Abstract: In order to provide a temporary lighting solution in extreme weather or lighting conditions, this application has been conceived. A set of blowers will continuously operate to inflate a long cylindrical tube in which a light has been placed to illuminate a designated area. Because the unit may be used outdoors a stabilizing rod has been placed in the event of a sudden loss of power to prevent the tube from deflating rapidly and descending rapidly to the ground level and causing possible injury to persons on the ground or the light itself. Because this device may be used in extremely windy conditions, a plurality of outriggers will attach to the frame and extend outward to stabilize the device, when needed. Because the blowers will operate continuously and thereby produce noise a plurality of noise abatement containers are placed around the blowers to help lessen the noise level.
