What kind of input from the community, specifically, are you looking for? I did not see any sort of actionable question or request to folks here in your post. Meanwhile, some questions - and a few top-of-my-head musings - for you:

6 'Modules' in a powder coating finish? Sound like everything else on the market made by in Shenzhen by ledstar, cidly, et. al. - with the exception of the SynJet, which is woefully inadequate for active cooling duties if you're going to run 5w chips anywhere close to their rated levels in some sort of 'module' format, without spreading out the emitters into a much lower density. If you're going to do that, might as well just use high quality fans instead.

The best designs will always need passive cooling only - from large heatsinks and well-spaced emitters. Active cooling is merely a bonus after that, not a primary thermal management design priority. Dense modules will always cause entirely too many issues from high junction temperatures (Tj), uneven lighting distribution which mimics old point-source lighting inefficiencies, color shifting, de-rating, and all the rest.

---------------

Q0: What kind of chips are you using, from what manufacturers?

Q1: Are you planning to run the entire module at the same mA using one driver per module? Why?

Q2: Do you have any plans for dimming circuits, either multi-channel or mono-? Will these be 0-10 VDC or PWM? If so, will these be programmable both in periodicity and duration, or manual control only?

Q3: Does your company have a name yet?

Q4: What is your anticipated true wattage draw, flowering coverage area, and estimated list price?

Q5: Why is there no multi-spectrum lighting, only monochromatic emitters? Get rid of the 610nm and add high-bin, neutral white (4000k) emitters instead. The CREE XP-E NW are now available in R3 bins, up to 122 lm/w. The 365's also aren't strictly necessary. Better to put more usable watts elsewhere instead.

Q6: Do you have an estimated release date yet?

That's it for now. Ol' Weeze might stop by and have a few more for you soon, though. :smokin:

Cheers,
