Lamp-circuit capacitors in Berson UV panels work hot and continuously and are a routine wear item. A capacitor that has drifted low shows as a lamp that strikes unreliably, runs below rated output, or trips on ignition — symptoms easily mistaken for a failing lamp. Check the value printed on the can against the rating below before ordering. Series number 87CAV009. This is the 33 µF value in the same 87CAV family as the 5 µF 87CAV004; the related 33 µF capacitor supplied with a bleed resistor is stocked separately under item 10178-1110.
