I've just got my first set of pheonix bulbs on friday, and the color is amazing! I'm planning to by the same bulbs again, next round.

I am running Ushio 10K right now, and they are far from yellow, actually very very white. When I ran the pheonix, they were 14K, and I can say they were really nice also.

I'm basing my results off of JDigits 75gal when he lived with me. He had to add supplimentals after due to the kelvin of bulb. But to each their own. Personally, the pheonix was amazing after everything I have read. It did get a bit whiter since I plugged it in

I think another good thing about the phoenix is decent quality for a decent price. I bought my 14K for about $70-80 per bulb. Not bad for what you get, compared to some of the more expensive units.

exactly. I think they are only $10 less than the ushio. How much are the GE's going for?

I have SE 250 halides, I have an XM 10k in one, 15k in the other. The 10K is obviously more "yellow" I'd call it white actually... But the corals are amazing under them, my high light corals LOVE the 10k. I wanted to run both for a bit to see what I liked, but I'll definitely be getting another XM 10K.
