing.
The local Holophane sales representative, who had been extensively trained in all facets
of lighting design, quickly determined that the initial design did not take into account
the effect that heat and airborne grease from their daily manufacturing operations
would have on their overall light output.
A ‘Quality’ lighting solution that realized the same 50% energy savings was installed
and ABC manufacturing now realizes a 1.5% improvement in productivity over their old
lighting system. Instead of losing 480,000/yr in revenue, the company now realizes a
$720,000/yr revenue gain + the $20,000 of energy savings every year!
Almost any lighting solution can save you energy, but a ‘Quality’ lighting solution can help
improve your company’s bottom line through increased sales or productivity and energy savings.
In industrial facilities, a new lighting system may create a more productive work environment.
Due to the high cost of operations
coming from salaries and benefits, a
1 percent increase in productivity can
completely pay for even the most
expensive lighting systems. In retail
environments, an updated lighting
system can be easily justified
through the increased revenue from
additional customers attracted to the
‘newly refreshed store’. Delaying
your lighting renovation project can
actually cost your company revenue.

Lighting Renovation Methods
When considering updating a facility’s lighting system, there are
basically three methods to consider, each with varying degrees
of cost, complexity and potential energy savings:
Retrofitting: When this method is used, lighting components
are examined for efficiency and then replaced with components
that improve the efficiency of the installation. Lamps and ballasts
are usually replaced while reflectors, lenses or louvers may be
cleaned or replaced depending upon condition and budgetary and
time constraints. Sometimes simple changes in the control system,
such as adding motion sensors, are a possibility.
8
HOLOPHANE®
| Lighting Renovation Guide
Replacement: This method involves replacing existing luminaires
having older technology with a completely new luminaire having
updated energy efficient technology on a one-for-one basis.
Luminaires using HID probe start lamps or fluorescent T12 lamps
are replaced with luminaires using HID pulse start lamps or
T8/T5HO fluorescent lamps and luminaires using magnetic ballasts
may be replaced with luminaires having electronic ballasts.
Additionally, the appearance of the luminaire may change drastically
due to new shapes, reflector materials and/or body styles.
Hybrids of the previously mentioned methodologies are an
alternative, but choosing between these three methods is critical
because the results are considerably different.
Relighting: This method requires a more in-depth analysis
not only of the lighting components but also of many other
issues affecting the performance of the lighting systems such
as circuit sizing, appearance, interior design, traffic control,
visibility, psychological responses, regulatory compliance, user
expectations, flexibility requirements, day-lighting contribution
and control systems. Old luminaires and wiring/conduit are
removed; new lighting systems are installed, typically with
new control systems and in different locations than the
existing system to maximize energy savings.

Lighting Renovation Guide
A Retrofitting project can usually be performed
with minimal disruption. But other than a subtle
“freshening” of the space, a lighting retrofit
seldom changes the character of the space. The
result is often seen as converting an ‘inefficient
and dated lighting system’ to an ‘efficient and
dated lighting system’. Retrofitting is relatively
easy to calculate cost and payback, and it is easy
to manage. Retrofitting also tends to cost less
than Replacing or Relighting, but Retrofitting
is typically not viewed as a capital improvement
and therefore treated more like a mechanical
repair. For buildings that have a modest mission
or don’t have to compete in the marketplace,
like government buildings, a retrofit may be an
alternative.
A one-for-one Replacement project can often be
performed with minimal disruption to operations,
but the space often looks substantially different
due to the change in luminaire appearance and
performance. A Replacement project normally
costs more than a Retrofit project, but is often less
complex and time consuming to perform.
Replacement projects are typically considered a capital
improvement and therefore often qualify for utility
rebates and other financial incentives. While the cost
of moving or adding circuits is usually eliminated, the
final result is typically better than a Retrofit, but is often
not the optimal solution in regards to performance
and energy savings.
10
HOLOPHANE®
| Lighting Renovation Guide
While Retrofitting was popular in the 90’s when
energy costs were relatively low, rebates and tax
incentives coupled with today’s higher energy
costs make one-for-one Replacement and
Relighting projects the preferred methodologies.
