Nice! Well it's all about area under the curve, so it looks like there's still a bit more red in those High Lights

Those tcp nums are colortemp (top one is HL). Pretty fuggin close dude!!!
Stick 3-6 fr diodes/pair of bds in the grow for initiator effect, and run em lightson plus 5 to 15 mins, and you leapfrog hlg completly!
I’ll take comparative pic of HL vs HL + extra fr.
Add fr to v2, for lightson part, maybe?

Very Cool Stuff Prawn!. Been interested in the UVA based diodes since i first heard of them. Always felt the closer we can get to the full 380-740, the better.
Staying tuned, goodluck!

But the real question is, Can they beat an HGL panel? Haha! Bustin Chops, sortve.
These basically eliminate the need fir any mono supplements. Interested to see eff levels? Can't be that low if they're beating out QB'S in ppfd. Bigger board i know but still .

We will soon see combined genio-spectrometer results. Maybe next week already. More accurate as sphere tests alone. Its the most accurate testing method for LED lights currently.

I only have Monday or Thursday free at the moment so hopefully it will happen on Monday, if something comes up and I can't do it then it maybe delayed until next weekend when I am definitely free. Do not expect this to be ultra high in efficacy as it does have spectrums that fill in the gaps and that always comes at a cost in overall efficiency, Prawn has done a very good job at the first attempt at building his own boards, he did not cheap out on anything and that's a good sign for the future. Good shit costs and that's something that people miss understand at times.

Yes, I'm not sure if I mentioned this already, but the Nichia Optisolis and Seoul Semiconductor Sunlike LEDs cost about twice as much as Samsung's CRI80 LM301B LEDs used on most other boards. The Nichia NF2W757GT-V3F1 LEDs that make up 2/3 of the board are about the same as the LM301Bs in terms of cost and efficiency, and we have secured the highest Flux bins available for each type of LED (and paid a premium for the privilege). The PCBs are a large diameter and 2mm thick, so are very sturdy. The copper tracks, traces and connectors are built to handle twice the maximum rated current for each board.
The boards were assembled in Australia to ensure quality control as well as ensure the LEDs we paid for went on the boards (and weren't swapped out by some unscrupulous factory in China).
We did not cheap out on anything mainly because we built these boards for ourselves. We sat around one day and listed all the things we would like to see in a LED flowering board and this is what we came up with. Then we looked at a matching heatsink that could do the job for a good price so we could offset the cost of the boards, as heatsinks tend to be quite expensive.
Finally, by putting everything on one board/channel, we also realised we could save money on drivers - plus the board was designed to use common 48V and 54V drivers that most of us already had, so we didn't have to upgrade.
It's swings and roundabouts - pay more for the boards, pay less for the heatsinks and drivers. But matching boards and heatsinks still work out around A$1 per watt, which we're happy with. And the spectrum is pretty much what we were aiming for. They may not be at the top of the efficiency tree, but they're not far behind. Preliminary testing shows them beating equivalent HLG QB324 V1 boards using combined CRI80/90 LEDs.
I guess it's like anything: if we were a business venture and producing hundreds of these boards at a time, costs would come down. But for a one-off like this, there are a lot of non-recurring costs that can't be recouped with just one production run for a few keen growers.
Having said that, we've got the boards we wanted and everyone who's seen them has been happy with the results.

We’ll soon know...when you get your new lights built...and get a new supply of party cups.,,,

Nah, brother! I've still enough cups for the next few years, lol!.
Don't use them usually, they were only used for the comp to show how it goes..
Next round I'm finally using my new wilma system set up as cocoDTW. Want to push yields to the limit to maybe get away doing only 2 runs per year. No fun to grow in your own apartment ... Like Al Pacino says, "I get pa pa paranoia, you know!?"
I'm not the cool sock as earlier and really need the break to calm down.., lol!

Can’t wait to see that new beamer you’re workin on....it’ll have more wavelengths than a mass spectrometer..

Here’s something to tide y’all over until we get the fancy-schmancy, super-duper, cad-cam mapping from @TEKNIK ...
Layout (door opens at side closest to you):
PPFD Maps, using Apogee mq-500, shown in ppfd divided by 1000, for ease of presentation. Wattage is per pair.
Kickass!
Better order soon...

Haha! You're right - I should give him a job as our chief marketer. He can get paid in boards!
