Koondense - that post was priceless, you're a funny guy! Gave me a great laugh and a smile with my morning coffee

about 600$ in cost, with a 96% efficient dimmable driver putting out around 2,7umol/J, better spread, no hot spots
how much more is yours gonna cost? will it be less then 2000?
send one over to europe and it can play against it...
I'm shooting for a retail price of $799 or lower on the 400W model (which includes S&H in the USA). Not certain yet if I'll hit it, but that's my goal. You'll still have about 400 LEDs on our model though. What are the overall dimensions on your unit? Watts? I think you did a very nice job of designing and building your panel. It's definitely going to have a nice, even spread.
A 96% efficient driver and 2.7 umol/joule (which can only be calculated in an integrating sphere) doesn't mean much though when you're using white LEDs where the majority of the spectrum isn't absorbed by your plants. If it meant anything HLG would be besting us right now in that side by side with their many advantages other than spectrum. So basically you built yourself a HLG light with a more even spread, but it's still a white light at a similar efficiency to the one our older technology is currently besting. I do give you kudos though for building your own at a cheaper price with a more even spread, rather than supporting such a generic company. The problem is most you DIY guys and competitors keep focusing on electrical efficiency rather than photosynthetic and photochemical efficiency. You forget that we're growing plants, not just trying to figure out who can make more photons per watt. How the science of plants has been completely disregarded from the discussion of grow lights is beyond me. Anyone can build a LED light that will grow plants, but only a scientist can create a real LED grow light.
I'll make you a deal Sethimus. I'll get you one of my lights for less than you paid to build yours including shipping to Europe. Run a side by side. If our light doesn't out-yield yours in grams per watt (it will) I'll pay to ship it back and refund your money.
I didn't get where I am today after 10 years by not following through on my promises or living up to our undefeated reputation. No one does the level of R&D that I do to produce a grow light which is how I know I'll win every competition, every time (even with my older tech). So if you want a professionally built light that will outperform anything you can build, for a decent price, take me up on my offer. You have nothing to lose, you can see for yourself the night and day difference between "white light" and RGB white, and you can go from HGL troll to "OK their tech is pretty badass" (even if you still don't like me lol).
