Abstract
A fluorescent lamp unit including an adapter which contains a ballast, a fluorescent lamp electrically coupled to the adapter, a compressible gasket member and a jacket. The jacket is adapted to be easily removed from the unit upon failure of the fluorescent lamp. An inwardly protruding ledge which extends radially around the interior of the jacket provides a bearing surface for contacting the gasket member. Preferable, the lower portion of the jacket member is provided with a pair of diametrically opposed grooves for engaging a pair of lugs formed in the housing of the adapter. Preferably, each of the grooves has an offset portion and a stop for locking the lugs in place and thereby preventing rotation of the jacket member with respect to the adapter until the gasket member is compressed.
