Some things just seem to be a natural fit for productive office environments.
Heating is one of them. Cooling is another. Fail to adjust either one to a comfortable
level and employee productivity begins to suffer.
Similarly, a modern lighting system needs to be flexible enough to reduce glare, provide just
the right level of illumination necessary for different tasks and reduce eye fatigue to support
optimum employee comfort and productivity. Leviton’s Centura Lighting System lets you
realize this new formula for greater worker productivity. And, it comes just in time.
Today’s workplace has become more dynamic then ever before with employees moving
between multiple tasks during the course of a single workday. From the high levels of
illumination needed to read documents with small text, or engineering drawings, to computer
tasks requiring a significantly lower light level, each task requires an appropriate level of light.
What’s more, that level differs for each employee, depending on both the immediate task
at hand and personal factors. For example, the ability to focus and the acuity of the eye
deteriorate with age. A sixty-year old employee’s eyes receive only about forty percent as
much light as someone in their late twenties or early thirties, requiring significantly more
light to perform similar tasks.
For both reasons, the one-size-fits-all approach of defined light levels falls far short of the
needs of a majority of office employees. In one study of workers in a "one-light-fits-all"
environment, fully 57% of them complained about stress due to poor lighting conditions*.
The message is clear. Provide workers with the ability to adjust light to keep pace with these
changing needs and the health, comfort and productivity of your work force will improve.
With the costs of people far outweighing all other costs combined in a company, even
a modest improvement in worker productivity and staff retention will easily offset the costs
of an advanced lighting control management system. Use of modern lighting controls as
a tool to improve the wellbeing of employees clearly makes a concrete difference in
today’s competitive environment.

CENTURA™
Raising The Bar For High Quality
Lighting Control Management
The innovative new Centura modular lighting control
system for dimming fluorescent ballasts** makes
a decisive new contribution to corporate cost reductions
by both raising worker productivity through greater
individual control over lighting and by lowering the
energy cost of energy-saving fluorescent lighting
even further with innovative lighting technologies.
CENTURA™
Responding To Changing Lighting Requirements
Through User-Friendly Manual Controls
The Centura lighting control system recognizes the
motivating force of visual comfort in greater worker
productivity by providing convenient manual override of
automated settings to permit precise lighting for individual
needs. Convenient access is realized via wall-mounted
and infrared remote controls or directly through individual
PC workstations. Employees get the right light for every
situation and, in the process, provide productivity gains
to the corporate bottom line.
CENTURA™
Increasing Energy Conservation Through
Innovative Lighting Control Technology
Modern office buildings are becoming more intelligent by
necessity. The apparent developing shortage of generating
capacity and the rapid rise in energy costs demand that
lighting, the number one source of energy consumption in
commercial office spaces, be handled in new ways that
optimize energy efficiency.
Overall Energy Cosumption
In the past, the benefits of energy-efficient lighting on
the corporate bottom line came, for the most part, from
investments in hardware, such as energy-efficient lamps
Energy Cosumption
and ballasts. The Centura Lighting System’s enhanced
Energy Savings
energy conservation capabilities start by picking up where
these hardware-based technologies leave off.

"daylight harvesting," – with the precise

control of fluorescent lighting levels to
Daylight
maintain a pre-selected level of
Artificial light
illumination, delivering greater energy
cost reductions than "dimming only"
systems.
Centura Hybrid Lighting Control - A Modular Energy-Efficient System
Built To Meet Ever Changing Needs
Centura uses strategically located
photocells to measure the changing
75%
contribution of free natural daylight to
a desired user-programmed level of light
in a room. Centura then automatically
dims or brightens the fluorescent
lighting it controls, adding only as
much artificial light as needed to
precisely maintain that programmed
level. The results are a seamless
blending of light sources that goes
virtually unnoticed by the room’s
occupants as well as a significant
reduction in overall energy consumption
by as much as 60%.
"Daylight Harvesting" technology maintains
a programmed level of light by precisely
adjusting the output of a room’s fluorescent
lighting to compensate for changing levels of
available free natural daylight

A Modular

System
Built To Meet
Ever Changing
Needs
Centura combines the technology of "daylight harvesting " with a host of innovative
energy-efficient modular lighting controls, including dimmers, timers, occupancy
sensors and photo-sensors that dim or turn off fluorescent lighting when a space
is not being used. Centura incorporates the ability to interface with any Leviton
occupancy sensor to provide even greater energy savings. When single or multiple
occupancy sensors are installed, programmed interior lighting is automatically turned
OFF when the room is vacant and back ON to the programmed level when
occupancy is detected. The use of movement sensors means energy savings
up to a proven 50%.
An exclusive Centura convenience feature permits easy programming of the
in-ceiling Centura Dimming Power Pack through Centura companion Wall
Controllers or from a PC, using Administrator software. This eliminates
the need to program a hard-to-reach in-ceiling unit directly.
In general, the Centura Dimming Power Pack has been programmed to follow a
series of energy efficient protocols based on a least light law. By following the least
light law, the Power Pack will adjust the light level to the least light called for by
all of the inputs.
For example, if the Power Pack is turned on (either manually or by an occupancy
sensor) and the Light Maintain Level calls for a lower output level than the last
manual level, the lights will adjust to the lower Light Maintain Level. On the other
hand, if the manual preset level is lower than the Light Maintain Level when the
Power Pack is turned on, the lights will adjust to the manual preset level – because
it’s the lowest level in this case. (Note: You CAN manually override this level.) The
least light law is applied at all times, except when overriding Emergency, Service
Switch or Time Clock inputs are activated.
Centura can be effectively tied into building emergency, load shedding and time
clock systems. In the emergency mode, it switches lights to full brightness when
the emergency system is activated. In load-shed mode, it reduces light levels to
25% of the current level selected to save energy during peak usage periods.
The time clock function shuts lights OFF after the building is no longer occupied,

offering up to 30% in energy savings.

To The Task At Hand
Optimum Lighting
For Computer Workstation
A worker sets a low light “maintain level” around her
workstation for greater visual comfort via Leviton Personal
Dimmer software on her computer. Subsequently, the blinds
are shut to reduce monitor glare from outside light. Centura
responds automatically to the drop in natural daylight by
compensating with an increase in the fluorescent lighting’s
contribution to the previously selected level of overall
illumination or “maintain level.”
Increased Lighting
For General Office Tasks
Increased Lighting For General Office Tasks
Turning from the workstation’s monitor to more general
office tasks, Centura is set to a full bright “maintain level”
via Leviton Personal Dimmer software on her computer.
The blinds are also opened again to let in more natural
daylight. Centura automatically sets the fluorescent lighting’s
contribution to 65% of the programmed overall illumination
or “maintain level,” making use of free natural daylight to
supply the remaining 35%.
Full Illumination
Aids Night Crew Clean-up
Centura is set to turn lights ON after normal working hours
when occupancy sensors detect motion. Night crew can
then easily locate and tap Centura Dimming Controller for
full brightness while cleaning. Lights shut off automatically
when they leave. Lights then follow the “least light law”
and turn on at the previously programmed lower maintain
level when daytime employees return.
