hmm.. I have a 175 watt 10K xm and I am not impressed, the light is visibly yellow, not much, but it is there, not at all what I expected from a bulb reported to be white with a hint of blue. Maybe it's my ballast... don't know... not to worried as I am planning on switching it all out in the future for 400's.

I think Tim was trying to fire a DE with a mogul type ballast. The new icecap electronic Ballasts are supposed to fire DE. The Unit I bought has a HQI ballast with it. I may change that out down the line with an electronic ballast.

No Tim was using the IC Electronic Ballast DE , I bought his XM Bulbs from him, never fired on my IC but did fine on my magnetic ballast. He tried numerous ballast before selling me these bulbs. He bought a new IC still no fire. The Xm's have a nice color tone to them more blue than the yellow looking Giessmann's I have.
I was going to try the XM bulb on my Geissmann Electronic ballast, see if they fire on them. Will see...
