HID lamps are typically used when high levels of light over large areas are required, and when energy efficiency and/or light intensity are desired. These areas include gymnasiums, large public areas, warehouses, movie theaters, football stadiums, outdoor activity areas, roadways, parking lots, and pathways. More recently, hid bulbs especially metal halide, have been used in small retail and residential environments. HID lamps have made indoor gardening practical, particularly for plants that require a good deal of high intensity sunlight; HID lamp are a common choice of light source for marijuana growing operations. They are also used to reproduce tropical intensity sunlight for indoor aquariums. Ultra-High Performance (UHP) HID lamps are used in LCD or DLP projection TV sets or projection displays.
Most HID lamps produce significant UV radiation, and require UV-blocking filters to prevent UV-induced degradation of lamp fixture components and fading of dyed items illuminated by the lamp. Exposure to HID  bulbs operating with faulty or absent UV-blocking filters causes injury to humans and animals, such as sunburn and arc eye. ManyHID lamps are designed so as to quickly extinguish if their outer UV-shielding glass envelope is broken.

   HID bulbs are used in high-performance bicycle headlamps as well as flashlights and other portable lights, because they produce a great amount of light per unit of electricity. As the hid bulbs use less than half the power of an equivalent tungsten-halogen light, a significantly smaller and lighter-weight power supply can be used.

   HID lamps are also used on many general aviation aircraft for landing and taxi lights. For guangzhou fuchw indutstrial co., ltd
