Gen sets and light towers
Most diesel-driven, portable light towers have the same basic components – a diesel engine and generator in a trailer-mounted enclosure, a winch-operated mast and floodlights. Ask these questions on your next job to narrow down your selection:
How much light is needed? Know the size of the area needing illumination, whether light needs to be constant and how bright it should be. Experts at your local dealership or rental store can then determine the recommended number of foot-candles for the application based on standards from the Illuminating Engineering Society of North America – and ultimately how many light towers are required.
Does the job require light and power? If yes, choose a light tower that provides both.
How long will you need light? Fuel capacity should be a key factor in selection. Large, efficient fuel tanks translate into longer run time. Some light towers offer 52 or more hours of light. Depending on site conditions, an optional auto start/stop feature provides consistent and automatic illumination run time.
