reflector
If the reflector was mounted ina manner that it could be adjusted... the way the club lights work is the reflector is mounted solid, then the bulb (MSR-400 / MSR-700) is adjusted.
There are studio lights that use these bulbs (HMI 1200W/GS) and ballasts that go with them.... Not sure what the prices are like. I tried to go after a setup to runa MSR-1200, but missed it.

Okay, the 'huge fresnel for smaller arc' idea has been scrapped, and I'm abandoning long-arc 1kw bulbs.
After spending 3 hours figuring out a good layout, and then re-trying it with dual lightsources to represent the non-point sourcitude, I'm gonna scrap this idea - negative fresnels to collimate the light kill the effect, and I think you could probably get the same number of lumens for the same lumen/arclength ratio, which is relatively constant for 400w->1kw.
To clarify: The arc length is about proportional to the wattage and lumens, in most reasonable life bulbs. The 400w bulbs lumenlabs use have an arc length of around 25mm, the ones I was looking at were around 70-80mm for 1000w. The problem is that no matter how I toyed with a fresnel, the arc length seems to be about inversely proportional to how much light is usable at the triplet. Playing with fresnels just allowed me to accelerate the rejection of off-axis light that distance alone could get me, but which also hurts lumen output even more.
New priority is a low arc length 400w(One of the high CRI HQIs probably) or a <750w low arc length / long life bulb if I can find it.

There are literally tons of shorter arc length lamps.
Single ended, MSR-700 and MSR-1200. The life on them is about 1000 hours though.
The bulb I'm looking at is the HMI 1200W/GS. Arc length is something like 24mm, 110,000 lumens. Going to need a cold mirror though, that is going to be a pain.
The really difficult part is finding a ballast. Early on I was hoping I Could use one of those cheap 2000 watt long arc bulbs, but everyone said it wouldn't work so I abandoned the idea.
I sent an email off to get a quote on this ballast:
http://www.warnerpower.com/pdf/HMIMSR1200_1.pdf
It is for driving the 1200 watt HMI and MSR bulbs. My goal is to be able to drive up to 16' wide image (outdoors or rear projection indoors at trade shows and such). I have bad feelings about cooling the LCD though.

I need something with a long life. I intend to use this as my main computer monitor, many hours a day.
Find me something with an arc length <15mm that's in the range of >400w and <1000w, has decent color temp(4k-6.5k) and costs less than 2 cents/hour in bulb replacement costs, and you get a cookie 🙂

I don't think you will find anything with those specs :-(
Is there really problems with arc lengths over 15mm?
Like 24mm? 🙂

Not at all, but generally, arc length and wattage are roughly proportional. Or rather, wattage * ratedlife is proportional to arc length, usually.
Although OSRAM xenon XBO lamps would probably be ideal (They're the premier movie theater bulbs), they're too short-lived.
I'm looking at the OSRAM Powerstar HQI bulbs now, and I like what I see, but their spec sheets + availability for this particular product are terrible(and they're one of the better companies in this regard).
They have 1000 watt bulbs with a 31mm arc length with excellent CRI, color temperature, and lumen output, that I have a hunch are decently long-life, but can't find the rated hours or anywhere to buy them - they're supposedly used as stadium/architechtural(sp?) directional lighting. This may mean that their only avenue for selling these is an agent that does bulk orders 🙁
Their US agent, OSRAM Sylvania (Oddly, I can't tell if they're a rebrander or a rebrander+competitor), may or may not carry their upper end HQI series, I havn't been able to find out yet.
Keep in mind with your lamp that it's most likely at dangerously high pressure - don't drop it, or you'll need exploratory surgery to remove the quartz shards.

Nice lamp choice... interesting!!
I saw this brochure before but I believe I thought the arc length was too long.

Powerstar HQI-TS 1000W / NDL/S

I can't seem to find hours, or US prices. The UK prices seem to be cheap. I mean, if the bulb only costs $150 USD and lasts a long number of hours.... It might be perfect for my 12'-16' wide projector project.