There’s a myriad of opportunities to cut money
out of a project that is viewed as too costly. Using
lower grade luminaires, compromising on required
light levels, hiring unlicensed labor, using cheaper
materials and overlooking long term gains are all
ways to recoup initial costs. However, there is
nothing more costly to your business than a
project that causes disruption to your operations.
Holophane Solutions yield the lowest total cost of
ownership and minimize this disruption over the
life of the system. More importantly, your
company can realize incremental gains in revenue
through increased productivity or new customers
by relighting your facility!
HOLOPHANE®
| Lighting Renovation Guide
Lighting Renovation Methods
A Relighting project often requires major work that can
be disruptive to business and building operations, but
the result is typically greater energy savings through a
more efficient lighting system when compared to
Retrofitting or Replacement methods. Additionally, the
new lighting system is often perceived as contemporary
and thus more appealing. Relighting requires more time
and initial costs and is usually considered a capital
improvement. Although more costly, it may prove to
provide the lowest total cost of ownership in the long
run. Incentive programs like EPAct and/or rebates from
the local utility are excellent ways to defray the higher
initial costs. Relighting is a thorough approach that
considers factors that affect the quality of light as well
as initial and operating costs. Because Relighting is not
a clear-cut process of simple engineering, considerations
and results may vary, but the final decision almost always
hinges upon an economic analysis.
11
Lighting Renovation Guide
Environmental Considerations
The lighting designer must take into account a variety of
environmental factors including user needs and preferences,
safety regulations, maintenance requirements and energy
consumption. To help you navigate through the multiple lighting
possibilities, these factors are discussed in greater detail below.
Matching existing light levels, when relighting a facility, is a common mistake. Most retail and
industrial facilities use lighting technology that depreciates over time, therefore the designed
illumination level should be focused on what light level is required at some predetermined
point in the future. If your goal is to merely equal current light levels with a new lighting
system, you may be missing opportunities to capture incremental savings or improve productivity.
Analysis of the Space
An important aspect of lighting design is a detailed analysis of
the environment. Functional elements that impact lighting
design and affect the overall light delivered to the task include
ceiling height, room surface finishes, work plane height,
windows, skylights or other fenestrations, equipment size
and shape, the geometry of the space, flexibility requirements,
removal of hazardous wastes and existing wiring conditions.
Environmental conditions, including dust and dirt, presence of
chemicals, airborne grease, moisture, insects, temperature
extremes, vibration and incidental abuse have a significant
effect on the selection of the proper luminaire. Food processing
areas, for example, sometimes require special options for lighting
fixtures, whereas retail lighting is often dependent upon the
type of product or service being sold, the size and location of
the store, function performed within specific areas of the store,
colors and textures of products, method of display (racks,
gondolas or counters) and the overall merchandising strategy.
Exterior spaces also require evaluation. Proper lighting can
invite and direct potential customers to enter the store, enhance
the architectural features of a building at night and provide
safety and security. General exterior considerations include the
type and color of exterior building materials, type and location
of plants used in the landscape, and the placement of exterior
lighting so it does not interfere with driveways or produce glare.
The design considerations must also balance with the company’s
brand image.
12
HOLOPHANE®
| Lighting Renovation Guide
Industrial environments often involve grease, oil, relatively
high temperatures, smoke, dust, or steam which can
decrease a luminaire’s efficiency. Using the latest in optical,
electronic, and thermal management technologies,
Holophane’s luminaires are designed specifically for a
variety of environments to create safe, and sanitary
environments while providing effective and energy
efficient solutions for our customers over the long haul.
Retail environments require luminaires that are not only
energy efficient but also aesthetically pleasing. Attracting
and guiding customers through the store while aiding the
customer in merchandise evaluation through proper color
rendering, glare control and vertical surface illumination
are primary concerns. Furthermore, lighting systems for
retail applications must be flexible and easily controlled
through various means such as dimming or dual circuits.
Outdoor environments require luminaires that meet certain
aesthetic requirements while offering exceptional performance.
Both optical performance to optimize pole spacings and
maximize safety and security and luminaire performance to
insure low maintenance costs and down time.
HOLOPHANE®

Lighting Renovation Guide
Flexibility and Control Requirements
Changes in the work space often require general renovations.
