Lamps and Capacitors fail at a much higher rate than ballasts, I always test the capacitor for proper operation before anything else, if the capacitor is going bad a lamp will sometimes intially light and may hold for up to an hour before shuting down. Its too easy not to assure the capacitor is OK. This is our breakdown for the last year of HID service calls, 67% Lamps, 26% Capacitors, 7% Ballasts. We have only had 1 callback within 120 days form intial service. Hope it helps....
