The Winco mobile light tower is a compact trailer mounted telescoping mast and genset. At the top of the mast are six of our outdoor flood round heads with a 1000 watt lamp each. This unit has an onboard engine and fuel supply to run for 6 hours. It also has a male L21-30 panel mount connector for power input. This allows you to run the light tower off of shore power when the power is available and the noise of the Genny is not desired.
