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.

CONSTRUCTION & MATERIALS

• Durable cold-rolled steel housing protects LEDs, driver and power supply. Adjustable flip clips

resist heat while providing retention for flush ceiling fit

• Thermal management system uses extruded aluminum heat sink to conduct heat away from

LEDs and transfer it to the plenum space for optimal performance. LED junction temperatures

stay below specified maximum even when installed in attic insulation with ambient

temperatures exceeding 60˚C

• Suitable for insulated and non-insulated ceilings

• Snap-in trim (sold separately) integrates reflector and flange to redirect light while creating a

comfortable visual transition from the lens to the ceiling plane

OPTICAL SYSTEM

• Unique combination of reflective and refractive optical components achieves a uniform,

comfortable appearance while eliminating pixelation and color fringing. This ensures smooth

light patterns are projected with no hot spots and minimal striations

• 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 shields direct view of LEDs while lower reflector balances brightness of lens with

the ceiling to create a low-glare high angle appearance. When installed with 30˚ trim, deep set

diffusing lens provides more precise optical control with greater visual cut-off

ELECTRICAL SYSTEM

• Integral, high-efficiency driver and power supply

• Power Factor:

> 0.9

• Input Voltage:

120V, 60Hz

• Dimming

: Dimmable to 20% with most incandescent dimmers*

REGULATORY & VOLUNTARY QUALIFICATIONS

• ENERGY STAR® qualified

• cULus Listed

• Exceeds California Title-24 high efficacy luminaire requirements

• IC air-tight rated, tested in accordance with ASTM E283

• Suitable for wet locations
