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 purposes achieve higher efficacy by developing high end temperatures without excessively obstructing the transmission of light and without creating excessive thermal losses through radiation and conduction. To reduce the obstruction 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 constructed 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/cm<2> and with an arc loading from 60 to 150 watts/cm.
