Abstract
A lighting fixture for a luminaire, such as that for an outdoor floodlight, has all of the electrical components for the luminaire, including the lamp socket, mounted on a tray that is removable from the fixture. The lamp socket is affixed to the tray at a location such that it properly positions a lamp inserted therein with respect to an optical system. By using standardized trays with various different ballasts and other electrical component variations, the same floodlight housing may be utilized for a variety of lamp types and power ratings.
