They look like Osram HTI300 lamps to me. Very nice colour rendition, and if you don't keep trying to restart them when hot, and run them for at least half an hour each time you turn them on, then you should get around 800hrs of useful life.

Make sure the pinch seal on the capsule faces down, or they could explode. You will need UV filtering!

Default lamps

Here a link to a lot of lamps:
http://www.eurotekmarketing.com/lamps/lampsnew.htm

you can see there the HTI 300W/DX


BTW

I found a lamp: OMNILUX ODM 150W G-12 6000h 6000K .
with the same 230v like the CDM-T 150/830 Lamp(same ballast).
About a 9000-11,000 lumen

search in this link for "OMNILUX ODM 150W" (you also have english ver to this site)

The lamp / ballast set was bought from a factory near me, but they
don't do export. the ballast is 220V only. To make it accept 110V
input, the ballast needs to be modified. The manufacturer requires at
least ten sets to be ordered in order to make such change.

18wheeler is going to setup a group buy. You can contact him.

18wheeler ! the screen is 100',

ywh,

Will this lamp work with a 250W electronic ballast or will it only work with the supplied ballast?

I'm asking because I may buy several lamps but if the ballast was to die then I could use a locally available eballast.

I am tied up with the work right now. More pictures and comparison
will be posted once I have spare time ( in a few weeks).

So far, picture with this lamp is brighter than 250W HQI. in the
picture posted above, the sky is almost too bright to stare at. My
eyes hurt when looking at the bright area. I also feel the picture is
sharper and contrast is increased. Comparing to this lamp, HQI seems
to have a 'softener' lens on.

I tested emitted heat by putting my hand in front of the light. It
feels cooler than HQI. Heat glass is no longer a must-have. Also lower
speed fans can be used, so noise can be decreased too.

it might, but I doubt a normal ballast can power it. the tructure of the lamp is very much like a small version HMI 575W. HMI uses very different ballast as far as I know.

It is expected because there is less defused light, which would blur the image.
