METAL HALIDE LAMPS
For use with fresnel style fixtures.
Wolfram Tru-Arc double-ended lamps are specially processed during
construction to extend lamp life and ensure arc stability. Each individual lamp is also computer-analyzed for the proper chemical fill, guaranteeing the color temperature and operating characteristics to be the most consistent in the industry.
