The move to LED – Why is it happening?
 LED is a much better source for task lighting
 Maintenance free operation reduces costs
 Much less heat than halogen/incandescent
 Low voltage operation is much safer
 Small, slim package fits in tight spaces
 Easily controllable through the use of optics
 Works best in directional light applications
 Variety of beam distributions
 Low impact/load on machine power supply
 Impervious to shock or vibration
3
What are the barriers to change?
 Currently, a very limited installed base
of products in the marketplace
 Still only a few products on the market,
able to withstand industrial use and
conditions on a daily basis
 Initial product costs are higher
compared to older technologies
 Costly to develop for Industrial
applications, must be = or > IP65
 Often MRO purchase is a product
identical to light needing replacement
 Not yet a viable replacement for very
high lumen output requirements
4
What is the time frame for change?
 Within 5-8 years, incandescent lamps
will be obsolete and halogen will be in
a very steep decline. Essentially all
incandescent extinct within 10 years
 Fluorescent and HID will continue to
be used but in lower quantities and
primarily for low-cost ambient
applications that are easy to re-lamp
 Within 5 years, all major machine
manufacturers will have switched over
to LED for lighting the interior of their
machines and equipment
 Within 5 years, generally all new task
lights will use LED, not fluorescent
5
Which customers are making the change now?
 Customers tend to be larger, Fortune 500
type companies looking to systematically
upgrade facilities and equipment
 These companies typically have “Green”
initiatives for removing inefficient light
sources with the goal of reducing energy
consumption and carbon emissions
 Sophisticated manufacturing such as
aircraft, automotive, electronics,
semiconductors, medical, defense
 OEM’s looking to reduce heat, size and
footprint of lighting equipment within their
machines
 Machine rebuilders looking to upgrade
6
Which customers will be more resistant to change?
 Mid-size and smaller operations who’s
primary concerns involve initial product
acquisition costs
 Customers whose applications require
less sophisticated lighting equipment
and do not require waterproof, vibration
or impact protection
 Customers choosing to replace lighting
equipment on an “as-needed” basis
with identical products to those being
replaced
 Customers burned by inferior quality
LED equipment which often burn out
faster than traditional products replaced

LED – Advantages and disadvantages
Cost advantages
 Low energy consumption
 Low heat emission
 Long lifetime of the light source
 No maintenance costs
 Low disposal costs
Cost disadvantages
 Efficiency still must be improved
(Price / Lumen)
 High development costs for the
LED PCBs
 Higher initial product cost
LED – Advantages and disadvantages
Technical design advantages
 Small in size (fit in conventional lights)
 Modern designs with slim housings
 Possibility of individual light shapes
thanks to different LED arrangements
 Vibrant color using different color LED’s,
i.e. red, blue, green
 Instant ON/OFF functionality
 Ability to develop precise optics
Technical design disadvantages
 Color differences are often visible,
in spite of identical binnings
LED – Advantages and disadvantages
Technical advantages

Shock and vibration resistant

Instant on/off operation, no warm up

Precise light orientation (beam angle)
without additional reflector thanks to the
integral LED optics

No UV / IR radiation

No bulb socket required

Safety through protective low voltage

Good color rendering properties (RGB)
Technical disadvantages

Poor color rendering properties (about
Ra 85) with white LEDs

Color temperature & color rendering
depend on the temperature and age of
the LED
LED vs. Fluorescent vs. Halogen



LED

Best suited for task lighting

Lower power consumption

Very little heat output

Extremely long life (50,000+ hours)
Fluorescent

Best suited for area (ambient) lighting

Low power consumption

Moderate heat output

Long life (up to 30,000 hours)
Halogen (Incandescent)

Can be task or ambient

High power consumption

High heat output

Moderate/Low life (<5,000 hours)

LED’s as a Task Light Source
 Sweet spot for LED Lighting
 Excellent at penetrating through
liquids and coolants
 Low heat in the direction of beam
minimizes baking on of coolants
 Power supply can be integrated
into machine switch
 Instant on/off with no impact on
lamp life
 Multiple beam angles available
for precise focus and positioning
 Operates at a very high frequency
12
Why Waldmann??
 Products are “Professional Grade”
and designed specifically for heavy
daily use in harsh, demanding
Industrial applications
 Lower cost alternatives tend to
have poor quality components and
limited performance and control
 Lower quality products fail in these
environments for two primary
reasons:

Excessive heat build-up

Liquid intrusion
 Similar grade differences as in tools
13
Why Waldmann??
 Our products are much safer to
use than lower quality products

Elimination of pinch points

Concealed springs that will not
corrode and break

Mounting and adjustment
hardware is much more robust
and much less prone to failure

Hardware or adjustment failure
can compromise employee safety

Lower quality components add to
worker fatigue and eye strain
 Our warranty and service is
superior to our competitors
14
Summary…Why LED??
 LED is taking over the Industrial Task
Lighting space, the benefits
overwhelming, incandescent sources
will soon be obsolete
 New product development will almost
exclusively focus on LED or a
combination of LED and fluorescent
 Large, environmentally concerned
organizations are the early adopters of
LED technology
 OEM’s are moving to LED in new
machines and away from fluorescent
 Green solutions are becoming
essential in new construction
