Abstract
A significant reduction in thermal energy loss along the legs or ends of the arctubes in a CMH lamp is achieved in the present invention. The diameter of a mandrel ( ) is significantly reduced for CMH lamps. Either a single overwind ( ) or multiple overwind layers ( ) are used. Since the thermal conductivity of the mandrel greatly exceeds that of the overwind, the axial thermal conductivity will scale like the cross sectional area of the mandrel alone.
