Osram-GEC Experimental 240V 100W GLS lamp with single filament support

A number of these experimental lamps were issued to GEC staff and others in the lighting industry in 1979, to commemmorate the centenary of the invention of the incandescent lamp. The actual saving in production was so small however, that it did not proceed into mass production. http://www.lamptech.co.uk/Spec%20Sheets/IN%20WC%20GEC%20240-100PS60CL-BC%20Single%20Support.htm

Here is an extra low voltage incandescent lamp with a single support.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

That is interesting, James. This one overcame the length of the filament to use the 240 volts mains. Did they used thicker filament diameter for this construction?

Pretty, please no more Chinese failure.

What is it? A standard G.L.S. lamp with just one support instead of two? One way to reduce thermal conduction from the filament at the expense of overall fragility and mechanical shock resistance.

Manufactured articles should be made to be used, not made to be sold!

I say this belongs in my collection HA HA. But the photos would be nowhere near as good as James!
