Abstract
An electronic-ballast lamp system comprises a modular lamp ballast in a plug-in housing. A light fixture has matching sockets for the ballast and is pre-wired for the intended lamp tubes. In one instance, an electronic ballast accepts 100-300 VAC and 50-60 Hz power inputs, and provides the correct rapid-start, instant-on, or standard lamp outputs as sensed from the lamps themselves, or as read from a data card embedded in the light fixture. The data card is read optically or electronically, depending on application, or the lamp types may be dialed-in on the ballast itself.
