Ushio 250W 14K...
 

Anyone used the Ushio 250W 14K bulbs in there reefing life time?

I am trying to figure out which bulbs to use on my 75G. I will be supplementing with Super Actinic and Fiji Purple T5's. I was originally planning on a 20K light, but not sure I will get the same coral growth as a lower K bulb.

Anyone got pics of these bulbs on a similar size tank? Or reviews? Or a better option? I'm avoiding 10K, usually far to white for my liking..

Hmm was just reading on RC that these bulbs are only intended for PROPER use on an M80 ballast... e-ballasts supposedly don't run them to the full potential. :neutral:

i have a ushio 175W 14K and i find its not blue enough for me but is very bright and looks good but needs suplmental atcintic
