A transportable lighting system. The lighting system is designed to withstand the difficult and extreme weather conditions typically experienced in outdoor work sites such as drilling rig environments. The pulley and roller arraignments are designed for minimal friction. The overall pulley and roller design for the lifting of the unit (including the way the cables are orientated) is extremely robust. The outrigger includes fold out and lock in place design. The power source can run a duel transfer switch setup powered by an external supply (like drilling rig power) or from its own 100% back-up generator. Lighting used is typically light in weight and bright. Towers are skid mounted and mobile, e.g., with the use of a truck. Individual lights can swivel and tilt as can the entire bank of lights.
