HIGH PRESSURE METAL VAPOR DISCHARGE LAMPS OF IMPROVED EFFICACY ABSTRACT High pressure discharge lamps containing a fill of mercury and metal halides, having a power input of 250 watts or below and useable for general illuminating pur- poses achieve higher efficacy by developing high end tem- peratures without excessively obstructing the transmission of light and without creating excessive thermal losses through radiation and conduction. To reduce the obstruc- tion of light, heat-conserving coatings on the lamp ends are preferably omitted and small neck seals are used which serve also to reduce thermal losses. The lamps are con- structed with an aspect ratio of arc chamber length to diameter from 0.9 to 2.5 and with an electrode insertion factor from 0.1 to 0.6 and operate with a wall loading from 10 to 35 watts/cm2 and with an arc loading from 60 to 150 watts/cm.
