Abstract
An arc lamp having a sealed lamp tube with electrodes to either side of a septum. The septum extends through the length of the arc chamber. An emissions chamber extends from the end of the arc chamber without the septum. A window at the end of the emissions chamber is displaced from the end of the septum and from the arc chamber itself by a sufficient distance so that magnesium diffusing from the electrodes does not darken the surface. The magnesium electrodes are slugs encased within high temperature cells open at one end.
