Abstract
Incandescent lamps having an improved light source are disclosed. The light source contains a halogen compound along with a fill-gas at a pressure above atmospheric. The light source has an oblate ellipsoidal shape so as to obtain a desired temperature gradient which reduces typically experienced 'cold spots' that detrimentally contribute to the condensation of halogen compounds within the light source which would otherwise reduce the desired light output of the light source throughout life. Also disclosed is a method of manufacturing the light source.
