Ever wondered if dimmers have an effect on energy use? Take a close look at light dimmers! read more
Leds work using dc voltage. The higher the voltage, the more light the give out. The higher the voltage, the more current they use, which relates to energy. Manufactures use various ways of changing the dc voltage to change the brightness. Some just change the voltage using a transister but this is the most expensive and least efficent way. read more
