METAL HALIDE LAMPS

The lighting system of the LT12 Series Light Tower is comprised of 4 metal halide, 1000-watt lamps.These lamps provide maximum illumination with typical lighting coverage of 5 to 7 acres.The lamps are controlled by individual circuit breakers for versatility.

ENGINE

The LT12 Light Tower is powered by a diesel engine that is equipped with automatic shutdowns for low oil pressure, high coolant temperature, and alternator charge failure.

STABILITY

The light tower can be raised vertically in excess of 31.5 feet (9.6 meters) by means of a manual winch. The tower tensioning system is designed to provide the necessary tension to safely control the pivot of the tower. The light tower has a wind stability of up to 65 mph with outriggers and jackstands fully deployed.

PANEL LIGHT

A panel light automatically illuminates the control panel and all functions when the engine access door is opened. This feature is convenient for night deployment.
