XM 20k bulbs, anybody have pictures?

[weap0n_X]

I am thinking of upgrading my bulbs to 20k XM's. Anybody have any pictures of their tanks, corals, etc?

i dont have pics but i can explain in short version. they are deep blue, and its hard to se alot of rock structure and some corals. i went from a 10K to 20K and then to a 14K, and stayed with the 14K. have Happy New Year!

i would only recommend xm 20k if you are running 400w magnetics.

400 watt 20ks

ive run xm20k and xm10 250w with pc actinic and i found the colors are better under 20k but growth was minimal and the tank was not bright at all, a very subdued lighting like you are deep in the ocean. i like the 10k much more with actinic supplementation. everything is much brighter and i find that i can get colors that are almost as good if not better when all my parms are in check

id say run em 250w or 400w SE bulbs off HQI ballasts. the helios look awesome.

I have an XM 20K at 250 watts ... and it's color is nice but if you plan on growing SPS it's painfully slow apparantly.

very nice indeed...

i currently have a 400w 20k xm and a 10k reeflux. i am going to replace the 20k with another 10k. they are too blue and i have noticed the colors tend to lighten up a bit over time. my orange caop turned pink! i was not impressed! i say if you want blue go with a 14k. stay away from the 20k. IMO.

The XM 20K 250W and 400W are totally different looking. In my book the 250W bulbs are very blue. I run the 400W on a mag ballast and the color is perfect whitish blue in my book. The PAR is like 128PPFD so the growth is good too.

They also have a good sized purple spike too I don't run actinics with them.

depends on ballast how blue it turns out, but it's a good bulb.
