Really cool! Iād personally sell it since you canāt use it.
Now in order to use that, you have to find a theater projector reflectorā¦. I remember when I was small, my family used to own a small cinema with carbon-arc projectors with very wide glass reflectors to view 35mm film movies into wide screen.
Are the ballast/electronics of these projectors still usable/compatible in your new find?
It seems very difficult to find a xenon ballast that does 2500W on google.
As for the reflector, any electroformed rhodium reflector from phoenix or optiforms can work.
Glass reflectors are more expensive and rare, not to mention delicate.
Nice find. Iād say best sell it if you cannot use it.
Without looking into it - I guess flip it.
BUTā¦. since I know youāre a man of ādo it for the sake of breaking recordsā, I say keep it.
Sorry Iām no help. Good luck either way 
Haha thanks
Would make a nice home decorationā¦a very dangerous one too!
800 bucks will get you a theatrically huge TV. 
Yeah, but not much throw compared to a $7 SK68 !
I had plenty of degraded Christie HD20KJ Xenon bulb (3000 watt) complete with the reflector cage. The price was USD600/piece. The most interesting part were the sliced sphere (parabolic I believe) quartz reflector. If youāre interested I can try to get some from my former company. It creates a tight spot before entering the: UV pass mirror - integrator rock (the round beam transformed to square) - DLP engine.
Setting the correct focus/tightest spot requires dangerous and tedious calibration on a specialized jig.
Will post some pictures later tonight

Agree, if there is one current BLF member who is willing to make a flashlight out of that lamp it would be you , a bit heavy one that is, a quick search gave a ballast of 30kg.
edit: ^ yes nice, pics of heavy duty lighting stuff!
Is that two reflectors??
I think I remember seeing a few years ago pictures of some projector lamp and reflector setups in an osram datasheet.
The back reflector is ellipsoidal to concentrate the light from the lamp into a spot somewhere in front of the lamp (like the UV mirror you mentioned) and the front reflector is spherical, to recycle the light that the back reflector doesnāt capture, just like a wavien collar.
Now Iām trying to find these spherical reflectors for sale to use them as super large wavien collars!
Correct, a huge wavien collar + reflector in one piece! There were 20+ pcs of them. Each bulb last for only 400 hours (already 50% as bright as the new one). Christie rate it for 750 hours. Thereās no way we would use up to 750 hours, itās too dim already.
If you want it I can try to get some. You only need to pay the shipping and handling cost.

Wow, this is really weird, looking up pics of the Christie HD20KJ made me remember these pictures of projector lamp replacements many years agoā¦
And the front reflector is sphericalā¦literally exactly like a wavien collar.
How did I not realize this earlier! These are just wavien collars but with a different name 
Is it a single piece of glass?
All the pictures I can find make it seem like two separate ones, I donāt know how it would be possible to manufacture it as a whole piece.
If the spherical part can be separated from the ellipsoidal part, I will definitely pay for the shipping costs
Thanks for the offer!
And Wavien said itās patented by their name huh? 
Sorry, itās two piece. Itās been 4 years and I hate the job. Below is the bulb removed from the cage module
4000 watt input power, 3000 watt high pressure Xenon bulb, 20.000 center lumens, 16.000 average lumens.
After the first one exploded, everybody left me installing the bulb alone. The picture taken by a friend from my office window.
When exploded, most of the shrapnel turned to powdery glitters due to extremely high pressure.

Impressive equipment. 16.000 lumen is not far from what leds can do nowadays but I guess that the short arc emitting volume is much smaller than a high power led.
Meh the explosion couldnāt have been much of an event, your wearing shorts and sandals? Or is this all you had to change into after the explosion?
A very nice find indeed! And yes, itās very dangerous to handle these without proper protective clothing! Not all HID bulbs are under pressure when not in operation, but Xenon short-arcs are.
The power supplies are so heavy because Xenon short-arc bulbs are operated at very low voltages. The thus very high currents (hundreds of amps) leads to large component sizes and thus wheight.
I donāt think that itās possible to use this in a portable, self-contained light. It also wouldnāt be cost effektive to design a light using this. Skybeamers with these kinds of wattages can be had for around 2K-5k$ from China.
I think you would be best advised to sell it. For 800$ you could easily find a Maxabeam! 
The term āwaiven collarā should be purged from the collective vocabulary, or at least not used out of context. All a āwaiven collarā is is a SPHERICAL REFLECTOR, or SPHERICAL MIRROR, which has been studied since at least the time of Ptolemy, 2nd century AD, if not before. Their patent applied to putting one over an LED, which has a specific effect. A spherical reflector is easy to make with conventional machinery using a ball endmill, and of course can also be purchased from an optics manufacturer.
ā-Later in the day Edit:
Uh, where to beginā¦ my above post, firstly, is a non sequitur. Also, the use of the term waiven collar in this thread was in consideration of the effect rather than the geometry, which apparently went over my head. Thirdly, I too agree that the effect of the device is not novel, from since a few years ago when MEM talked about the effect of the device and how its not novel, yet by mentioning their patent as being related to the effect I give credence to itā¦. And fourthly, a waiven collar, and also it seems the spherical portion of the projector reflector in this thread, is not just some home made optic, or even an electroformed spherical reflector, but a very precise spherical reflector made from glass. Catharsis! Ahh, the forums are good for me, haha.
