ABSTRACT OF THE DISCLOSURE Methods of and apparatus for coating the glass envelope and predetermined portions of the end caps o. a fluorescent lamp with coating of polymer.c material including securing the end caps against displacement, subsequently, preheating the glass envelope and the predetermined portion of the end caps to a first pre- determined temperature above the melting point of the polymeric material for a predetermined amount of time; subsequently, mask- ing the electrical connecting pins and all of the end caps except the predetermined portion thereof; subsequently, exposing the glass envelope and the predetermined portion of the end caps to a fluidized bed of powder of the polymeric material for a predetermined amount of time to apply a coating of the powder to the glass envelope and to the predetermined portion of the end caps; subsequently, reheating the glass envelope and the predetermined portion of the end caps to a predetermined temper- ature above the melting point of the polymeric material and for a predetermined amount of time to melt and fuse the powder on the glass envelope and the predetermined portion of the end caps to form the applied powder into a substantially uniformly thick coating of polymeric material and;subsequenly, unmasking the pins and the end caps and unsecuring the end caps. Additionally, the glass envelope and the predetermined portion of the end caps may be cooled after reheating to a predetermined temperature and for a predetermined amount of time to quench and clarify the coating of polymeric material.