If the location of product displays, assembly lines or storage
racks change, the lighting must be re-evaluated. In retail stores
and certain industrial applications, where task locations
change relatively frequently, the use of flexible wiring
systems may offer significant advantages. While initial
luminaire installation time will be slightly reduced,
time and cost savings when relocating luminaires in the
future becomes significant when utilizing our Holoflex®
modular wiring system.
In some instances, activities within the same space may
change throughout the day. Manufacturing activities may
be conducted during one shift, maintenance of equipment
performed during another shift, and security may be necessary
during the non-productive periods. Each activity may require
different illumination levels, therefore
manual or automatic controls such as
bi-level switching, on/off switching
and/or dimming controls may be
beneficial. In multi-location facilities, building automation
systems are available to seamlessly integrate all aspects of
lighting control including low-voltage switching, dimming,
occupancy sensing and Daylight Harvesting™ systems to
maximize corporate energy savings. Holophane offers
scalable and flexible control systems from occupancy sensors
for the simplest of applications to customized functionality in
distributed controls for large complexes that may be spread
across the globe.
Safety Requirements
Light levels must be sufficient to minimize on-the-job injuries
which occur more frequently in industrial settings. Lighting
must also ensure a safe environment during an emergency.
In the event of a fire or power outage, emergency lighting
and exit signs must enable occupants to identify a clear path
of egress, even through smoke. Holophane offers Emergency
and Exit lighting even for hazardous locations.
14
HOLOPHANE®
| Lighting Renovation Guide
Maintenance requirements can be an important consideration when
choosing a lighting system. A lighting system that requires minimal
maintenance costs allows the maintenance team to concentrate their
efforts on tasks such as keeping machines and people productive;
tasks that directly effect revenue generation. In many industrial or
big box retail applications, luminaires are mounted at high elevations,
directly over machinery, tall racks or in locations where special
equipment is required to access the luminaire.
While some fluorescent lamps may have longer life than traditional
HID lamps, most fluorescent high bay lighting systems will require 2
to 4 times as many lamps and ballasts per fixture as an HID lighting
system to maintain equivalent light output. Furthermore, HID ballasts
often have a rated life that is 2 to 3 times the life of a fluorescent
ballast. Selecting luminaires with multiple types of lamps and ballasts
may cause issues with the maintenance department who now has to
inventory more components. However, in some cases this may be
best to achieve your overall lighting objectives and greatest energy
savings. Holophane offers a variety of fluorescent and HID luminaires
that incorporate maintenance savings features into its products.
Energy Requirements
In light of sweeping energy conservation measures, the Energy Policy
Act (EPAct) requires all states to meet minimum energy requirements
as specified in the ASHRAE/IESNA Standard 90.1 code. Standard 90.1
establishes watts-per-square-foot criteria for various types of applications.
Lighting is one of the leading energy constituents and can have a
substantial impact on overall operating costs. Design criteria should
evaluate the local energy rate, all appropriate light loss factors, lighting
usage requirements throughout the day, and the availability of energy
saving technologies. In most cases, using Holophane luminaires will
result in a significant energy reduction through either fewer luminaires
or lower wattage while maintaining the designed illumination level.
See HL-2242, Holophane’s EPAct brochure for more information on the
Energy Policy Act of 2005.

Maintenance Requirements

Lighting Renovation Guide
Regulatory Compliance
Along with energy requirements, other factors to be considered
are the requirements from the Americans with Disabilities Act
which provides guidelines and
specifications for barrier-free
environments. Other regulatory
agencies include but are not limited
to NFPA, NEC, UL, OSHA, USDA,
NSF, NEMA, ANSI/IESNA, and the
IEC each with their own specific
rules and regulations that vary by application type. Your local
Holophane sales representative can help you determine which
regulations are appropriate for your particular application.
Cost Considerations
The total cost of ownership of a lighting system can be broken down
into three categories:
1) Installation costs - luminaire, wiring/conduit, and labor
2) Maintenance - ballast replacement, lamp replacement,
cleaning, and labor
3) Operating - energy consumption
Of these three categories, operating costs (energy consumption)
consists of about 80% of the total cost over the life of a lighting
system. Incremental costs in purchasing energy-saving components are
paid back quickly with the operating savings. Premium design and
materials selection may increase initial capital costs, but offer significant
advantages such as increased light levels, superior color rendition and
consistency, better uniformity, less glare, less maintenance, and lower
operating costs.
