Abstract
A compact fluorescent lamp having a lamp envelope with a plurality of lamp ends disposed within a housing or base configuration, utilizes an enhanced adhesive material for securing the lamp envelope to the housing or base that is reflective. The adhesive material has a reflective material added thereto that allows for the light typically absorbed or otherwise lost in the housing, to be reflected back out thereby improving the luminous efficiency of such lamp. The adhesive material is also effective for blocking UV radiation from entering the area in which electronic components of the ballast circuit may be disposed.
