HQI is a high temperature quartz iodide bulb, which is a double-ended metal halide bulb. There are two types of metal halide bulbs, one is a single-ended bulb, and the other is a double-ended bulb. The first type of bulb is a bit like the bulb of a traditional table lamp. These bulbs have an inner liner for light, and the outer layer is actually a protective cover. In addition to the function of preventing the inner layer of the bulb from bursting, it actually has an important function of eliminating invisible short-wave ultraviolet rays emitted by the inner liner.
