4" Architectural LED Downlight
LR4
Product Description
The LR4™ architectural LED downlight delivers up to 540 lumens of exceptional 90+
CRI light while achieving over 51 lumens per watt. This breakthrough performance is
achieved by combining the high efficacy and high-quality light of Cree TrueWhite®
Technology. The LR4 is available in moderate or deep recess, warm or neutral color
temperatures, and has a variety of trim options. It must be used with the Cree H4
housing, making the LR4 perfect for use in commercial new construction applications.

Durable cold-rolled steel housing protects LEDs, driver and power supply. Adjustable flip clips
resist heat while providing retention for flush ceiling fit

Thermal management system uses extruded aluminum heat sink 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 attic insulation with ambient
temperatures exceeding 60˚C

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

Zonal Lumen Summary
Diffusing lens shields direct view of LEDs while lower reflector balances brightness of lens with
the ceiling to create a low-glare high angle appearance. When installed with 30˚ trim, deep set
diffusing lens provides more precise optical control with greater visual cut-off
