Abstract: A light tower includes a generator assembly including a prime mover, an alternator operably connected to the prime mover, the alternator configured to produce alternating current electrical energy, and a rectifier operably connected to the alternator and configured to convert alternating current electrical energy produced by the alternator to direct current electrical energy. At least one light emitting diode matrix is electrically connected to the generator assembly by an electrical connection, and a regulator is operably connected to the alternator and configured to detect a current of the direct current electrical energy in the electrical connection. In response to a detected current of the direct current electrical energy in the electrical connection, the regulator controls the alternator to adjust the current supplied to the at least one light emitting diode matrix.
