Im looking to buy a mogul based 250 watt 14K bulb. Any suggestions?

Are you unhappy with your Phoenix bulbs? I'm running XM 20k, but haven't tried anything else. I'm wanting to try Radiums next, but I've got a magnetic pulse start M138 ballast and the Radiums need HQI.

I have to update my tank info. I currently have a coralvue all in one fixture with 250/400w electronic select a ballast. I am running 400w 20k Radiums and they are bleaching some of my acros so I was gonna go to 250w bulbs. I have read that 250w Radiums dont fire up right with coralvue ballasts. I really like the blue look so I want to go with a 14k bulb for color and par.

They have phoenix mogul base bulbs, I have not use them though. The 400w 12k Reeflux bulbs gave me good results but from what I've read the 250w had issues.
I currently run 250w radiums in one of my tanks and it’s the best bulb I ever had, but I guess you can’t use them.
How high is your fixture? the 400w radium is a great bulb. I'd just try to raise the fixture or acclimate the corals by shortening the photoperiod and slowly increasing it.

I moved the fixture from 12" above for 8 hours to 18" for 6 hrs. I only ran it for 6 hours for a week. I tend to be a little impatient. I should have started out that way going from 250w 14K phoenix's to 400 watters. The guy I bought the light from gave me a set of XM 250w 10K bulbs and WOW they are really yellow. I dont know how anybody uses those bulbs. They are in my fixture now, I dont know if I should get a set of 250w 14K's or put the 400w Radiums back in and give them a little more time with 18" from the water for 6 hours. I know 400w Radiums are one of the best bulbs and I really like the blue color.

Reeflux 12k 400w. Do great with that ballast
