Does anyone remember the little squat MES bulbs that had a lens blown into the glass at the top, for use in the Penlight-type torches powered by a couple of 1.5V HP7 batteries? I think I've still got such a torch somewhere, I used to use it when peering around in the back of equipment-racks to trace cables.
These are still available on ebay and elswhere.
Lamps for one or two dry cells are common, and those for three or four cells exist but are very rare.
Widely used by doctors who prefer the traditional incandescent lamp over LEDs.

A white plastic sealed disposable penlight is available for medical use that uses two AA cells and one of these bulbs.
