Well, I didn't get as many pictures of this process as I would have liked. It didn't turn out as "professional" looking as I would have liked either, but oh well, it surves it's purpose. I purchased the IceCap 4x24 t5 retro kit for my tank w/ intentions of buying another 2x24 so I could keep anything I wanted in the tank.

First I started with some 3/4"x3/4" aluminum angle iron. For my 45g cube it's 24x24 and my usable area was about 24x20. I made the sticks 2 @ 24" and 2 @ 19". Then I took and cut some 3/4" square tubing (also aluminum) and cut it to be 19". The square tubing was used to attach the end caps w/. Here's a pic of the pieces before starting:

Her'es a pic of the first set of pieces put together, it's hard to see it on the table saw, it's the square lookin thing:

Here's where I skipped a few steps in the photo process. Basically I made another square with the 3/4" angle aluminum and then attached the two squares together using more 3/4" aluminum that was 3 1/2" tall. So I have a box type thing now:

Then I stopped taking pictures again until it was done :( I'm so forgetful. But I took aluminum flashing and rivetted it in some places and screwed it together in others. I made the top and one of the short sides w/ one piece, and then both long sides were seperate, and then the other short side I put on last so I could take one side off and do whatever it is I need to do in there. I painted the whole outside w/ krylon fusion and then added a piece of plexi as a splash guard. I also added some 2x1/8 strips (4 altogether) and attached those to some more 3/4" in angle as rails to sit on the tank. Here's the finished product on the tank:

As you can see the thin aluminum flashing leaves some "wrinkling" effect, I'm sure if you used something thicker it wouldn't do that. I was going for as light weight as possible so I don't mind it. And in the next picture you can see the bulbs. I centered the 4 in there so I'd have room to put 2 more on the outsides, but it's hard to see in this picture:

That's all I got. Looks pretty good to me (knowing I'm not a professional in any way with metal), and it's light weight which was the ultimate goal. Thanks for looking!

It looks fine. It gave you lots of experience and ideas on how to do it again, right? :)

Have you thought about adding individual reflectors for your bulbs? It is nearly essential to get the proper benefit from T5's.

I usually consider my first attempt to be a sort of rough draft, or a training mission :)
