More sophisticated ballast designs detect cycling and give up attempting to start the lamp after a few cycles. If power is removed and reapplied, the ballast will make a new series of startup attempts. Another phenomenon associated with HID lamp wear and aging is discoloration of the emitted light beam ("fading" [14]). Commonly, a shift towards ...
