A mobile light tower 1 comprising a base unit 2 and at least one light 4a, 4b connected to the base unit by an extendable mast 5. The base unit including a power source for powering the at least one light 4a, 4b, the extendable mast 5 adapted to move between a retracted position (Figure 2) and an extended position. Wherein the mobile light tower includes a controller 6 and a wind speed sensor 7, the controller being adapted to lower the extendable mast 5 to an intermediate position, between the retracted position and extended position, when the wind speed sensor 7 determines that a predetermined wind speed is exceeded. Optionally a light rig 14 is present to provide a mounting point between the lights 4a, 4b and the extendable mast 5. Preferably the extendable mast 5 is telescopic and the wind speed sensor may be mounted distal from the base unit 2. |
