Thread-topic: [TCML] 4 inch xenon and krypton tubes wanted for Halloween display
I have a Philips CX 900Xenon arc lamp from a projector, possibly unused, it's hard to tell, it may or may not meet your needs, but it looks cool. Right now it's on ebay, but if you contact me directly I can certainly give you a discount as a "friend from the list" - it is government surplus from an artic circle (or above) ground station. I don't know how it was used, whether in a projector or in some other application. To avoid putting auction links on the list, if you want to see photos, look for "Philips CX 900 Xenon" (with quotes) on ebay and you will find the listing and it will show you pictures.
Regards, Bill

I was mistaken about the pressure fill lof 10 Torr on the xenon bulbs, instead it was 40 Torr. My memory at 64 must be lacking. I would imagine that 10 Torr which may be the normal fill for bulbs of this diameter and that 40 Torr would mean that less of evacuation of gas takes place.(more bulb gas resistance because of higher pressure?) I think that these bulbs were 30mm diameter, I could be wrong.on these aspects. Here's a short video of these polar discharges where I misquoted the top and bottom bulbs as being neon bulbs.

The actual load on the solid state 20 khz transformer was a set of aluminum foil capacitive plates with the xenon bulbs each attached to each plate as a one ended polar discharge. Problems developed where the glass degraded and formed cracks near the end electrodes, ruining them. I surmise that they should be suspended in such a way as to not allow high frequency currents to travel through the glass itself. Heres another video showing some wireless lighting of bulbs using the 20khz SSTTesla Secondary Effects from 20,000 hz SST Polar Tube Discharges.

In any case I hope some custom bulb manufacturer can be found, but I am beginning to think this will not happen. I particular like the use of 4 inch shorter bulbs for the lower ignition characteristics where Tony Greer had charged ~ $30.00 I have not found any bulbs like these on ebay. HDN

I formerly obtained bulbs from Tony Greer of Texas. He was ill the last time I corresponded several years ago. None of the local sign companies seem to carry those gas tubes anymore. A difficult item to find. Tony filled some of the xenon tubes at 10 torr, which would give a lightening like display when used from a solid state 20 k transformer. HDN
