I have a 175w probe start PFO ballast. I was using an AB bulb, but recently switched to Ushio before I learned that the Ushio will not fire on a probe start ballast very well. So, I am switching again.

Which bulb brands are best quality? I.E. which have the best light intensity and which last the longest at the proper intensity? BTW, I am looking for 10k bulbs. Ignore color right now though, I am just worried about quality first.

So far ive had my xm10k's for 4 months now, havent had any trouble with them, no complaints. They put out a very high par on my ballast.
