Anyone run xm 10k?

[sphelps]

I also use to run a single 400W SE XM 10K with T5 supplement. As stated it is pretty white to start with but over time (IME a couple months) it gets pretty yellow.

I'm into the bluer look now and I keep most of the same corals without a problem. I'd be curious to see a par comparison between bulbs at certain water depths since blue light doesn't get filtered out by water as much.
