This paper deals with the stress which arose in outer glass bulbs of mercury discharge lamps during lighting. At their uses bulbs were irradiated by ultra-violet ray from inner discharge tudes made of fused silica and cooling water flowed around outside the bulbs.<br>Two kinds of glass bulbs, namely of Pyrex type borosilicate and 96% silica glasses, were examined.<br>Severe tension stresses concentrated at the inner surface were observed photo-elastically, and compaction (density increase) of glass in the same surface layer was also recognized. By heating up, the stress began to release itself at comparatively low temperatures; for borosilicate glass about 250°C and for 96% silica glass about 600°C. By irradiation of a glass test piece with a mercury discharge lamp, experimental reproduction of concentrated surface tension was possible.<br>Although the stress seems to result from compaction of glass by ultra-violet irradiation, photo-chemical, structural or atomic interpretations are not given now.
