Abstract
A starting aid for a metal halide lamp uses iodine and an inert gas instead of mercury so that the entire metal halide lamp may be mercury-free. The starting aid is a UV enhancer that includes a UV-transmissive capsule with a cavity in which iodine and an inert gas are sealed, wherein the iodine emits UV radiation when excited to reduce a starting voltage of the lamp.
