<p>Solenoidal electric field lamps are effectively dimmed with no loss in lamp efficiency by powering the lamps with high frequency current pulses and periodically interrupting the current pulses in a time ratio fashion in order to reduce the average power being supplied to the lamp. The lamp may be dimmed from 100 to 0 percent of full power in an efficient manner as long as the pulse interruption period is less than the plasma deionization time of the lamp.</p> |
