General Electric MAZDA S-2 SUNLIGHT Sun Tanning Lamp
Lampe solaire à rayons ultraviolets
Sonnenlampe UV-Strahlung

This lamp, a small version of the 400W S-1, was launched by GE in 1932 for residential use.

The bulb contains a drop of mercury. When operated, the heating of the tungsten filament temporarily vaporizes the mercury and in the process gives off mainly ultra-violet rays, the same mild ultraviolet content as natural sunlight, while the bulb employed a specially designed glass to filter out the more harmful rays.

The purpose of the metal cap is to raise the temperature of the mercury pool and increase the UV output.
