Product Specifications
CREE TRUEWHITE
®
TECHNOLOGY
A revolutionary way to generate high-quality white light, Cree TrueWhite
®
Technology is a patented
approach that delivers an exclusive combination of 90+ CRI, beautiful light characteristics, and
lifelong color consistency, all while maintaining high luminous efficacy – a true no compromise
solution.
CREE LED TECHNOLOGY
Cree’s total systems approach to product development is a comprehensive engineering philosophy
that combines the most advanced LED sources, driver technologies, optics and forms. The result
is highly-reliable luminaire solutions for both indoor and outdoor applications that reduce energy
use, extend lifetimes, and maximize illumination performance and quality.
ROOM-SIDE HEAT SINK
An innovative thermal management system designed to maximize cooling effectiveness
by integrating a unique room-side heat sink into the diffusing lens. This breakthrough
design creates a pleasing architectural aesthetic while conducting heat away from LEDs in
a temperature-controlled environment. This enables the LEDs to consistently run cooler,
providing significant boosts to lifetime, efficacy, and color consistency.
CONSTRUCTION & MATERIALS
• Durable 22-gauge steel housing with standard troffer access plate for electrical
installation
• One-piece lower reflector finished with a textured high reflectance white polyester
powder coating creates a comfortable visual transition from the lens to the ceiling
plane
• Includes t-bar clips and holes for mounting support wires enable recessed or
suspended installation
• Individual luminaires may be mounted end to end for a continuous row of illumination
OPTICAL SYSTEM
• Unique combination of reflective and refractive optical components achieves a
uniform, comfortable appearance while eliminating pixelation and color fringing
• Components work together to optimize distribution, balancing the delivery of high
illuminance levels on horizontal surfaces with an ideal amount of light on walls and
vertical surfaces. This increases the perception of spaciousness
• Diffusing lens integrated with upward-facing LED strip eliminates direct view of LEDs
while lower reflector balances brightness of lens with the ceiling to create a low-glare
high angle appearance
ELECTRICAL SYSTEM
• Integral, high-efficiency driver
• Power Factor:
= 0.9 nominal
• Input Power:
Stays constant over life.
• Input Voltage:
120-277V or 347V, 50/60Hz
• Operating Temperature Range:

Lumen maintenance values at 25˚C (77˚F) are calculated per TM-21 based on LM-80 data and in-situ luminaire testing
In accordance with IESNA TM-21-11, Projected Values represent interpolated value based on time durations that are within six times
(6X) the IESNA LM-80-08 total test duration (in hours) for the device under testing ((DUT) i.e. the packaged LED chip)
