WebJun 5, 2024 · Not only do modern light dimmers save you energy, but they also extend the life of your light bulbs! Dimmers use a “Triac Switch” to rapidly turn a light circuit on and off to reduce the energy flowing to a light bulb. This switch will cut the energy running to the fixture up to 120 times in one second. WebOnly around 10% of the electric power used by an incandescent light bulb produces light. The other 90% is emitted as heat. Because of this high heat output you’ll see incandescent bulbs used as heating lamps, grow bulbs …
