Does Dimming Lights Save Energy?

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.

Does dimming LED lights save energy?

1 Answer. Yes, dimmers reduce energy consumption of dimmable LEDs. Unlike incandescent bulbs, the electricity used is fairly linear with the light output; at 50% brightness it should use roughly 50% of the power. Generally speaking, dimming will allow the bulbs to run cooler and extend their life spans.

Do dimmers waste electricity?

Does dimming the lights save energy? Light dimmers save energy by reducing the flow of electricity to the bulb and allowing lights to operate with lower power outputs. Since lights under less stress shine longer, dimmers are known to extend the life span of your bulbs, too.
