I got my new lamp. It is for commercial projection use. people use it to replace the bulb in the commercial projector's lamp (the "light" part, the refelctor is kept).

Here is some specs:

wattage: 250W
arc length < 4mm
color temp: 6500K
life span: > 2500hr (replacing, not failure time)
ballast: integrated electronic ballast

I am going to replace my OSRAM HQI 5000K. I will post result in a few
days and compare to the HQI.

I paid about $120 for the whole set. It is cheaper
than a HQI setup.
The ballast is 220V, but the manufacturer told me they can make it 110V if I special order a bunch. It weights about 500g, not as heavy as core and coil type ballasts.

I want one too!!

how many sets is the minimum order to have the manufacturer re-model the ballast to accept 110V? I am seriously considering a group buy for this 250W lamp / ballast. anyone else care to join? YWH, I will send you an email about this.

how about your NEC XGA LCD? have you solved FFC problem? it would be a killer setup to use this 250W lamp + ellipsoidal reflector + 6.3" XGA LCD.

That bulb is a double ended one. It can not be put in an ellipsoidal reflector.

Do you know how many lumens it sends out?

As for the LCD, I'm also interested.
