These bulbs produce a high lumen output for bright light in commercial settings like street lights parking lots or warehouses. The luminous flux φ v in lumens lm is equal to the power p in watts w times the luminous efficacy η in lumens per watt lm w. The metal halide lamp is an ac power source that produces an arc discharge luminous discharge lamp in a mixed vapor of mercury and a rare metal halide. What is hard to cross in is that metal halides actually start out at very high efficiencies.
