A arc discharge light pipe comprised of a sapphire light pipe, a cathode, and an anode. The anode is a hollow cylinder with an end cap having an aperture therein. The pointed cathode and the end cap of the anode form an arc gap which produces a conical arc discharge. The light from the conical arc discharge passes through the aperture into the hollow anode. The sapphire light pipe is positioned inside the hollow anode to collect the light and focus it on a desired point.
