LR6-10L-35K-GU24 BASED ON CESTL REPORT TEST #: PL06010-001 Fixture photometry has been conducted by a NVLAP accredited testing laboratory in accordance with IESNA LM-79-08. IESNA LM-79-08 specifies the entire luminaire as the source resulting in a fixture efficiency of 100%. ® 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 137 • Suitable for insulated and non-insulated ceilings 274 • 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 412 • 5.5" (140mm) pigtail OPTICAL SYSTEM • Unique combination of reflective and refractive optical components achieves a uniform, comfortable appearance while eliminating pixelation, hot spots and minimizing glare 90˚ 0 70˚ 50˚ 549 0˚ 20˚ 0˚ • 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 • Deep set polycarbonate diffusing lens shields direct view of LEDs and provides greater visual cut-off 90˚ Average Luminance Table (cd/m2) Horizontal Angle ELECTRICAL SYSTEM • Integral, high-efficiency power supply • Power Factor: minimum 0.9 • Total Harmonic Distortion: < 20% Vertical Angle • Input Voltage: 120V, 50/60Hz or 277V, 50/60Hz • Dimming: 120V dimmable to 5% with most incandescent dimmer. 277V dimmable to 5% with trailing edge dimmers.
