Dimmers are electronic devices that allow users to control the brightness of light fixtures. They work by varying the amount of electricity flowing to the light bulb. They can make the atmosphere more comfortable whether reading a book or watching a movie. Dimmers are versatile in terms of light source (R, L, C, ESL, LED) and other technical refinements such as "minimal brightness control for automatic blinking" or wireless control. The maximum load ends at 10,000 VA.
