    PPFD is a measurement of PPF for an area. So you just take multiple measurements and average the numbers to get the PPFD of a given area. Since the meter measures a single point you can get this info from the standard output.

    I am in a way. I'm making the prototype now. We will see though. I'm getting messages daily about it but I don't expect the first campaign to hit record numbers, most people want to buy after they see a working model which is fair. Especially after talking about the 600W for $600 option.

    Its the staggering I'm referring to. The color is interesting and may help. Wouldnt mind testing it out more.

    To be fair I'm using house and garden(A&B) for coco, Mammoth P, Botanicare Calmag +, and TM-7 in 30 gal fabric pots. Zero deficiencies and I can skip a week of feeding without issues. I'm under 4000K and 2700K same across the board.

    Unrelated to that, Love the dog photo.

    Slight update. I'm waiting to hear back from a company that gives a better rate at lower quantities. If they will ship to me then Ill be able to drop the required funds from 300K to 100k and drop the lights cost by 100USD per item. Since there has been a bit of buzz around just buying the boards...

    Might be because it takes more time to layout the board with them in that fashion than a straight line with a minimal space savings. However I do like how they mount their boards on angled aluminum which gives me an idea. Its also much cheaper to use the LM561C since they are an older component.

    Fair, however these were all the same plant via cloning. I've grown all the way through veg and flower with 2700, 3500,4000 and what ever spectrum the 315s are. I'll be able to test more when my room is all one style of light and I can move my 4000k to be only veg to show the dramatic...

    Also if you scroll to the right there is a donation button if you want to toss in a dollar that's also appreciated!

    Thanks! The way I see it that's less than 500 600W lights with some donations to win one. The boards are waiting on parts that are on backorder. I'll be posting more once I have the boards running. No I didn't consider using a bus but I may experiment with it. The 600W driver has two sets of...

    Share the crowd funding around anywhere you think someone might be interested! That's support enough for me. As I said I'm making my room use these light exclusively. Makes summer growing smooth sailing not needing AC

    That's correct it can only be wired in series. The 100W boards will run at 44V (the HLG-600H-42). Again the SL can not be bought for the 3000k anywhere. Samsung's spec sheet says they are there.. but their representative said they are not. Making SK the only viable option. Dimensions per board...

    It's in there somewhere, but I'll post them again. The boards are planned to go to 200W with a heatsink and 100W without one. Color accuracy is important to me which is why I chose a more accurate diode than what HLG uses. Instead of using the whole binned option I'm using the Macadam 3-step...

    I was able to pull them from other companies that use them to cross reference the data. Samsung was also very helpful.

    Yes I did take that into consideration. Yes its all currently off of real world calculations that have already been taken for the LM301B SK 3000K. Thats how I know they are accurate. Ive been around on the LED side for a good bit of time as many people around here know.
