Xenon short arc

Xenon short arc

Click to view full size image

This XBO Xenon lamp might be my most dangerous lamp. Shown here briefly without it's ballistic cage. It has been used quite a bit judging by the condition of the anode. It requires a 30kV pulses to ignite but once struck has less than 100V across the arc. I have experimented and managed to build an ignitor but not the DC supply to keep it running. Not too sure I want to as it is rated at 2kW.

I bet the voltage is a lot lower then 100, more like 30, you could always use two car batteries and some booster cables, while it won't last long because that is a pretty large load on a battery at least you could see it working..

These lamps can explode like hand grenade also when cold.

I"m don't speak english well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I hope that LED won't replace all forms of other light

I tried 30V DC and it couldn't quite keep the keep the arc running, may have had something to do with the 30A limit right enough. Car battery might be worth thinking about if the current can be stable.

yes, dor123 they can even become more fragile as they age.

Large lead acids are pretty stable for a short run, and they did use Xenon short arcs in tanks, Collin has one on [url=http://www.lighting-gallery.net/gallery/displayimage.php?album=2828&pos=48&pid=86393] this page {/url} only they use a Tesla coil to get it started, and to my understanding they basically got connected across the 24 volt battery array with a very large switch..

And the unit I have to fix just uses two 1 Kw 28 volt switched mode power supplies running at the max to power the light and two large fans to cool it..

Might give it a go when I can safely enclose and cool the lamp. I have heard of using a welder as a power supply but the smoothing needs to be improved for stable lamp operation, but batteries would be an option.
