perhaps too abstract,
No we are talking very simple concepts of electricity. Something you fail to understand. You tried to be a sneaky marketeer using a term cool sounding bullshit phrase like "load balancing resistors" and got caught. Now you are trying to weasel out using baffling bullshit. That will not work with someone that understand how it works. Calling it abstract is just adding more bullshit.

Actually it may be worse than that. If you are using resistors to balance the load you are just wasting electricity and it is costing you customers.

It's not a view or opinion, it is the physical realities of electricity stated in the form of fact regardless of your bullshit.
Not sure about what terminology you need, the board uses a combination of series resistors and ballast resistors on the parallel branches, yep a current reg on each parallel string would be better but as I said we are trying to make a solution at a reasonable cost

I'm curious Mark. What kind of driver/s would you pair with these boards. I'm wanting one for my seed to veg chamber. But would prefer to use the board that's got 5000k, 3000-3500k and the Far reds. This is just in case I need to designate it to another task or chamber.

Ok so correct me if im wrong Mark. if i want to drive 2 channels of lm561c @ 1400ma in paralell on the sol-skin a meanwell HLG-150H-54B or ELG-150H-54B would work?
or a ELG-75-C1400B for one channel @1400ma

For 2 channels in series @1050ma the HLG-120H-C1050B would work?
and singel channel @1050ma the HLG-60H-54B?

Ok so i got the Samungs one figured out i hope. what about the Cree's? When I look at the site and see 54 leds and at 669ma for channel 3 and when i calculate 350 (ma for each led) x 54 ( numbers of leds) i get 1890ma so why run them at 669 ma?

So for one board a meanwell HLG-40H-48B you would get 840ma for the red channel and for 2 boards a HLG-80H-48B would give me 850ma for the red channels? Is that ok or do i need more juice?

What would you recommend?

Hi HenrikB,

since you unfortunately misunderstood something..

If you connect 54 LEDs in series and apply 350mA on it, all LEDs would run with 350mA but the string needs a Vf of 113,4v(Cree deepred, 2,1v/350mA).
If you connect 54 LEDs in parallel, you need the 1.890A you said above, but only 2.1V!

Here should be two parallel strings of 27 Cree LED's connected in series, so that the ~670mA are spread over the two strings. This means that the LED's run with max. 335mA at a Vf of 56,7v.
Maybe a little bit more because of the onboard regulation resistors, but not that much.

Please,correct me if I'm wrong, @welight

And Mark, I have a question about the pink full spectrum 5630's I've seen on some boards.
Are these Sanan pink fresh meat 5630 chips or more reputable brand like philips 3014 fresh focus?
And do exsisting plans to offer LED strips with it? Maybe 2ft. Strips like Sammy's F series but with 72 pink/fresh meat/focus LEDs (8s9p) for 22-24v?
Could be used well with the currently trendy strip lamps to complement the spectrum and would surely be a good thing for many users!

@Randomeblame ok i get it 27 in series x2 that explains it... i didnt se any spec on how the 54 cree leds was configured

You say that but it does not appear to be true. I see zero load balancing. Nothing at all. I'm not saying you boards do not work well, they do not NEED protection from thermal runaway. Load balancing would be nice. But saying you have load balancing when you do not is deceptive bullshit.

Fact: Resistors CANNOT do load balancing.
.
Whooooah I feel like a right numbnuts because like Mark that is exactly what I thought and exactly what I have been doing doh:o... I thought using resistors and CV + CC driver was the way to go, seems you have re-educated me thanks a lot:clap:

Mark how about a 2x4 with 2 sol-skins? or 4x4? and hmm is th epread from the solskin depending on wtich way the boards is mounted?

testing results, in 3x3 using COBS on the perimeter to try to balance ppfd

Very nice Mark. But i would like to leave some constructive criticism. Please dont take it as complaining cause i think you have a fabulous product. Its like getting to DIY your own ChilLed or Heliospectra. And if i get you right you can customize them to buyers spec. Am i right, with some kinda MOQ?
However:
1 Why give a parmap on the board and 4 veros at an unknown wattage (per cob and board) and unknown spacing? It makes it very hard to evaluate the board in it self. Theres an abundance of info on cob spread but still no parmap on your board in it self.

2 The blurple spectrum you got is really intersting. Seems to me that it would make for a perfect supplementation, both red and blue in the same string. Also its not like mono blurple, it covers far red and that interesting 680 spectrum (for emmerson effect) as well as having a bit of infra red to get some heat on the plants. Here where i am in Spain we got hot summers and cold winters: hps is still king for a great deal of the year and changing light for half of the year is a bitch. Also if i understand right the blurple chips are cheapish in comparison to the red 660s, the double blurple + red 660 is only marginally more expensive than the 3000/4000k+ 660 reds. I would love a board with say 3000k (or 4000k for that matter) + blurple channel priced slightly over the boards with only 2 channels of white.
But still no info on the chips. A parmap on the blurple spec only would be nice :)

Also: i respectfully ask you to figure out some better priced shipping to the EU region. I cant remember exact numbers but when a i checked out what 1 board (which is all id reasonably get with the little info provided as off yet) i think the price doubled with shipping on a 2 channel board when shipping was added. You got a kickass shipping connection for the US, show some love for us poor guys in EU.

Ideal info ( parmaps, coverage etc), what people need to have to invest in your product:
1 we need to figure out how much 1 board covers. With and without reds. On a wattage that requires no heatsink, minimal heat sink or thermal bedding and a real heat sink, like 5mm baseplate aluminum.
2 how the boards scale or spacing over a larger cannopy: at least here with everyone on hps people are married to their 1mx1m trays, 1 per 600w hps and a lot of people who do comercially do 2x2m islandcannopys (thats like almost 7'x7'). Or another option: how much does 4 board in a square cover? Again, low medium and full power, with and without reds would be great.

Ok long rant, and i ask for a lot of stuff. Sorry if it seems like complaining, i really like your product just wanting more info. But hey arent we all a bunch of data junkies?

i agree with you friend ^^^
Mark, your product looks very good,but a real par test is required for boards only ,using cobs at the test does not reflect the true nature of the board,you might as well throw in a gavita .
Would love to see some real data on these boards,definitely the most sexy product at this stage.
peace and love:-D:-D:-D

Hi Rocket Soul
Totally agree with your points, to be honest being a little selfish as I am going to use this light to do a grow myself, so really getting a bit off track, my goal with this was to actually test where COBS needed to be placed to get an even PPFD across the whole 3x3 area, so to your points,
1. yes the idea is to provide custom builds, spectras for customers, MOQ maybe depending on the blend required and part availability.
2. MAPs for just the Skins will be up shortly, of course this is of more interest than my experiments.
3. We have a delay on the FS light as we need to mod the footprints on the 5630 as the FS leds have a different foot print to the SAMSUNG, but yes really want this as it adds a really nice addition of red/blue ratio/balance and control not possible with just white. The FS chips also can be ordered in several values ie more red or more blue or almost balanced.
4 Shipping to EU, yes we need a better deal, we pretty much use only DHL because they are awesome. to the US, not so good to EU, so will try to find a better solution
5 Coverage, will try to get all the data you have requested up by end of the week
6.Scale, would like more info on this, can you rough out a drawing and email to me, 1x1m is roughly 3 x 3, so 2x2m as you say 7x7, I thought builds were 4 x 8 in commercial, however I dont know for sure? will do some testing on this
Cheers
Mark
