Look at post 774 on the previous page. I ended up not using those rail brackets. These light are sure making a 72" span bow fairly badly as well.
I like that idea a lot!!!! But... I think I found what I need. Package B from maxspect. It is made to span front to back of the tank and the elbows in package E just attach straight to them. completely solves my issues I think. Take a look and let me know what you think.

I'm currently looking to convert my FOWLR 55g long tank to include corals.
Should I go with the Evergrow IT2060 or the IT2080? The IT2080 seems a bit overkill for my tank though. If I do go with the IT2060, should I be using the 120° bulb to spread the light further?
You definitely want the IT2080, if that one is even enough on a four foot tank. I have the 2060 over my 40 breeder (36" long tank) and it's very marginal. I may upgrade to a 2080 very soon.
If you look at the reef koi's. they have a little bracket in the corners for a brace.. Maybe you can either brace it for support or move the support further out on the rack.
after running the light for couple days, finding the default layout to be just a bit to much blue for me. so far running good.
I find that interesting. Most people want it to be on the blue side.
Anyway what setting do you run you d120 on that is too blue? I thinkg the beauty of these lights is being able to customize the channels to your liking.
Is he value fixture on reefbreeders the same as the dt120?
