LED junction temperatures stay below <br />specified maximum even when installed in insulated ceilings <br />• Suitable for insulated and non-insulated ceilings <br />• One-piece aluminum lower reflector redirects light while also <br />conducting heat away from LEDs. It creates a comfortable visual <br />transition from the lens to the ceiling plane and easily accommodates <br />CRT6 snap-in trims <br />OPTICAL SYSTEM <br />• Unique combination of reflective and refractive optical components <br />achieves a uniform, comfortable appearance while eliminating pixelation <br />and color fringing. This ensures smooth light patterns are projected with <br />no hot spots and minimal striations <br />• Components work together to optimize distribution, balancing the <br />delivery of high illuminance levels on horizontal surfaces with an ideal <br />amount of light on walls and vertical surfaces. This increases the <br />perception of spaciousness <br />• Diffusing polycarbonate lens shields direct view of LEDs while lower <br />reflector balances brightness of lens with the ceiling to create a <br />low-glare high angle appearance <br />ELECTRICAL SYSTEM <br />• Integral, high-efficiency power supply <br />• Power Factor: > 0.9 <br />• Total Harmonic Distortion: < 20% <br />• Input Voltage: 120V, 50/60Hz <br />• Dimming: Dimmable to 5% with select incandescent dimmers. Forward <br />phase (triac) and reverse phase dimming only. <br />• Reference <br />http://lighting.cree.com/products/indoor/retrofit-downlights/crt-series <br />for recommended dimmers <br />• Use only lighting controls with neutral connection or controls intended <br />for use with LED fixtures <br />• Operating Temperature Range: -25˚C to +35˚C (-13˚F - +95˚F) <br />REGULATORY & VOLUNTARY QUALIFICATIONS <br />• cULus Classified <br />• Suitable for wet locations for covered ceilings only <br />• Meets FCC Part 15, Subpart B, Class B standards for conducted and <br />radiated emissions <br />• ENERGY STAR ® certified.
