Looking for a bulb to test with

[colin779]

I was wondering if anyone happens to have an old 175w XM20k bulb lying around as a spare? I am trying to decide if i want to stick with the XM10k's or switch to the 20's. Or if you are currently running a tank with them and are near by could i have a look?

Nevermind, just ordered the xm 20k's, hopefully i like them =)
