Lamp dimmers and their circuits must be compact, energy efficient and able to operate reliably in confined spaces. Lamp brightness is varied by controlling the conduction time of each half-cycle of ...

One of the biggest challenges for new, energy-efficient CFL and LED-based lights that will replace incandescents is working with existing triac-based dimmer switches. Triac dimmers vary widely in both ...

My new house is a fixer-upper, and on the to-do list were two dimmer switches that did not work. One fed overhead lights; the other fed the lamp in a ceiling fan. Once I pulled the ceiling fan dimmer, ...
