ABSTRACT:
In a double-socket electric lamp containing a low-voltage halogen light source to fit in a secondary socket of a commercial supply voltage controlled by a transformer device to fit in an existing primary socket for a commercial power source; the double-socket electric lamp comprises a root inserted in the secondary socket, the root having an indentation in a position opposed to a projected electrode at the bottom of the secondary socket, and an electrode formed in the indentation that comes in contact with an end of the projecting electrode of the secondary socket. The transformer device for the double-socket electric lamp containing a low-voltage halogen light source comprises a primary base to fit in an existing primary socket connected to a commercial power source, a transformer for decreasing the commercial supply voltage to a voltage suitable for use in the double-socket electric lamp, and a secondary socket to fit on a root of the double-socket electric lamp, having a projecting electrode fixed therein; the projecting electrode of the secondary socket being in contact with an electrode in the indentation formed in the root of the double-bulb electric lamp.
