Cree TrueWhite Technology Option:
A revolutionary way to generate high-quality white light, Cree TrueWhite® Technology is 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.
Cree LED Technology:
Cree's total systems approach to product development is a comprehensive engineering philosophy that combines the most advanced LED sources, driver technologies, optics and forms. The result is highly reliable luminaire solutions for both indoor and outdoor applications that reduce energy use, extend lifetimes, and maximize illumination performance and quality.
Room-Side Heat Sink:
An innovative thermal management system designed to maximize cooling effectiveness by integrating a unique room-side heat sink into the diffusing lens. This breakthrough design creates a pleasing architectural aesthetic while conducting heat away from LEDs in a temperature-controlled environment. This enables the LEDs to consistently run cooler, providing significant boosts to lifetime, efficacy, and color consistency.
Lumen Maintenance Factors:
• Reference www.cree.com/lighting for detailed lumen maintenance factors.
Construction & Materials:
• Durable 20-gauge steel housing with standard troffer access plate for electrical installation.
• Field replaceable light engine integrates LEDs, driver, power supply, thermal management, andoptical mixing components.
• One-piece lower reflector finished with a textured high reflectance white polyester powder coating creates a comfortable visual transition from the lens to the ceiling plane.
• Provided t-bar clips and holes for mounting support wires enable recessed or suspended installation.
• Individual fixtures may be mounted end to end for a continuous row of illumination.
NOTE: Reference www.cree.com/lighting for detailed instructions on field replacement of the light engine.
• Unique combination of reflective and refractive optical components achieves a uniform, comfortable appearance while eliminating pixelation and color fringing.
• 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 lens integrated with upward-facing LED strip eliminates direct view of LEDs while lower balances brightness of lens with the ceiling to create a low-glare high angle appearance.
