I thought I'd share my new Edge that is currently cycling with some plants. I was completely underwhelmed with the stock LED lighting, so I read every page of this thread and decided to build a DIY lightbar with "superbrighleds" using an idea that another member had for the fixture. I went to home depot and bought an aluminum L channel.
Great light mod. I've been working on doing a similar thing. Does the JB weld sufficiently hold the mitered aluminum angles together though?
I'm also curious, why did you use both the angle and square sections? Could you not have mounted the LED's directly onto the angles? Or used C channels even? That's what I'm using and I've painted them already but haven't mounted the chips and wires.
