Abstract:
1. A capacitor assembly comprising: (a) a housing defining an interior cavity along a longitudinal axis; (b) a base capacitor adapted to provide a first level of operating power to an HID lamp; (c) two or more secondary capacitors adapted to selectively increase or decrease operating power relative to the first level of operating power; (d) the base capacitor being larger in capacitance than any of the secondary capacitors; (e) the base capacitor and each secondary capacitor being positioned in the cavity, wherein the base capacitor occupies substantially all the volume at one end of the cavity generally long the longitudinal axis and the secondary capacitors are positioned in the remaining volume towards the other end of the cavity generally along the longitudinal axis; (f) further comprising electrical conduits between each capacitor and an electrical connection interface on one side or portion of the housing allowing selective individual electrical connection to any or all of the capacitors in cavity.
