IV27 tube clock

[Thomas Wildgen]

I found this out on Ebay,  it looks like something that I can add to a tablelamp, but I know nothing about them.

reliability? how long with it last? I found a site selling just the tube for under $10. 

Any help is welcome!

TIA,

Tom

They're a longer version of the IV-18 Soviet VFD tube. They'll last many years if the IV-18 is anything to go by. I remember when these were <$1 each.... how times have a changed!
