A revolutionary way to generate high-quality white light, Cree TrueWhite® Technology mixes the light from the highest performing red and unsaturated yellow LEDs. This patented approach 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.

An innovative thermal management system designed to maximize cooling effectiveness by allowing free air movement around the heatsink and through the fixture. This breakthrough design and operating drive current of less than 350mA enables the LEDs to consistently run cooler, providing significant boosts to lifetime, efficacy, and color consistency.

High strength, lightweight polymer forms the reflector and driver housing.
Multi-functional heat sink and light bar doubles as the wireway for through wiring harness.
Two plastic tong hangers provided for surface or suspended installations. One tong hanger per unit plus one per row is required.
Hangers are adjustable along fixture to accommodate existing mounting points for upgrade projects. Hanger support required within 18 inches of end of fixture.
Individual fixtures may be connected end to end for continuous row mounting. Easy removal of individual fixtures mounted in continuous row.
Not intended for use in environments containing airborne corrosive agents such as chemical solvents, cleaners, or cutting fluids.

High-efficiency reflector with MicroMixing Optics which integrates the intense direct LED light and distributes optimally mixed indirect white light resulting in a comfortable appearance while maintaining high- efficiency optics.
Indirect LED strip eliminates direct view of highly efficient, lighting quality LEDs.

Integral through wiring harness (3#12 AWG power and 2#18 0-10V) with quick-connect plug connectors for easy and efficient continuous row installations while minimizing branch circuit wiring.
Room-side wiring access chamber with hinged door for easy electrical access.
Integral, high-efficiency driver and power supply.
