Anyone run xm 10k?

[Funky_Fish14]

Brett, I used to run XM's over the old 75. (They were 400W though, but yes SE/Mogul) Had a 10K bulb in a PFO HQI Ballast. That thing runs like a champ, PUMPS the light out like mad, and views as a PERFECT crisp white. No yellow unless on a CRAPPY ballast or very old bulb. Its just white. Initially when I just had the one 10K over a 33g I ran it with a 96W actinic PC and it looked pretty awesome. IMO your selection in the first post is an awesome choice. Until I decided not to go so hardcore with my reef thats what I was going to be running in a lumenarc over my 52.

Hope that helps,

Cheers,

Chris

I'm running a 400 watt 10k mogul lamp(XM) and a 175 watt 20k mogul lamp(XM), have noticed some yellow now that you mentioned it. Also noticed that the coral is not as colorful. it's basic colors like brown, green, and some yellow and that's it. Do other more expensive lamps produce better colors?

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.
