what type of MH bulbs?

[atcguy]

I started with hamilton 10k. that came with my 250w reefstars. Crap bulb. very yellow. Then Geismann 13.5 k. then Xm 10k . all with VHO actinics. I now using Phoenix 14k with my blue vho actinics, and as of right now have never been so happy with my tank lighting. Awesome colors , hint of nice blue. When first fired up they were really blue but after 2 weeks they are perfect. Try them...

I have been running XM 10K's for the last several years and recently changed to the XM 14K and the colours on my SPS have changed significantly. The 14K's are about half as bright as the 10K but the colours in my SPS have taken off. it may be to soon to tell but it may come down to growth vs. colour. My 2 cents!

I second your comment. I went from a 10k XM to a 14k XM and also saw a great deal of color changes. I saw much deeper and brighter colors throughout my system. The downside was that I got a lot of blue and purples.

What kind of color changes did you see?

250W DE 14K Hamiltons, bright white edging on a bit a blue, no yellow. Had a couple of premature failures (I'll chk my logs for life)

re: early failures with Hamiltons, one failed early at 6 months other 7 months, though have removed others still running after a year.

I'm running XM 10K as well but want to try South Pacific Sunlight (SPS). I've heard a lot of good talk about 10K, 14K, and even 20K

I like my 14k Aqua Connects, had 10k Ushio before but seemed to yellow out fairly early. All this based on SE bulbs though.

i just switched to aqua connect 14000K 250W DE from the standard coralife 10000K that was in my fixture, and the colors are much nicer, and it seems just as bright.
