A '''light tower''' is a piece of mobile equipment which has one or more high-intensity electric lamps and a mast. Almost always, the lights are attached to the mast, which is attached to a trailer, with a generator set to power the lamps. Normally the lamps are [[metal-halide lamp|metal halide bulbs]] and the generator is powered by a diesel engine. However, battery-powered, solar-powered and hydrogen-powered sets are available; light towers with [[electrodeless lamp]]s lighting are also sold. Modular kits permit separation of the generator set, trailer, lights and mast from each other. Another variation is an inflatable mast.<ref>{{cite web|url=https://patents.google.com/patent/US7198538 |title=Patent US7198538 - Inflatable figure assembly - Google Patents |publisher=Google.com |date= |access-date=2013-02-07}}</ref> Particularly when an inflatable mast is used, the lights may be placed close to the ground, with a reflector attached to the mast.<ref>{{cite web |url=https://patents.google.com/patent/US7621650 |title=оЮРЕМР US7621650 - Light tower, light tower support, method for operating a light tower and a ... - Google оЮРЕМРШ |publisher=Google.com |access-date=2013-02-07}}</ref> When soft lighting is wanted, an inflatable "balloon" diffuser may be used. An inflatable mast may serve as a diffuser.

Light towers are used when illumination is required but not otherwise available, both outdoor and indoor, usually temporarily. Example activities are [[construction]], mining, motion picture production, demolition,<ref>{{cite web|url=http://www.willburt.com/products/light-camera-towers/night-scan-powerlite/ |title=Night Scan Powerlite &#124; The Will-Burt CompanyThe Will-Burt Company |publisher=Willburt.com |date=2013-01-18 |accessdate=2013-01-28}}</ref> emergency services, sport or agricultural sectors.
