Q: My home is about 20 years old. My problem is with the lights in the kitchen. Sometimes they work and sometimes they don’t. When I turn on the switch, the light flickers or just partially lights. I ...

Dimming fluorescent lamps is an attractive feature that provides mood and brightness effects as well as having tremendous energy savings potential. Designing a dimmable electronic ballast, however, is ...

Electronic ballasts used in fluorescent lighting systems can experience high failure rates, due to the fact that the ballast manufacturer may not have considered all failure mechanisms or provided ...

If you want to improve lighting system efficiency, ballast selection is critical. Today's most popular energy-efficient lighting designs involve new ballasts. Because ballast technology is constantly ...

The National Electrical Manufacturers Association (NEMA), Rosslyn, Va., recently created the NEMA Premium Ballast Program. According to NEMA, the program's goal is to provide a method of ...

STMicroelectronics L6585 integrates a power factor corrector with a half-bridge controller and all the relevant drivers and logic for an electronic fluorescent lamp ballast. STMicroelectronics L6585 ...

Fluorescent light fixtures are more efficient and cheaper to run than incandescent. But some fluorescent fixtures buzz or hum, and they take a long time to start when temperatures fall much below ...

An electronic ballast, in simplistic terms, takes a mains supply and transforms the energy to a storage capacitor, which in turn powers a half bridge to provide frequency-controlled power for a ...
