They are used to light large indoor areas, such as gymnasiums and sports arenas, and outdoor areas, such as car lots. Metal halide lamps are similar in construction and appearance to mercury vapor lamps. The addition of metal halide gases to mercury gas within the lamp results in higher light output, more lumens per watt, and a higher color rendition index than from mercury gas alone. Metal halide lamps have shorter lifetimes (5,000–20,000 hours) compared to both mercury vapor and high-pressure sodium lamps.
