The surveys revealed that high-mast lighting was by far the preferred method of lighting. [3] By 1967, Europe was known to have high-mast illumination technology in practice. 1968 saw the first permanent US installations of high-mast illumination starting in Auburn, Washington south of Seattle. The first American towers were 100 ft (30 m) tall ...

They are usually flat, without information about the light's direction, whilst some game engines use multiple lightmaps to provide approximate directional information to combine with normal-maps. Lightmaps may also store separate precalculated components of lighting information for semi-dynamic lighting with shaders, such as ambient-occlusion ...
The common high white strobe flashes 40 times per minute, at an intensity of 270,000 candelas for daytime, 20,000 candelas at twilight, and 2,000 candelas at nighttime. [1] Dual lighting is a system in which a structure is equipped with white strobes for daytime use, and red lights for nighttime use. In urban areas, these are commonly preferred ...

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 bulbs and the generator is powered by a diesel engine.
