Does dimming lights save energy?

Dimming lights can help save energy because it reduces the amount of power used by the light. As the light intensity is decreased, less energy is required to produce the same level of illumination. This can lead to a reduction in energy consumption and can help to lower electricity bills.

However, it's important to note that not all types of lights are dimmable. Incandescent and halogen bulbs can be dimmed using traditional dimmer switches, but compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs) may not be compatible with traditional dimmer switches. So, it is important to use dimmer switches that are specifically designed to work with CFLs or LEDs.

In addition, dimming lights can also extend the lifespan of the light bulb, because dimming the lights reduces the amount of stress on the bulb, which can cause it to burn out more quickly.

Overall, dimming lights can be an effective way to save energy and extend the lifespan of light bulbs, but it's important to use dimmer switches that are compatible with the type of light being used.
