Successful DIY Panel Achieved Yet?

This forum is definitely the epicenter for cutting edge LED conversations. Really amazing and generous contributions. Obviously Sns has it going on with his Procyons (with some augmentation LED panels?), so LED clearly works.

I want to build an LED rig for Scrog (6-9 sq. ft) and very much appreciate the work posted here for differential wavelength output LED panel design. Amazing open source research (where oh where has Physics gone?).

Has anyone come up with a semi-definitive recipe for panels that would fit my application size?

I'm not concerned about cost. It's the low heat / minimal venting that I need for my sneaky sneaky room. Plus I absolutely love the technology.

Again, I've read many threads here and elsewhere, but haven't found anyone that has said "I would build more panels just like this one..." All designs seem to be in evaluation stages still.

My thanks to anyone that would be so kind as to point me in the right direction for a step by step how-to.

Thanks
