Method and apparatus for assuring use of a fluorescent or similar high efficiency lamp in a screw base socket, the invention provides a circuit containing a screw base socket and an associated thermal sensing unit capable of interrupting power to the circuit on sensing of heat such as is generated by an incandescent or similar low efficiency lamp when mounted in the screw base socket. Practice of the method permits use of only fluorescent or similar lamping such as is incapable of sufficient heat generation to interrupt power to the circuit, the methodology of the invention preventing use of incandescent or similar energy inefficient lamping. The method and apparatus are particularly useful in the lamping of recessed downlighting fixtures.
