Arms Working elevators offer two types of light masts. On the one hand, a light mast fitted to manually moving tires. That light mast requires a standard outlet with a 16 A safety and has 4 x 400 watt throws. However, there is a larger light mast that has a harness and can be towed on a car. That light mast has a small generator that provides, in addition to powering the spotlights, a current of 5 kW. The lights on this mast are 4 x 1,000 watts.
