Very nice work, Indy!
I hope your creation hits the market soon, there are many people who want CXBs as their new light source but cannot build for themselves, so a panel like yours comes at the right time.
So I see you're more for higher intensiry, I also like that. It's a good platform for shifting on from hps where intensity is high.
I read a lot the threads about such DIY projects and must say the numbers are always impressive, no matter the current you always get great efficency with this configuration.
I also like the "soft" route with more cobs at lower watts for a more even light distribution, but it has higher initial cost, probably not so good for selling them after.
You know what I suggest?
Talk to the AFN owners and mods, pick a couple testers and make your own forum section here, it should help you reach potentially interested people and spread the word quicker. If Mars have their section, you should too.
I fully support this kind of business and if I were from US I'd probably have one of your 100W lights. Would probably build my own too or try to make a similar business as you

Best of luck and please post more pictures along your grows.
Cheers
