An electric lamp comprises a lighting module, a pin comprising an electric contact for powering the lighting module, and an insulating sleeve surrounding the pin and movable along the pin between a covering position and an uncovering position. Further, the sleeve covers the electric contact of the pin when in the covering position, and is retractable against the action of a biasing means to the uncovering position, in which the sleeve uncovers at least a portion of said electric contact of the pin. |
