A hand held UV lamp and beam generator has resistive ballast provided by a glowing wire and thermal ballast provided by heated air coming via the same hot wire. A detachable reflector housing has curved symmetric spars in a generally parabolic shape defining an axis with an elongated axially lamp at a focal line. Heated air flows through the spars heating the lamp in a start mode and cooling the lamp in a run mode. The lamp and beam generator is made from electrical components found in a household hair dryer.