It is also important to consider the financial benefits that result from
high quality lighting: improved productivity, new customer acquisition,
lower rejection rates, customer retention, better quality control, and
increased customer satisfaction.
16
HOLOPHANE®

Environmental Considerations
Thermal Factor
Unlike HID lamps, fluorescent light sources are sensitive to
temperature extremes. Optimum light output for most fluorescent
lamps occurs when the air temperature surrounding the lamp is
25°C (35°C for T5 and T5HO lamps). Any temperature above or
below optimum reduces light output. In general, the higher the
luminaire mounting height is, the hotter the operating temperature
which is especially true in unconditioned spaces. These two thermal
factors are often disregarded in lighting design calculations and
can prove to have a significant difference between designed light
levels and actual light levels.
Temperature also has a tremendous effect on the life expectancy of
a ballast and its related components. Therefore, it is important not
to exceed the maximum ambient rating of the fixture. Operating
a fixture in environments that are cooler than its rated ambient
temperature will greatly increase ballast life. It is generally accepted
that for every 10° C below the fixture’s rated ambient temperature
the fixture is operated, the life of the ballast and capacitor doubles.
Holophane manufactures several luminaires incorporating thermal
management of the lamp and/or the ballast into their design.
Your local Holophane sales representative can help you determine
the proper thermal factor and the appropriate luminaire for your
application in your design analysis.

Lighting Renovation Guide
Illumination Considerations
When choosing a new lighting system, it is critical that certain
considerations are made. Failure to make these considerations
may determine whether your lighting renovation is a long term
success or not. How much maintained light is needed, why do I
need to account for light loss factors, what is uniformity and
many other careful considerations such as these will insure a
successful project.
Illuminance Levels
Illuminance is defined as the amount of light (called lumens)
reaching a surface and is measured in “footcandles” or
lumens per square foot. The metric equivalent is measured
in “lux” or lumens per square meter. The appropriate
illuminance for a space depends upon how the space is
being used in addition to the age of the workers (older eyes
require more light), the speed and accuracy requirements of
the task, the task contrast, and whether errors affect health
and safety.
Recommended lighting levels are usually derived from the
IESNA Lighting Handbook, however some regulatory agencies,
worker’s unions or OSHA may require more stringent
illumination levels. For example the USDA strictly regulates
the lighting requirements within the Food Processing industry.
Many factors have an impact on proper light levels, including
age, speed, accuracy, contrast, glare, flicker, distribution and
others. The influence of these factors may raise or lower the
desired light levels. For detailed information regarding these
and other related issues, consult your local Holophane factory
sales representative. Holophane’s sales consultants are lighting
experts - they go through extensive and continual training so
they can inform our customers of the latest technologies and
the best solution for their lighting requirements.
18
HOLOPHANE®
| Lighting Renovation Guide
Light Loss Factors
When performing lighting calculations, many factors can cause the
actual illuminance to vary from the calculated illuminance, It is
important to determine what your “maintained” light levels should be
initially and plan accordingly to reach that goal. For example, incorrect
surface reflectance’s, not accounting for large machinery or other
obstacles that block or reflect light and/or incomplete or inaccurate
light loss factors (LLF) can all affect your maintained or actual light
levels. Light Loss Factors are used to adjust lighting calculations from
a controlled laboratory environment to actual field conditions and/or
from an initial installation condition to a maintained predetermined
time frame condition. Total LLF takes into account that lighting
fixtures will get dirty over time, that lumen output of certain lamp
types are temperature dependent, that lamps will age causing the
lumen output to decrease over time and that ballast operation plays
a factor in lumen output. At a minimum, the following Light Loss
Factors must be taken into account:
• Luminaire Dirt Depreciation (LDD) – simply put, the
accumulation of dirt on luminaires results in a loss of light
output. The amount of dirt depreciation or light loss, is
dependent upon the luminaire construction, luminaire
materials and surrounding atmospheric conditions.
• Lamp Lumen Depreciation (LLD) – most lamps yield
continuously lower lumen output over their operating lives.
