Cadmium Spectral lamp

Cadmium Spectral lamp

Philips manufactured spectral lamp containing Cadmium. Construction appears to be similar to a high-pressure mercury with a quartz discharge tube, but the electrodes are hidden from the main arc, possibly to reduce thermal emission in the spectrum. The outer envelope is evacuated.

Is this photo colour accurate? One of my subs on YouTube lit these recently, he is an Aussie I think, are you the same person? I can’t even remember the YT name, might be rustymotor.

Colour was tricky to capture accurately. This one seemed to be the closest out of a few I took. The others appeared bluer. The think the background is fluorescing a bit but it does appear duller and greener than a mercury. I haven't any YT videos up on this lamp so not me. I have a low pressure Cd lamp I will put up for comparison.

In most pictures of cadmium spectra lamps illuminated, that I've seen, the color was similar to this picture. I used to think that cadmium have less green color than high pressure mercury.

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.

Could you put a clear mercury lamp and this side by side so we can see the difference??

hmmmm, might give that a go. The trick will be matching the light output. The Cadmium light output is less than a similar mercury.

A note for the description that tuopeek put in his picture: The electrodes are behing diaphragms so their sputtering are contained inside them, so the arctube don't blackens during life.

It is running on a leak-transformer designed for 90W SOX sodium lamps. This seems to be the gear Philips suggests using with these lamps. Philips manufactured a selection of very desirable spectral lamps.
