Product Specifications

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

Lumen maintenance values at 25˚C (77˚F) are calculated per TM-21 based on LM-80 data and in-situ luminaire testing

2

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)

3

In accordance with IESNA TM-21-11, Calculated Values represent time durations that exceed 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)
