It had "complex" circuitry and as far as I could tell, it first applied

up, would boost the voltage to 600 or so.


I know nothing about gas discharge lights, I was wondering if anyone
here has an info. As far as I could tell, they emit a lot of UV.

Are you sure about all these details?

From your description, I'm thinking this could be a Mercury short-arc lamp.
Check eBay item 201564167114 and see if your bulb looks something like
that.

If so, it takes a high voltage to strike the arc, and then runs something
like 4 A at 60 V or so, for a 200 W lamp.

Mercury short-arc lamps (as opposed to Xenon lamps) have a couple of really
STRONG UV lines that are good for exposing photosensitive materials used in
the screen printing industry. And, WATCH out for your eyes, the UV out of
these things can be BRUTAL! ONE minute exposure will give you a blistering
sunburn.

There are other exposing lights I've seen that had a zig-zag tube like a
tiny neon sign lamp. I've never seen the power supply for those.

It is not one of those, thank you, I will post a photo later.
There is nothing inside that I can see.

At any rate, if this halogen lamp works, it will probably be safer

yeah, we need to know what type of lamp really. Telling us the light colour would be a start, and over how long the brightness increases.

Found a part number , it's this

It seems to be a 5000 watt lamp

HID lamps aren't my thing, but I believe they take a huge voltage spike to start. Halogen will give a small fraction of the output at that wavelength, increasing process times hugely.

He said that it could do a burn in a minute or two but he does not need
to go that fast. He is hoping to do it in less than 15 minutes...so I
will have to wait for him to test it to see if it works at all.


Thank you

Be very careful with that lamp. They are under very high pressure and can
explode if dropped or scratched.

Thanks for the warning, I'm going to wrap it carefully and put it in a
safe place.

Note also numerous warnings about "DO NOT TOUCH"
Finger oils on the bulb can cause catastrophic failures.

That much I knew, I wore clean cotton gloves.

If it doesn't work, I'd check all those alternate part numbers in your link and see if any of those lamps could be matched to a ballast. You might be able to source a stand alone board. Or email companies like Ushio and see if they can help.

OK but I hope the halogen lamp I have in there does the job.
