TOUGH PINT-SIZED LAMP

CD 1964038 E&MP26.025

Electric Light

June 15, 1936

Shows new medium bi-post lamp (left) and special socket (bottom) designed to accommodate metal prongs.

This pint-sized lamp is not only much smaller than the present 1000-watt mogul screw-base lamp (right) but can be burned out in the open where its hard-glass bulb is immune to breakage from sudden temperatures changes caused by contact with rain, sleet, snow and the cooling smear not infrequently left by light-dazed insects which have hurled their juicy bodies bulbward.