LLD is calculated by dividing mean lumens by initial lumens.
The amount of lumen depreciation is dependent upon the
lamp type, lamp wattage, number of starts and burn hours.
These lamp lumen depreciation values are readily available
from your lamp manufacturer and must be taken into
account when completing any lighting design.
• Thermal Factor (TF) – discussed on page 17 of this
brochure.
• Holophane has always utilized glass reflectors instead of
acrylic or aluminum reflectors. Unlike acrylic or aluminum,
glass is an inert material that resists taking on the
electrostatic charges that attract dirt and dust particles.
• With the heat generated by the lamp,
a constant flow of hot air creates a
“venturi effect” that minimizes dirt
buildup. This simple design concept
insures that LDD is minimized regardless
of the atmosphere it is in.
• Unlike other materials, glass can be cleaned and brought
back to 100% efficiency throughout the life of the optic
allowing it to transcend time.
• Ballast Factor (BF) – ballasts are used to convert line
voltage to lamp voltage and to regulate the current for lamp
start up and for lamp running. Holophane designs and
manufactures it’s own HID ballasts for a ballast factor of 1.0.
This means that each lamp is operated at full wattage. A
ballast factor of anything less than 1.0 means that the lamp
will not receive the intended wattage and will, therefore,
not generate the lumens intended thus reducing light
output. It is critical to know the ballast factor of the
fixture being used in your design so that you can accurately
calculate the number of fixtures needed to meet your
footcandle requirements.
Don’t be tricked into believing that the light levels that you see in
a new installation will be the light levels over the long haul.
Holophane designs their luminaires to maximize lumen output
when all light loss factors are considered. This results in fewer
fixtures and lower operating costs to receive the maintained light
levels that the end user requires.

Lighting Renovation Guide
Uniformity
For most industrial facilities, lighting uniformity is essential for good
visibility, however certain tasks or areas may require greater light
levels. Light pattern striations (non-uniform lighting) in the work
space can be distracting or confusing depending upon the task
being performed. Work surface illuminances that are 1-1/2 to 3
times greater than the surrounding areas assist in directing
occupant’s attention to the task, however greater luminance ratios
must be avoided to minimize visual fatigue. It is potentially a waste
of energy to maintain uniformity between adjacent areas that have
significantly different visibility and illumination requirements such as
storage racks next to an inspection area. In these instances, the
designer will need to apply the appropriate illumination to each
area, taking care not to exceed the recommended maximum
luminance ratios. To accomplish this, use luminaires of different
wattages, change the quantity and spacing of luminaires in those
areas or use task lighting.
Competitive
Improved uniformity
and reduced fixtures
For retail facilities uniformity may or may not be desired as previously
described in the Lighting Techniques section. In general, as the
product offering becomes more specialized (e.g. jewelry store)
and/or the square footage becomes smaller, the less ambient lighting
the store will typically have and the more accent lighting the store
will incorporate.
Many factors contribute to uniform lighting, including direct
illumination that shines downward from a luminaire and indirect
or ‘bounce’ light that reflects off the ceiling and other surfaces.
Holophane optical systems control the light so it reaches all
areas within a space without spilling over into other areas where
illumination is not desired.
ISD SuperGlass
Contrast
To be readily visible, each detail of a visual task must differ in luminance
or color from its background. Visibility is at a maximum when contrast
of an object with its background is very high. For example, dark
blue lettering on a yellow background exhibits high contrast and is
very easy to read.
HIGH CONTRAST
LOW CONTRAST
Desirable
Undesirable
However, light blue lettering on a dark green background is
considered low or poor contrast and is very difficult to decipher.
Whenever possible, task contrast should be made as high as
possible. Higher illuminance through supplemental lighting may
help compensate for poor contrast.
20
HOLOPHANE®
| Lighting Renovation Guide
In order to maintain good uniformity in a space, the
manufacturer’s published spacing criterion (SC) for a given
fixture must be known. If you multiply the spacing criterion
by the distance from the bottom of the fixture to the work
plane, you arrive at the maximum recommended fixture
spacing. Fixtures with low SC have more of a downward
throw and need to be spaced closer together to maintain
uniformity, and fixtures with higher SC have a more widespread distribution and can be spaced further apart. Spacing
criteria are based on providing uniform illumination and are
not a means of defining illuminance levels. This then becomes
the engineering tradeoff – light level vs uniformity. Two
luminaires having the same total lumen output, but different
spacing criterion may provide radically different light levels
EVEN if the spacing of the two systems is identical (which is
often the case in a 1-for-1 relighting application).
