Product Specifications
CONSTRUCTION & MATERIALS
• Durable upper housing protects LEDs, driver and power supply.
Adjustable flip clips resist heat while providing retention for flush
ceiling fit
• Thermal management system uses both upper housing and lower
reflector 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 insulated ceilings
• Suitable for insulated and non-insulated ceilings
• 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
CRT6 snap-in trims
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 polycarbonate lens shields 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 power supply
• Power Factor: > 0.9
• Total Harmonic Distortion: < 20%
• Input Voltage: 120V, 50/60Hz; 120-277V, 50/60 hZ
• Dimming: Dimmable to 5% with select incandescent dimmers at 120V
only. Forward phase (triac) and reverse phase dimming only.
