ABSTRACT:
A metal vapor discharge lamp has an envelope formed of a vitreous high temperature resistant material. A pair of electrodes each has a metal rod and an arc supporting electrode. The metal rods are sealed at one end of the envelope. The envelope is filled with a starting gas and a charge. The present invention also includes insulating films formed on the envelope behind the arc supporting electrodes to increase the vapor pressure of the charge, and improve output and the spectral color distribution.
