Metal halide light bulbs are high-intensity discharge (HID) lamps that offer excellent color rendering and high efficiency. They produce a bright, white light that is ideal for various commercial and industrial applications. Common uses for metal halide bulbs include outdoor lighting for sports fields, parking lots, and street lights, as well as indoor lighting in warehouses, factories, and large retail spaces. Metal halide lamps require specific ballasts and often have a warm up time to reach full brightness.
