Maglite is a brand of flashlight manufactured by Mag Instrument Inc, located in California. Constructed principally of anodized 6061 aluminium, they have a variable-focus beam. Maglites are produced in several colours such as black, silver, blue, and red with a selection of finishes. Original Maglite flashlights had either krypton or xenon incandescent bulbs, and the current product line is gradually transitioning to LEDs. Accessories include belt holsters, mounting brackets, colour and glass lenses, attachable fibre optics extensions, higher-powered incandescent bulbs, and LED conversion modules.
