Abstract: A cold temperature light fixture comprises an insulated housing having one or more ballasts and plural lamps to retain heat within enclosure so that ballasts and lamps start up more rapidly, and greater light output is obtained. The fixture may be operated in selected configurations and may include secondary heating elements within the fixture to warm ballasts. In one operating configuration, one or more of the ballasts is always energized and one or more of the lamps is preferably at least partially illuminated in an off mode. A sensor is operable to switch the fixture between the off and on mode, in which all ballasts are energized and all lamps illuminated.

Abstract: An integral backpack/upper body garment comprises a garment to which a split backpack is attached or attachable to the back panel of an upper body garment. A front backpack assembly including front assembly with shoulder straps is attached/attachable to the front face of the back panel, and a rear backpack assembly including storage compartments is attached/attachable to the rear face of the back panel. A circumferential garment compartment has two walls, one attached to the front assembly and one attached to the rear assembly. The jacket may be rolled up or folded into the garment compartment and the two walls joined by a closure to protectively enclose the garment therein when it is not worn. The backpack may be worn with or without the integral jacket, and the jacket may be worn with or without the backpack.
