ABSTRACT:
Lamp housing which, in one form, selectively receive different sized P.A.R. lamps and, in another form, selectively receive a P.A.R. lamp or an incandescent lamp. In either instance, the P.A.R. lamp is retained in position by spaced-apart flexible latches which engage a portion of the lamp lens. Additionally, and in order to provide ventilation space between the inside of the housing and the positioned P.A.R. lamp, spacer arrangements are provided. In both housing forms, ventilation openings are provided at various locations in the housing. As an added feature, each housing form, which includes a mounting bracket, is secured in an operative position by a support clamp. The latter is unique in configuration, being defined by a first and second portion at right angles with respect to each other and an arcuate third portion. The support clamp is typically received onto a truss or the like by fastening means extending through the arcuate third portion, where the latter is threaded at preselected locations to achieve versatility in housing placement.
