ABSTRACT:
In an electronic ballast for fluorescent lamps, means are provided by which the lamps are powered at their normal level whenever power line voltage is initially connected to the ballast. However, if the power line voltage is disconnected and then re-connected within about two seconds, the lamps will be powered at a lower-than-normal level; which lower-than-normal level will remain in effect until the power line voltage is once again disconnected and not re-connected until more than about two seconds have passed.
