A handheld lamp is disclosed wherein the light source is a rapid pulse unconfined xenon arc tube containing more than three atmospheres of xenon gas pressure, and providing a selectable spectral output of ultraviolet, visible, or ultraviolet and visible wavelengths. The lamp contains a radiation guide for directing the generating light, the tip of which is maintained cool for effective use such as in curing tooth restorative materials. The lamp may be located in the power supply and light delivered through a flexible light pipe.
