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: 0˚C - + 35˚C (32˚F - + 95˚F) • Total Harmonic Distortion: < 20% CONTROLS • Step dimming to 50%* • Optional continuous dimming to 5% with 0-10V DC control protocol* • Optional Lutron EcoSystem® Enabled option allows seamless integration with Lutron EcoSystem controls* REGULATORY & VOLUNTARY QUALIFICATIONS • cULus Listed • Suitable for damp locations • Designed for indoor use • UL924 (EB14 option) • DLC qualified.
