Metalux GPT High Output integrated LED Prismatic Panel uses back-lit LED technology in applications where a brighter, high quality, long-lasting light is needed. The GPT High Output Prismatic comes pre-installed with a 6 ft. flexible conduit that is fully wired for faster on-site installation. The LED panel light delivers over 7700 lumens at 54W and can replace traditional 4-lamp 128W fluorescent fixtures. The GPT HO has an acrylic prismatic lens that mimics the look and appearance of a fluorescent troffer. This flat panel light uses a 120-277V, FCC rated Class B, 0-10V dimming driver. Equipped with thoughtful features, like a flexible conduit, supply and dimming wire, and integrated grid retention clips, this LED light is the right choice for any lighting upgrade. The GPT flat panel can be used as a fluorescent troffer replacement or the primary retrofit luminaire found in retrofit projects for office, residential, retail, and healthcare applications.
