Metal Halide lamps provide bright, white light. The 65-80 CRI helps bring out colors and textures, while improving visual acuity. Super Arc Metal Halide lamps, available in clear or with phosphor coating, have an average life of 10,000-20,000 hours. The compact arc size of Super Arc lamps improves the lamps' effectiveness, continuing the Litetronics tradition of producing the highest quality lamps available.