Distribution
Human beings often look straight ahead at a vertical
plane rather than down toward a horizontal plane so the
illuminance on a vertical plane is a critical element. Many
tasks such as shopping, machining, driving forklifts, reading
gauges and stocking shelves are located in the vertical
plane. To light the vertical plane, pay close attention to
fixture selection and fixture placement. In open areas,
fixtures with wide distributions may be required in addition
to supplemental task lighting to appropriately light the
vertical plane and overcome obstructions. In tall aisles,
such as those found in factory outlets or warehouses,
luminaires with narrow distributions may be required in
order to provide appropriate vertical light levels at eye level.
Illumination Considerations
Spacing Criteria
Shadows
Large machinery and/or tall racks may obstruct light and cause
shadows unless good lighting techniques are applied. Harsh
shadows are not desirable and can be avoided by providing
illumination from many different fixtures or from large diffusing
luminaires. However, soft shadows that are less pronounced can
accent the depth and form of objects. Clearly defined shadows
often aid in the visibility of engraved polished surfaces, some types
of bench work and certain textile inspections. Supplementary
directional lighting combined with diffused general lighting from
several fixtures can help achieve this effect.

Color Rendering
The use of color in retail stores or industrial plants is not
new, yet in today’s world of colored lighting and colored
materials, having the ability to determine the exact color
of an object may be more important in some areas than in
others. Color is a wonderful tool used to attract customers
to specific products, sort various grades of product,
emphasize brand image or locate items faster within a
warehouse.
Color rendering is the ability of a light source to represent
the true colors of an object. The closer the color rendering
index (CRI) is to 100, the more natural the colors will appear.
For example, a metal halide lamp, which casts a whitish
light, can have a CRI as high as 90. A high pressure sodium
lamp, which imparts a yellowish color, has a CRI as low as
20. Therefore a metal halide source will be more appropriate
for color sensitive areas even though a high pressure sodium
lamp may be more efficient by providing greater lumens
per watt.
Glare
There are two types of glare, direct glare and reflected glare. Direct glare
occurs when light travels directly from the lamp source to the eye. Reflected
glare, also known as veiling reflections, results when light reflects from a shiny
surface, such as from a luminaire’s reflector, or other glossy surfaces within
the field of view. Glare can cause fatigue, headaches, annoyance, discomfort
and productivity loss due to reduced visual performance and visibility.
Direct glare can be reduced using the following techniques or combinations
of techniques: 1) paint the ceilings white and choose luminaires with high
(15-25%) uplight component to reduce the harsh contrast of the high
luminance source and the dark background 2) choose luminaires with deep
reflectors that block the lamp from the field of view 3) choose fixtures with
louvers or lenses to conceal the lamp 4) decrease the luminance of the source
by using lower wattage lamps and spacing fixtures closer together.
Reflected glare can be reduced using the following techniques or
combination of techniques: 1) position the lighting fixture or the task so that
the reflected image is directed away from the observer 2) select fixtures with
adequate shielding or diffusing media 3) use lower luminance lamps and
space fixtures closer together.

Lighting Economics
First cost or unit costs should not be the only consideration when
examining the economics of a lighting system. A better gauge is
how efficiently the entire lighting system will operate over time.
RELIGHT
Reduction in System Wattage
over existing system
Innovation that Makes a Difference
Replacing an existing 400W Metal Halide System with
Holophane’s premier luminaires featuring ISD
SuperGlass with 250W pulse start provides more light
while significantly reducing energy consumption.
It is hard to place a dollar value on lighting deficiencies such as
direct and reflected glare, shadows or uneven light distribution.
However, experience shows that as the purchasing price for
a lighting system decreases within limits, operating costs go
up. This is reasonable since a commodity grade luminaire
often is not as robustly designed and constructed as a more
highly engineered system. In addition, commodity grade
luminaires are usually made of inferior quality materials.
