Fluorescent light facts
WebHeat: LEDs emit very little heat. In comparison, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat. Lifetime: LED … WebDec 8, 2024 · In a CFL, an electric current is driven through a tube containing argon gas and a small amount of mercury vapor. This makes invisible ultraviolet (UV) light. The UV light hits a coating on the inside of the tube, which then gives off visible light. CFLs use about 75 percent less energy than incandescent bulbs. Saving energy helps the environment.
