Eric Liu says that orders for the company¡¯s cob mcob tcob led tube lighting emitters are growing, helped by competitive pricing. He concedes that the lights using the company¡¯s emitters are still pricier than traditional fluroescent tubes lamps, but notes that LED tube lights are more durable. If more people buy LED tube lights lamps, prices will fall more quickly, he says.

Requirements for ignition resistance, or flame retardancy, depend on the UL codes governing the specific application and the materials used. High-powered LED tube light sources operate at temperatures as high as 80-110¡ãC. Polycarbonate resins offer superior ignition resistance for these types of operating conditions. For lower-voltage applications using Class 2 power sources requiring UL 94 HB and V-2 flammability requirements, polycarbonate, acrylics, and styrenic-based resins such as styrene acrylonitrile (SAN) can be considered as materials for lenses, covers, and optics. For more demanding LED tube lighting applications t5 ot t8 where Class 1 power sources are used, the materials requirement for optics and lenses is UL V-0 and, in some cases, UL 5VA. To ensure the required flame retardancy and compliance with their associated UL 94 restrictions, components must be rigorously tested.
