I have the IM 20, essentially the same tank only 24" though. 2 bulbs would really limit me in terms of coral choice and spectrum. If you want SPS you'll need those extras.
That said, I run 2 blue+ from 10-10 and the other 2 bulbs, coral+ and blue+ for about 4 hours in the middle of the...
Thats what I have, just the 24".
Nice light. Do replace the bulbs as I stated above.
Has fans, two I believe for the 36". They are not the quietest fans, but not at all offensive either. You will be able to grow pretty much anything anywhere with the 4 bulb.
I was going to ink that for you...
I wish those Tek units were still around. Well build lights and right up there with the ATI sunpower for output
I'm always searching for a 24" unit. One day I'll find one
That link is the Coralie you posted eariler. Only 30"

In theory yes. But i
In theory, yes.
But its a tank mounted light so if you have a 36" wide tank............

I thought you mentioned 36". That light is 30"
I use a Current extreme 4x24 on my fusion 20. I dont feel it adds any considerable heat at all. At least I dont really feel it on my had under the fixture. A fan pulls air in from the sides and out...
Wrapped, unwrapped, coated, uncoated.........
At some point water gets in.
I've seen it happen in plenty of different frag racks and plenty of other equipmentas well. Vortechs and koralia power heads have a pretty good history as well.
Once that covering has the slightest unseen crack its only...
