Abstract
A high-pressure mercury vapor discharge lamp including halide additions. The lamp comprises, next to mercury and a rare gas, one or more of the halogens iodine, bromine and chlorine and furthermore sodium, thallium and possibly indium. The lamp comprises calcium in the form of calcium halide which emits in a broad band in the red part of the spectrum. Cadmium may replace part of mercury. The lamp may comprise as extra additions one or more of the elements scandium, yttrium, lanthanum and the lanthanides.
