Editing Flashlight (section)

== HID ==
A less common type of flashlight uses a [[high-intensity discharge lamp]] (HID lamp) as the light source. An HID gas discharge lamp uses a mixture of [[metal halide]] salts and [[noble gas]] as a filler. HID lamps produce more light than a traditional incandescent flashlight using the same amount of electricity, though not as much as high power LEDs. The lamp lasts longer and is more shock resistant than a regular incandescent bulb, since it lacks the relatively fragile electrical filament found in incandescent bulbs. However, they are much more expensive than incandescent, due to the [[Ballast (electrical)|ballast]] circuit required to start and operate the lamp. An HID lamp requires a short warm-up time before it reaches full output.
