The invention relates to a lamp, in particular to a novel energy saving double-end iodine-tungsten lamp. The novel energy saving double-end iodine-tungsten lamp comprises a lamp holder, a lamp tube, a lamp filament and molybdenum plate assemblies, wherein the molybdenum plate assemblies are arranged at the two ends of the lamp tube; the lamp filament comprises two light emitting bodies, a connecting body and filament tails, the connecting body is arranged between the two light emitting bodies, the filament tails are arranged at the two ends of the lamp filament, a dented pit is arranged in the middle of the connecting body, and the projecting part of the pit is in contact with the lamp tube. The whole lamp filament is supported and prevented from sagging through the arrangement of the pit in the middle of the joint of the lamp filament and the contact arrangement of the projecting part of the dented pit and the lamp tube, and holder rings are not arranged; besides, as the whole lamp filament is molded once, the whole procedure of winding the holder rings is saved, the holder rings do not need to be burned concave one by one, the purposes of energy saving and environment protecting are achieved, and the production efficiency can be improved. The novel energy saving double-end iodine-tungsten lamp has the advantages of skillful structure, energy saving, environment friendliness, high brightness, long service life, simple technology and the like.
