    Those are beautiful looking tubes all lit up. I have a pair of 6895 mercury vapor tubes (the largest one on the left) and I can only wish I had the knowledge to get them to light up. I bet they'd make a great looking night light. c4n46gg89qdi.jpg

    That is a big tube, it probably needs 5 volts and 10 amps on the filament.

    Ok then; now how does one go about making steampunk night lites out of them? I'd love to see them lit up.

    Well, you need a transformer with a 5.0 V @ (better than ) 10 A secondary. Probably not hard to find.
    The anode needs 20 VDC to ionize the mercury, apparently.
    You'll want to wear sunglasses to attenuate the UV produced by the mercury plasma -- although the glass envelope of the rectifier itself should help. The spectral line at 254 nm is intense (especially at low pressure).

    Thank you for the detailed advice. Now there's a little voice in my head telling me that I should not attempt this and enjoy those works of art as they are.
    Installing a kt88 one pin off is still fresh in my memory. That got my attention as the tube started vibrating, instantly turned green and then let the magic smoke out of the amp. Yes I'm thinking I'd be wise to listen to that little voice.

    That's a great pic, Scott B) Does this mean you have finally fired your vinyl system back up?

    Light a normal vacuum tube's filament - safer and easier. Even better: put a string of tube filaments in series and use it on your holiday tree. :) Maybe use an isolation transformer, just in case. The filaments will get warm but not hot -- in most tubes, any way. :)

    ... another easy way to get cool visual effects -- get (or make*) a plasma ball. :)

    Probably goes without saying that our son took that photo, albeit a long, long time ago. :)

    We still have the plasma ball; it's in the basement. Imagine that?! ;)

    _______________
    * see, e.g., https://www.instructables.com/Make-a-Plasma-Globe-out-of-a-Light-Bulb/ It's not exactly hard, but not quite easy, either. ;)

    Hehe, unfortunately, Jody, that's just a poseur pic from a while back, probably back from before we started talking about those cart searches!

    I wouldn't use Mercury rectifier tubes as a night light, to easy to bump into and break. It would be a lot easier and safer to use a voltage regulator tube like an OD3 or something like that.

    Good call. The "glow discharge" voltage regulator tubes are filled with one of noble gases (argon, krypton, neon, perhaps others) which are benign (in fact, more or less chemically unreactive).
    I had to look up what gases these "cold cathode" tubes use :p so I cannot guarantee the accuracy of this -- but it sounds about right.

    Pretty pictures, too :)
