The popularity of halogen light is still increasing, and rightly so because of some distinct advantages: the colour temperature is agreeable and excellent to work by, the efficiency is relatively high, and the lamps are powered by a low voltage. One disadvantage of halogen lights is rarely mentioned, however, although it is pretty obvious: conventional light dimmers can not be used. In this article an ingenious circuit is described to overcome that disadvantage.
