What do you use if you have halides? I'm running 250w 20k. It's time to change bulbs so I'm seeing what opinions are out there

I ran AB 10Ks for years (althought they're supposedly more like 13-14K), but they're butt expensive. I've had Pheonix 14ks on an old frag tank, and am switching over to them at my next bulb change (which will be soon).
I've ran both the XM 15K and Phoenix 14K and liked them both. I've got an old (used around 7 months) XM 15K DE you can try out if you'd like before you purchase, you could also look at my tank that is running the Phoenix 14K right now.
Are you kidding me? is that really what they cost per bulb?
What I'm using... Only 150 WPhoenix are a good option at 14k.
What I'm using... Only 150 W
I personally would have to run some blue T5's with 14k MH to get it to the color I like.
