This is the first MV lamp with additional metals to improve the poor color rendering index of clear MV lamps, by adding additional spectral lines to the spectrum.
There was also a spectral lamp that used these three elements.

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.

Interesting to see how the Zinc red line is quite weak. I think Cadmium has a red line too. This just seems to be the spectra of all three elements with some Plankian continuum from the hot electrodes and arc tube.
Do you have a picture of the lamp this spectrum belongs to Stan?

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

The problem with the Hg-Cd-Zn lamp, was that the pressure of the cadmium and the zinc was insufficient, and also they were very corrosive toward the quartz, rendering the lamps useless after a short time of operation.

I didn't know that this is a short-arc lamp. So why the mercury visible lines in this lamp, aren't wide as the common HBO with mercury only (I've seen spectrum of HBO lamps, in a stage lighting on an entertainment stage of the last independence day of Israel. The lines were much wider than in this picture).
