Abstract
A light fixture of the type enclosing a plurality of standard dry cells. An outer, support member forms an outer housing to be affixed to a wall, ceiling or other fixed object. The outer housing receives an inner housing comprising a unitary battery enclosure, reflector and lamp socket receptacle. A sheet of resilient foam material disposed between the outer and inner housings is compressed upon assembly of the two members and urges them apart to aid in separating the members when latches are released. A dome-shaped lens attaches to the inner housing to protect the lamp and to diffuse the light which it produces. The enclosures for the batteries which are formed by the inner housing are provided with partitions separating the batteries, and upstanding bosses about certain of the contacts therefor, to prevent completion of an electrical circuit should any of the cells be reversed during installation.
