28LED Build -- Done
The LEDs game last friday, so I spent the evening gluing them onto the fixture and wiring everything up!
DIY Aluminum Fixture:  I used 2 of the left piece side by side for the main body, and I interlocked and riveted in all 4 sides with the right piece. Top View:  Bottom View:  Side View:  LEDs:   I was going to install a piece of plastic on the bottom as a splash guard, but I havent gotten around to getting the plastic. But now I'm wondering if it's even necessary. I'll probably hold out. Grommets for running wires through:  Wired up (48" strip of blue LEDs as Moonlights wrapped around fixture):   Temp electrical station :P  Top view with fans (80mm Aluminum fans with blue LEDs, fitting):  Front View:  Fixture runs COOL TO THE TOUCH on full load. Blues at 800mA, Cool Whites at somewhere over 1000mA. One of my goals was to demystify the belief that you need those honking 20lbs+ Amplifier style heatsinks. Pretty cool that ALL the parts of the fixture are aluminum, from the body to the rivets, and even the 2 fans and the screws are Aluminum. I'm very happy with this LIGHT WEIGHT fixture. I had made the 8LED Fixture, and now this. It's been really good practice. This second one took me no time at all. It's all about the planning. However, I did not anticipate building this 28LED fixture, so the big fixture for my display tank has been pushed back to next year. I just got a new order of bulbs, so they should hold me over until the next LED build (I'm thinking around 60 LEDs next year).

Nice job!! that looks fantastic. People never believe me when I tell them they can use U-Channel for their heatsink.
Keep an eye on the frags at the top of the tank,t hey might bleach with all the new light.

what has been said though and provin is that if you have a fan failure and are not home to catch it or didn't build over temp protection into your design then that cheeper lighter heat sink puts your whole system at much more risk than a higher watt/in2 heat sink would. got any pics of it with everything on full?
