Application Reference

Installation

• Designed to easily install in standard 4” (102mm)

downlight housings*

• Quick install system utilizes a unique retention

feature. Simply attach socket to CR4. Move light to

ready position and slide into housing

CR4™ LED Downlight - 4"

Product Specifications

a patented approach that delivers an exclusive combination of 90+ CRI, beautiful light

characteristics, and lifelong color consistency, all while maintaining high luminous efficacy –

a true no compromise solution.

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 the 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 attic

insulation

• 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

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

ELECTRICAL SYSTEM

• Integral, high-efficiency driver and power supply

• Power Factor: > 0.9

• Total Harmonic Distortion: < 20%

• Input Voltage: 120V, 60Hz

• Dimming: Dimmable to 5% with most incandescent dimmers*

• Operating Temperature Range: 0-35˚C (32-95˚F)

Photometry

CR4-575L-27K-12-E26 BASED ON ONSPEX REPORT #: 2539163

Luminaire 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 luminaire efficiency of 100%.
