Abstract

An electric bubl holder (9) with a funnel shaped corrugated shade attached to it, has an inverted cup shaped portion through which passes the electric cable (8) and in the top of which is housed the block (5, 6) which holdes the cable and the bulb (14), the lower cylindrical portion (3) having external threads (4) to screw into the open part of the cup. A serrated locknut (10) screws onto the lowermost threaded portion so as to lock a sloping corrugated adaptor ring (12) against the inside of the corrugated shade (11) to secure the shade in position.
