The U.S. market has taken the lead in the replacement of T8 LED tube lights with T5 LED tube lights, which Lee noted had little to do with the lights size. “T8 LED tube lights are being replaced with T5 LED tube lights because it is less efficient,” explained the chairman.
Both T8 and T5 LED tube lights have omnidirectional lighting properties, where the light beam angle reaches 360 degrees. However, the tube light casing and ballast design can obscure most of the tube light emissions, especially the larger T8 LED tube lights making it less efficient than the T5 LED tube lights.
