Check on the DIY forum here and on RC. There are dozens of threads about LoA lights and also some with specific information on the Fluorex bulbs. Just do a forum search under the DIY sections you'll find lots of specifics.
i have a LOA very similiar to yours for my refug, but also went through a couple... think just got too hot even though said can be used outdoors. I do like the light though
I've kept some montipora frags under this light very close (about 6 ") and gotten growth. It's only been about a month or so in my refugium. I wouldn't plan on this substituting MH unless it's in a very tiny tank.
