Commonly used for industrial and commercial purposes as the lighting produced is high output, making these metal halide type lamps a powerful and efficient light source. This type of lighting produces an almost white light with excellent colour rendering properties. Although one of the most expensive types of lighting, this is one the most energy efficient giving roughly 8 times the light output, a 50w lamp is roughly the equivalent of 400w of incandescent light and will last for at least 6,000 hours.
The metal-halide lamp produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides. It is a type of high-intensity discharge (HID) gas discharge lamp with improved efficacy and color rendition of light.
Metal-halide lamps have high luminous efficacy of around 75 - 100 lumens per watt which is about twice that of mercury vapor lights and 3 to 5 times that of incandescent lights and produce an intense white light. Lamp life is 6,000 to 15,000 hours.
