What an interesting lamp! Perhaps a test model built for development and characterization purposes.

A nice engineering sample here

Pretty, please no more Chinese failure.

Most unusual! It looks as though the bulb may be air-filled, or do you think the cement makes a proper seal to the glass and it might be nitrogen filled? I suppose it might not be so old (before 1980s) because the arc tube seems fairly small - perhaps about 150W rating?

I think that this lamp is relatively new -- at least 1990-2000 years... Glass jacket definitely hermetic weakly or has nitrogen as You said.
I guess that arc tube is more powerful -- at range 250W because I have 150W MH lamps and arc tubes in these lamps are smaller.

Usually MH arctubes loses their output, when exposed to air, and the moly seals oxidizes and fail.

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.

If you have a small Tesla coil it could be possible to ionise the gas filling and check if it is air or nitrogen.

The seals of this arc tube are so long that I do think it could run in air for quite a long time.
