Here you can see two very old and unique Lamps with Glass lens in the crown for the use in light pens. A lightpen is a small light in the form of a pen that takes two AA Batteries and a single 3.5V E10 (MES) incandescent lamps. Both lamps here are of British origin and were made in th 1930s I would guess. The base of the upper one is bras, the bottom one has a nickel plated base. Both lamps are from a unknown manufacturer and rated 3.5V. Penlight lamps often had a flat design with a white glas reflector like on the upper one. Also only clear lamps are known. All pen light lamps have a s shaped filament out of straight tungsten wire, these too. These were the only lens typ model I know of wich makes them very unique.

Especially the bottom one would be used for a specialized application. The lens on that on is made out of blue colored glas wich makes a daylight colored beam. Im quite sure that that would be used in a penlight in a hospital or other medical atmosphere. Also clearly to not is the selfing region from the blue and transparent glas wich is a white line (Colored glas actually) in the glas.

Those are very unique, I once saw a simular lamp which was used on an electric comb for making hair grow, of cause it never worked but that little bulb was placed on one tooth of comb and the other on next tooth, a battery was in the handle which powered the comb 1930s and from Germany or Japan.

Interested in the history of electric lighting and incandescent in particular and neon glow lamps.
