ABSTRACT OF THE DISCLOSURE A portable electric lamp. The lamp has a body including a lens, a lens holder, a reflector, and a bulb holder connectable through a switch with a source of electric power. A translucent diffuser sleeve is co-axial with and surrounds the bulb holder. The sleeve is asso- ciated with a drive so that it may be moved axially relative to the bulb holder between a retracted position at which a bulb held in the bulb holder is arranged to direct a spot beam through the lens and a forward position at which light from the bulb is diffused by passage through the diffuser sleeve. The lamp can provide a beam of light and a spread of light for local work. It is particularly useful in mines. It may be mounted on a cap or safety helmet or held in the hand.
