h2oaggie Probably just under $200 for everything with my build.

I am actually selling it now, as I am moving and tore down the tank it was over.

BS87 Both fixtures look very nice! And seemed to be cheap too, total costs <$200?

Geoscouter Cool white appears to be the choice most have gone with. Apparently warm white is too yellow. Neutral is between warm and cool and cool
White has a little more blue. I thought about mixing neutral and cool but they are fairly close in color and I thought it would be simpler to do just one and cool white was closer to 6500k overall. Don't think you could go wrong with either.

winniemagic I'm not sure if this was answered before, but why did you choose the "cool white"? I see that rapid has cool, neutral, and warm.

Geoscouter So I am in the process of building a very similar fixture for my 29 gal tank. I've built the aluminum fixture but have connected the two channels with pivoting arms so that I can set the fixture on the hinged glass top and still open the top to feed. I'm getting the dimmable mean well driver to run the 12 XPG cool whites but unsure what if any optics I should get. With my 3 inch substrate the LEDs will be 17-18 inches above it when sitting on top.

I would appreciate help in determining what degree optic would be best and why.

hamato Well it took me awhile to get around to it but here is my version of this LED build. Same 2"x1" channel aluminum with xp-g & 40 deg optics over a 20L.
Driver is a Meanwell, controlled by a Hydra. I'm still deciding on scaping/inhabitants while the tank cycles.

scapegoat thanks for bumping this! I'm happy to see links to whats being used.

Pen3 I am about to set up my diy setup also, but on a 18" cube. I think i will try 8 XP-G on 700ma meanwell. I ordered 2 green XP-E to test out since i kind of like the ADA-NAG light i had before on my old HQI setup. As for optics i am not sure what to use yet since my heatsink is 9x6.

An aluminum star with the rapidled 40deg optic mounted on it are together just shy of 0.5" tall.

Abrium this was very pleasant and informative to read.

h2oaggie Pictures as promised, sorry for the delay. If there is any particular part of the fixture someone would like to see a closeup of just let me know.

What is the depth of the channel aluminum you used 2"x1"? I want to be sure the optics aren't visible below at eye level as you have done and the optics on rapidled don't have very detailed specs.
Yes, 2" wide with 1" legs, 1/8" thick.

Also how did you end up attaching the LEDs, thermal adhesive?
Correct, just thermal adhesive.

hamato I like the simplicity of this build, and I am planning something quite similar.

reybie I just caught up with the rest of the posts. Finished product looks really good. I like how your LEDs are mounted, the optics are not sticking out.

I bought a DIY LED fixture from a local member that moved out of state. It was designed for a 29 gal also (30" long I believe). I'm going to test hang it and see if it will cover the footprint of my 90P.

I'd like to see the higher quality pics
