ABSTRACT:
The double-ended lamp has a base at each end, one of which is connected to cable. To prevent scattering of the high-pressure lamp bulb in case of explosion for example due to improper handling before installation, it is enclosed within a transparent protective tube, secured at its ends by caps slipped over the respective bases. To hold the caps and hence the tube in place, and prevent rolling of the bulb enclosed by the tube in the tubular end caps, the connecting cable is passed out of one end base from the side and it is of such length that it can be stretched adjacent the tube enclosure of the lamp to the other base, to be there fastened by a cable connector to the base pin terminal by a wing nut, or the like.
