ElectronicHID ballasts
-- Plant Engineering, 1/15/2008
e-Vision® electronic HID ballasts include circuitry for self-heating thermal protectors for 70- and 100-W metal halide downlight applications. The ballasts feature an auto shut-off mechanism for lamps operating in a questionable thermal environment due to misapplication or failure of thermal protector heating elements. Lamp wattage regulation optimizes lamp color quality over life and reduces lamp-to-lamp variations, while the unit’s electronic circuitry offers opportunities for energy savings, cost reduction and design flexibility relative to magnetic HID alternatives.
