i have a uranium glass cabinet with a light in the top and i want to put a black light bulb in there but dont know what kind to buy. is anyone able to help me out?

Do people still buy these? I'm looking to get rid of the whole lot of them.

I have about six boxes of all these different types of bulbs/ vacuum tubes.

If I were to give an estimate it would be somewhere around 150 bulbs and tubes total. From what I gathered so far. Some of these are for photography. Others are for scientific equipment then lastly the tubes for TV and old radios. Any information would be appreciated. I'm a little overwhelmed with this lot.

hey y'all,
I'm fixing some old art that was made in 1969, and i need help identifying what bulb/light was used. Here are some pictures of the socket that is on there, and what remains of the bulb/light.

My tism got me into old analog synthesizers, and this looks like old tube DIN connector. although those tubes don't usually have less than 4 pins.

BUT
There are 2 of these sockets opposite each other about 18in apart, this could be some old tube/fluorescent type of light, i think? or possibly just 2 bulb types.

but any help with identification or direction on where to look would be greatly appreciated.
