CONSTRUCTION & MATERIALS • Durable aluminum housing protects the light source. Adjustable flip clips provide robust retention for flush ceiling fit • Thermal management system uses integral heat sink to conduct heat away from LEDs for optimal performance. LED junction temperatures stay below specified maximum even when installed in with worst case installations LR6-18L 0 90 Intensity (Candlepower) Summary 80 183 70 367 60 550 • Suitable for non-insulated ceilings only • One-piece aluminum lower reflector redirects light while also conducting heat away from LEDs. It creates a comfortable visual transition from the lens to the ceiling plane and easily accommodates LT6 snap-in trims OPTICAL SYSTEM • Unique combination of reflective and refractive optical components achieves a uniform, comfortable appearance while eliminating pixelation, hot spots and minimizing glare • 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 50 733 40 917 1,100 0 10 20 • Deep set diffusing lens shields direct view of LEDs and provides greater visual cut-off 30 Zonal Lumen Summary • Power Factor: > 0.9 Zone Lumens % Lamp % Fix • Input Voltage: 120V, 60Hz 0-30 424 42.42% 42.42% 0-40 629 62.89% 62.89% 0-60 897 89.71% 89.71% 0-90 1000 100% 100% REGULATORY & VOLUNTARY QUALIFICATIONS • ENERGY STAR® qualified • cULus Listed Mean CP 0° 1059 5° 1056 15° 1007 25° 846 35° 602 45° 369 55° 212 65° 106 75° 55 85° 10 90° 0 0° ELECTRICAL SYSTEM • Integral, high-efficiency driver and power supply • Dimming: Dimmable to 5% with certain incandescent dimmers* Angle Reference www.cree.com/lighting for detailed photometric data • Exceeds California Title-24 high efficacy luminaire requirements • Suitable for damp locations Installation * Reference www.cree.com/lighting for recommended dimmers • Designed to easily install in standard 6" housings from Cree and other manufacturers* • Quick install system utilizes a unique retention feature.
