1.3 Nomenclature 1.4 Environmental aspects The name of the lamp family is: Life Cycle Assessment (LCA) studies show that at least 99% of ‘TL’ fluorescent lamps light sources’ contribution to pollution is caused by their energy consumption.This means the higher the efficacy, the better from The technical name of the product is: the environmental (and economical) point of view. Less energy ‘TL’5 consumption means less energy generation, which will have a 5: tube diameter of 5/8 inch positive effe
