ABSTRACT:
A recessed lighting fixture having a socket for receiving a lamp which generates light for emitting through an opening in the fixture. The socket connects to electrical conductors that communicate through a ballast with a supply of electricity. An insulative bag encloses the ballast and a banding tape seals an opening of the bag around the ballast for restricting communication of heat from the lamp to the ballast during operation of the lamp. A deflector plate disposed between the socket and the ballast further blocks communication of the heat to the ballast. A method of restricting thermal communication with the ballast is disclosed.
