Light output efficiency
WebLED is a highly energy-efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs -- especially ENERGY STAR rated products -- use at least 75% less energy, and last up to 25 times longer, than incandescent lighting. Webdisplaced by slimmer T8 lamps with higher-efficiency electronic ballasts. Lamp and ballast manufacturers continue to improve linear fluorescent light output, efficacy, operating life, and color quality. Similarly, luminaire manufacturers have made significant advances in efficiency and optical control of linear fluorescent fixtures.
