Bought a 10K AB SE 250W Bulb. Any experiences?

[dirtyreefer]

I just ordered this bulb from the states, but am wondering if any of you have tried this bulb before? I would like a nice crisp white output, and have heard some people say that this is the bulb to go with. I have also heard good things with XM 10K, but I got a really good deal on the AB.

I have seen the post on RC which "Joe" does a comparison of the 250W bulbs, but he doesn't have the AB 10K bulb listed.

Anybody own these bulbs?
