ABSTRACT:
A high-pressure sodium vapor discharge lamp of improved color including in combination a specified arc length to power input, a predetermined sodium to mercury amalgam ratio, heat shields surrounding each end of the arc tube and an improved end cap to arc tube seal, which combine to increase the sodium vapor pressure and provide a lamp of greatly improved color.
