Dimmable lights are lighting fixtures that allow users to adjust the brightness of the light according to their needs or preferences. This feature is commonly found in various types of bulbs, including LED, incandescent, and halogen lights. Dimming can create a cozy atmosphere, enhance mood, or save energy by using less light when full brightness is not necessary. To use dimmable lights, a compatible dimmer switch is required, which controls the amount of electricity flowing to the light source. Dimmable lights are popular in homes, restaurants, and theaters, as they provide flexibility in lighting design and can improve the overall ambiance of a space.
