I got this lamp bulb in a box with other electronic components from a old timer who wanted to not throw them to bin but to pass along. A lot of resistors I got from him as well, if you remember. Haha.
I have 2 variable power supplies:
The famous STP3005 which is a DC 0-30V and the vevor variac 0-330AC both bench supply.
So I have good means to test this component !
My original thought is to put it directly to the DC power supply, and ramp up the voltage until I can see something is happening with the component. THen, if the component is not DC, I will use my AC variator and ramp up with it at a much higher voltage than the DC one. If I add a rectifying bridge to the AC variac, I can power up with DC voltage way over the limited 30V of the STP3005.
But before doing anything, because I sincerely dont know anything about this type of lamp, I think is best to ask first and do later.
By looking on the metal inscription, it says 120 in the middle, but no AC or DC. It assumes you have to know it already. Or that is the number of the component production. Who knows. Its the only hint I can get from it. Nothing else.
My best Guess, this is a lamp used in old photo blitz, but those big ones, not incorporated into the photo aparat. 'External blitz vintage' is what I searched for, to show you this image here. I know it because my father used a couple of them and if I remember right it was using this kind of lamp bulb, or very similar. But this is the closest idea I may have about this kind of lamp. I may very well mistaken about it.
- My question to you, is how I can make it work? How should I proceed?
Thank you !
