Tube as a desk lamp

AudioGeek · 31st January 2006, 03:37 AM

I am looking for a large unusual shaped vacuum tube with visable filaments to be used as a desklamp.

probably over 50W filament power.

any ideas on tubes?

Thanks!

I don't know any tube suggestions but I think it'd be best if you picked a large and cheap one. Since an incandescent lightbulb is basically a tube, you can mod the tube by putting in your own filament, fill it with an inert gas like helium, seal it to your liking, and walah! your own custom tube lamp.

How about one of these - a pre WW2 Brit Silica Valve (triode)

I happen to have some ER21A that are gas filled thyratrons. I tried to lit them, but the light is so small it's not noticeable

Also they have blackened glass.

a tube is a device, not a light bulb.....using it that way, kills it.........

even if it looks so nice......

Here's another way to do that. Every bit as easy, and uses hydrogen instead of helium. Actually gave this one a go, and it works great.

Clicky

See if you can blag one of Eapavant's mercury rectifiers:

Watch out for the UV though

i really don't care about practicallity. i really don't care if the tube is bad... just that the filament is ok.

i could even parallel some tubes i guess.

i am just looking for something that looks unusual.

thanks for input so far though!
