Troffer Kits are a collection of LED and T8 lay-in troffer retrofit kits for commercial applications with grid ceilings. Also known as reflector kits or light conversion kits, troffer Kits are used to upgrade your existing light fixture to a newer technology. Labor cost may be cut significantly by retrofitting when comparing to a new fixture. Products include 1x4, 2x2 and 2x4 troffer. These products are chosen because of their energy savings.
