Abstract
Holding current circuits in light sources controlled by a dimmer are operated in a coordinated manner to maintain proper operation of the dimmer without wasting energy. A plurality of light sources each including a separate holding current circuit may be controlled by a dimmer. The holding current units are selectively disabled and/or a maximum holding current drawn by the holding current units are selectively adjusted to maintain a desired current draw.