A lighting system’s design, materials, and construction will
dictate its usefulness, efficiency and durability over time.
The final price however, will be determined by the lighting
solution’s performance and its short-term and long-term
operating costs.
Holophane lighting solutions provide the best combination of
lighting performance with low owning and operating costs.
State-of-the-art optical systems promote energy efficiency
and wider spacing between luminaires. Quality materials and
a highly engineered design assure the luminaires provide
reliable performance with minimal maintenance for many
years.
Holophane’s software, ‘SALE’, is a financial lighting program that
compares the total costs of ownership for two or more different lighting
systems. The program evaluates the systems in terms of initial costs,
maintenance costs and annual operating costs. The installed cost is
only the first part of the equation. Higher initial costs may be quickly
offset by greater energy efficiency and lower maintenance costs over
the life of the luminaires, thereby yielding an overall lower total cost of
ownership.
‘SALE’ compares systems in terms of payback time and net present
value. The user may make comparisons based on any combination of
installation, energy, and maintenance costs. Under installation costs,
the user has the option to include or not include variables associated
with conduit, wiring, outlet boxes and fixture installation. This means
the user can compare systems based on energy and maintenance costs
versus initial fixture costs alone providing a clearer picture of the total
cost of ownership.

Lighting system slashes energy consumption, boosts illumination for Bearing Manufacturer
Rising energy costs have incited many companies to take a second look at their electrical systems. When
the management at FAG Bearings Corporation decided to retrofit the aged lighting system at its Joplin,
Missouri plant, the main objective was to reduce energy consumption.
FAG Bearings is a German-owned manufacturer providing ball and roller bearings of all sizes and types.
Customers include many renowned machine, vehicle and device manufacturers all over the world. The
facility is comprised of four buildings totaling 250,000 square feet.
During the early stages of the project, an energy retrofit company was consulted about replacing just the
ballasts in the facility’s existing low bay lighting system. The system used 400-watt high-pressure sodium
(HPS) lamps.
“
We have received many positive
comments from employees who feel the
new lighting system helps them see
better. A number have indicated that
the lighting helps them produce a
higher quality product
”
— Charlie Kissell, electronic technician
for FAG Bearings Corporation
However, because of the fixtures’ poor physical condition, the decision was made to retrofit the entire
lighting system. Over the years, the plastic lenses on the luminaires had yellowed to the point that the
light output was substantially decreased and many of the relamp doors were broken or missing.
Holophane Enduralume® fixtures with enclosed optics were selected for the retrofit. The fixtures, which
use 400-watt pulse start metal halide lamps, include a non-yellowing borosilicate glass refractor for low
brightness and end of life lamp containment.
According to Charlie Kissell, electronic technician for FAG Bearings Corporation, the pulse start lamps
were selected because of their longer life and higher initial and maintained light levels. The metal halide
lamps also have excellent color rendering capabilities.
“Although energy reduction was our primary objective, we also constantly strive for methods to improve
the quality of our products,” said Kissell. “Because bearings are manufactured to very exact tolerances,
the lighting is critical to producing an in spec product.”
A total of 180 Enduralume fixtures are installed in Building A, replacing 225 low bay fixtures. The
Enduralume luminaires were mounted at 22 feet on the open pan metal deck ceiling, and spaced
20’ x 20’ on center.
Based on FAG Bearing’s production schedule, the Enduralume units were installed above existing
equipment during the off-shift hours. New mounting points were required since fewer luminaires were
used with greater spacing between the units. Illumination levels are 55 footcandles maintained.
The Enduralume fixtures are manually controlled and continuously illuminated. FAG Bearings installed
Enduralume fixtures in the other three buildings.

Lack of proper lighting can cause increased returns of goods, less productivity
and lower corporate profit. In some cases improper lighting can invite the
threat of possible operation shutdown or diminished brand image. Holophane
luminaires are optically engineered to provide enhanced visibility through high
vertical surface illumination required on processing equipment, displays,
signage, racks, finished goods, machinery, distribution areas, railroad cars,
trucks and containers to speed product identification, minimize fatigue, reduce
the possibility of pilferage and increase employee morale and productivity.
