Where to get custom ceramic glass for halogen light fixture made in Europe?

So, I have three R7s halogen light fixtures in the living room with 300W halogen bulbs inside. Unfortunately, one of the protective glass broke and since the light fixture is so old (20+ years) it's impossible to find a replacement.
I looked around for websites that produce custom cut glass and found a couple: One Day Glass and Glasstops UK. The first site does not ship to Europe and the second one has a minimum size of 250 mm x 250 mm for ceramic glass, which is bigger than what I need.
Is there a website that can cut a racetrack oval shape of ceramic glass of around 13 cm x 6 cm and drill holes in it, and also ship to Europe?

I could also replace those fixtures with LED ones, but I haven't found any LED indoors fixture that looks good and has an output of ~5000 lumens (and is also dimmable). If anyone has any suggestion please feel free to share them as I would love to switch to LED.

Here are some pictures of the fixture:

One option could be to get square piece and find someone local to water-jet cut it. The problem is, someone need to do the cad for at least the oval and probably the holes. You can try with a ceramic bit, but probably better off to water cut. I don't want to even think what a one-off will cost though.

I contacted One Day Glass and they said it would cost $65 for the glass piece and $89 for shipping to Switzerland, which is a bit too much. I have yet to find a ~5000 lumen dimmable LED wall fixture that looks decent though...

Not from the usual outlets but possibly from an architectural lighting supplier. I would not expect anything cost effective and it will be larger. What are the dimensions of those units? They look like they have beefy heat sinking ... but I would have my doubts if they have enough for 50W of LED (or so). You would need to remote the LED driver as well and that does not look possible with the mount. A bridgelux COB could give you the lumens, probably even the color quality, but not the warm dimming if that is important?

The units are about 190mm x 85mm x 80mm (L x W x H). I don't really care about the color temperature control, if that's what you meant, as 2700K-3000K would be good for the living room.
I looked around various brands (and still am) and the closest thing I found is the iGuzzini iPro 192mm. I have no idea about the price, but they're good for 5300 lumens and are dimmable. They are quite heavy at 6kg each and are not sold in black, which are my main problems with it.
I guess high output LED indoor fixtures are not yet feasible, probably because of the need for lots of heatsink material. I might start looking for metal halide fixtures or neon lamps...

Completely feasible, but normally they would be used for uplighting ceilings in large indoor installations, not residential.

NEON is a non starter. MH does not dim well.

I mean by CCT in that a 3000K LED will be 3000K through all its dimming range.

There is probably enough heatsinking those for a fairly large LED load .... but not sure where the driver could go. Enough space, but you need the LED to couple well to the enclosure and preferably not cook the driver too much.

You are looking for an Indirect Wall Mount light : http://www.cooperindustries.com/con...g_wall_mount_lighting/wall_mount/_868326.html

They are very common in commercial installations and you can expect many times more expensive than your halogen fixtures. You may also find things under wall mount uplighter.

Careful as some that point up are wall washers with narrow beams. You just need a flood.

I don't think I have the knowledge to Frankenstein the fixtures with LEDs plus the required drivers without setting something on fire :sigh:, plus one of them would still be missing its glass protector which would collect dust on the LEDs (I'm assuming that wouldn't be a good thing for temperatures and reliability).

On a side note: I tried using my DSLR's exposure indicator in M mode to compare the R7s reflector with a 1500 lumen floodlight and a 1300 lumen flashlight, and they were very close (300ms shutter speed, f/4.5, ISO 800). Now, I'm no photographer, but I'm assuming that if the exposure indicator shows the same value, the scene is lit with the same amount of light, which brings me to the question - could it be possible that a ~2800 lumen LED fixture would produce the same usable light as my current halogen one? I know that with a reflector some light has to be lost, but I didn't think it was that much. I wish I could try out one of these and see for myself...

I wanted to see if it was feasible to retrofit LEDs in the halogen fixture and am having some issues in choosing the right components, maybe you could help?
I found a low profile LED driver (with TRIAC dimming) which I could fit in the fixture with some minor cutting, it's the ERP ESS040W-0900-42. Next step would be finding an LED that won't consume more than 37.8W, which is the driver's limit. I found the Cree CXB-1830 which I think would work but I'd like to be sure: the datasheet states 36V and 800mA (and a maximum of 1.4A). I'm assuming that running it at 900mA would maybe only shorten its lifespan a bit, is this correct? This would put it at (36V * 0.9A) = 32.4W which is less than the maximum power of the driver.
Would this work? Do you think there are better components around for what I'm trying to do?

I needed a round piece of glass to cover a very hot bulb. I went down to the glazers and he had a scrap of Pyrex glass from the window on a wood stove. He had no trouble cutting out a circular piece.
