The PowerGrid from GE Lighting, part of the Tetra Architectural Series, is a modular LED system that replaces fluorescent lights in applications that require broad, uniform lighting, such as backlighting walls, illuminating ceilings, and undercabinet task lighting. According to GE, PowerGrid is up to 64% more energy efficient than fluorescent light sources and offers up to 50,000 hours of life. The PowerGrid comes in packages of 14'-long grids with 21 modules and six LEDs per module. Six PowerGrid options are available with white or warm-white color temperatures, ranging from 94 to 136 emitted lumens.