SCORE!!
Thought it was a long shot, but I browsed through their on line catalog, and found an unlabelled link to a series of images. Half the links to images were themselves unlabelled, so I just opened all of them.
Here's what I found:

http://catalog.myosram.com/sap/its/...4050300300108&strFormat=&strResolution=midres
7500 hours is within the acceptable range for my usage.
Now we just need to track down a supplier.

Nice! Watch out, the 2000 watt versions have a much lower color temperature.
Will this run on a standard industrial 1000 watt ballast?

Uh oh:

Eye Lighting had some lamps that were perfect, although ballast was expensive. Short arc, and 2500 watts. Not availible in US, Japan only.
Something about still needing to get a fixture approved.

They have the transformers, capacitors, igniters, and frames available seperately on the osram sylvania catalog site, but no extended info on any of them, nor places to buy them.
Osram Sylvania: Business lighting section has an email inquiry pending re availability, response should be 1-2 days. My record with actually getting manufacturer responses on product information is about 50/50, but I presume that they should be responsive since I'm asking where I can buy their products.

Awesome. I got a reply this morning from warnerpower.com, who makes ballasts to drive 1200 watt HMI and MSR lamps.
Sticker shock, I must say:
-------------------------------------+
Ethan,
Thank for you for your interest in Warner Power. The ballast you are looking for
is our part number 70-004710. This ballast requires a separate ignitor, part
number 50-002900. Lead time and pricing are below:
70-004710 $1,959 6 weeks ARO
50-002900 $226 6 weeks ARO
Please contact Kathy Bolduc at the email above if you would like to place an order.

I found the HQI-T on their website, but I'm not sure if this is the long arc version or what.
The prices... I'm not sure if they're for the case or for the bulb. I'll have to call.
The HQI-1000-T (not TS) is "Unit(1) price: $723." In that column it says "Case qty 1," "Mast qty 6," "Pkg qty 0."
The HQI-2000-TS is "Unit(1) price: $979," "Case qty 1," "Mast qty 10," "Pkg qty 0."
Is there any chance you actually go through with $2k on a ballast? All rationality tells me someone wouldn't, but then again, you wanted to pay $300 for a 750 hour bulb 🙂

No way, could never drop that kind of $$ for a ballast. I could get a used club light from eBay and pull the ballast out of there. Evidentially a MSR-1200 ballast will run the HQI-1200.
I like the idea of $100 ballast, $300 bulb for 750 hours, 16' wide display 🙂 But I'm not sure if it's realistic.
MSR-1200 + ballast might be the most economical solution, as MSR-1200 bulbs can be had for $100 and do 1200 watts @ 750 hours.

According to an argentinean spec sheet, the HQI-T has a 50mm arc gap.
On a british vendor's catalog, the HQI-TS 1000 D/L is $743 🙁 And no mention of quantity.

~US$383, in slovenian dollars - only $409 for the 2kw one
I also found an "HQI 1000w" lamp made by 'Ventury,' on a brasilian site for $73: http://www.lampex.com.br/OUTRA/page/vapor_metalico.htm
Bears investigation.
Also, on a UK site:
http://www.aalighting.co.uk/product_info.php?products_id=1766
83 pounds.
WTF is with the pricerange on these things?
Maybe they sell unbranded versions at a tenth the price, or I'm actually looking at prices for a package of them?
I'm pretty sure HQI-TS 1000 d/l is only associated with osram bulbs, but still...

And we may want to think about making at least the bottom, base-plating for these things out of steel rather than aluminum: http://www.popsci.com/popsci/how2/article/0,20967,693558,00.html

It took a while, but I've finally nailed down ballast+igniter for the HQI-TS 1000w/d/s:
With this much spent, I'd probably be hurting myself if I didn't find a decent elliptical reflector, which should dramatically increase light output.
As well as either a 240v circuit or a 120v-240v convertor of suitable wattage, which should run me I think $80, and the 50uf high-voltage(need to find out how high) capacitor.
