Introduction to the Hi-Lite
Studio Quality Lighting Specifically Designed for the Videoconferenc-
ing Environment
“Lights, camera, action!” There’s a reason why lights
come first in this famous expression. Professional
photographers, television engineers and motion picture
studios will all agree that lighting is just as important
as the rest of the production considerations. In other
words, the quality of the image is directly proportional to
the quality of the lighting. This rule is consistent with all
optical applications and is especially true with images
transmitted by videoconferencing codec units.
Compared to the human eye, the video camera is less
tolerant of unfavorable lighting conditions. It detects
and processes unwanted information such as flicker and
glare caused by conventional light sources. Videocon-
ferencing further compounds this problem by compress-
ing and decompressing the video signal before transmit-
ting it over many miles of telephone lines. The best way
to compensate for these inherent problems is to feed the
camera the proper amount of high quality light.
Don’t worry, there’s no need to become a lighting expert.
We can supply you with the tools and suggestions to
master the videoconferencing challenges that arise due
to poor lighting conditions.

Features & Benefits
Features
Adjustable Light Intensity (dimmable Hi-Lite models
only)
The optional dimming feature on the Hi-Lite units allows
the light intensity to be adjusted to provide more key light
for people with darker skin tones and less for those with
lighter complexions. Adjustable lighting also provides
essential fill light, which fills in dark areas and dead
spots left by conventional lighting. The result is a sharp,
crisp picture with a remarkable improvement in contrast
and definition.
Proper Color Temperature and Rendering
Hi-Lites are engineered to provide the highest quality of
diffused light for videoconferencing. Video cameras at-
tain peak performance between 2800°K to 4100°K. With
a color temperature of 3200°K and a Color Rendering
Index (CRI) of 82, our lamps set the standard for high
quality videoconference lighting.
No Interference
Unlike conventional fluorescent or incandescent lighting,
the Hi-Lite uses a high frequency ballast which provides
an even, low flicker output, as well as virtually silent
operation.
Low Power Consumption Generates Very Little Heat
The Hi-Lite uses three compact, fluorescent twin-tube
lamps per fixture. It needs less than 110 watts to
produce the same quality light as Tungsten or Halogen
lamps, which require as much as 500-1500 watts!
Less energy for operation means less heat dissipated.
Even after long hours of operation, the fixture is still cool
to the touch. Participants remain cool and comfortable
for the duration of the videoconference.

• Dimmable (built-in infrared or external) or non-dim-
mable.
• Adjustable positioning allows lights to be rotated and
tilted up to 180º .
• Directional, diffused light source.
• Ceiling or tripod installation.
Recently redesigned to accommodate a wider variety of
ceiling grids, operating voltages and dimming options. The
Original Series includes three compact fluorescent T5 lamps,
an opal diffuser, and an electronic dimming ballast. The
XL model includes a built-in infrared dimmer, the EX is
wired for external three-wire dimming systems, and the
NX is our non-dimming model. Each light also includes
an installation kit complete with ceiling grid adapters and
safety cabling.

Features & Benefits
Recessed Hi-Lite Series (XLR, EXR & NXR)
The new Recessed Series offers a choice of dimming
preferences and multiple operating voltages in a flush-
mount 2’x2’ fixture that will either drop in to a ceiling grid
or can be installed into a drywall-based application.
Unique Features
• Recessed flush-mount enclosure.
• Available in 120, 220-240 or 277 volts.
• Dimmable (built-in infrared or external) or non-dim-
mable.
• Low-profile construction.
• Directional, diffused light source.
• Removable electronic chassis.
The Recessed Hi-Lite Series is the newest addition to
our lighting solutions for videoconferencing. The Re-
cessed Series effectively addresses the challenges
presented by the modern day boardroom. Ideal for high-
end boardrooms and conference rooms, the recessed
Hi-Lites provide the high-quality lighting required by the
videoconferencing camera without compromising the
aesthetics of the boardroom.
Recessed Series Hi-Lites feature multiple dimming op-
tions and operating voltages. The XLR model includes
a built-in infrared dimmer, the EXR is wired for external
three-wire dimming systems, and the NXR is our non-
dimming recessed model. All three recessed models
include two 50-watt, 3500ºK compact fluorescent lamps
in a flush-mount, recessed enclosure. Each light also
includes an installation kit complete with safety cabling
and electrical connectors.

Safety Precautions
Safety Precautions for All Hi-Lite Models
To prevent damage to the equipment and operating per-
sonnel, please observe the following precautions:
Use the correct voltage source as specified by the label
on the back of the unit.
Make sure that the voltage source contains a satisfac-
tory path to ground.
Do not operate the unit where fluids can come into con-
tact with the electrical components.
When changing the lamp:
1. Disconnect the electrical supply.
2. Allow the unit to cool.
3. Use only part # 8-13698 or 8-13699 replacement
lamps, which you can purchase from your authorized
Hi-Lite dealer.
Other than changing the lamp, there are no user service-
able components. Opening the unit will expose danger-
ous voltage levels and sensitive electronic components.
A qualified technician should perform all repairs.
To prevent the unit from damaging condensation and
thermal shock, certain procedures must be followed:
1. In cold weather, always put the unit in a moisture
proof container or enclosure before transporting.
2. Either keep the unit warm during transportation, or
allow sufficient time for it to warm up at the destina-
tion. Keep the unit in the original moisture proof
package while it warms up to room temperature.
(The goal is to prevent warm, moist air from striking
the cold electronic components, which will cause dam-
aging condensation).
