I'm using DS18b20's:
A very clean build. I too have been playing with the eb 560s. I have found that running them at .7a that they raise in temp by just 35F over ambient...if I have then laying on the bench or raised up on spacers. Their claim of not needing a heat sink at test current is true! So yours with the sinks that you have...I think could run max current with ease.Thanks for all the inspiration y'all.

..put together my 1st little veg light for a 2x2....
. 4x 560 5000k strips
. Meanwell lpc 48-700
Two strips wired into series and then paralled, works great...got about a half hour of burn in....

I have 10 of these strips i'm gettting ready to build out into a fixture, how do they do as far as distance? Do they need to be right up on the plants or can they be higher up? Im running them at 1050ma
Is this for veg or flower?
I'm running 4 strips a foot at 700ma and 4-6" below is 700 par plus...enough for me. Very even.
Thank you, hopefully someone in the future will find it useful. Strip lighting is reborn and giving everything a run for its money, look at Robin and Steve, even with good strips available before that, they really drove alot of recent want.....
If you ever decided to flower in that 2x2, you could add a 3k strip beside your existing strip (it would have to move over) and that would be close to the Nextlight spectrum...a proven winner.Thank you, hopefully someone in the future will find it useful.

I am trying to keep at around 50% efficiency, also makes my old drivers usable.....but I noticed that the 3k strips are more efficienct than the higher Kelvin, not by much, but if the LER is the same as other bridgelux offering the 5k 560 strips for example are about 4% less efficient than the same 3k at any current, usually it is the inverse.....
I am thinking of doing a complete 4x4 flower tent with all 3k 1160mm strips....x20 x 22 @500mA....that should put me around 400 watts and still 700+ppfd....
also, I need to do an actual TC measurement, but a close one last night had me about 1 degree Celsius over Ambient right on the board material itself. The heatsinks were almost cold...
.1/8 inch 6060 U Channel
.1/4 inch L Channel
.3 mm Steel rivets [I drilled out a bunch of aluminum ones that had too much flex}
well...I flowered in the 2x2 for about 2 years lol...and I have done several runs of 5k and mixed, not my cup of tea actually. Never has been and I dont understand the logic behind it, which has never matched my actual experience....I actually wish they made a 27ook strip or 625nm supplements.
Merry Wu will do osram ssl arrays for you at a good price, I got a 30 LED "COB" (term used loosely) of 660nm SSL 150s for about $30 bucks
Or get a Toaster Oven and a dispensable solder paste syringe and do it yourself.....although can't beat that price.
it appears to be so new, that meanwell only lists it, but has no spec on it yet.
i didn't think about running them i both series and parallel. When these come out, i may just do that!Nine cobs on ONE driver is getting it done, hell yeah.... You could run 16 of the EB strips in two series channels that share 8 strips and then paralleled. That splits your current to 700mA a string, each strip would be 31 watts, and your effiency would be about 48% at that current....So you probably can push 500 watts of output with this driver alone. [16 x31=496 watts ]
If your effieciency is around 50% thats 1000w territory, in a 4x4 and less than 50% the wattage.....
3x Qbs will fit on that driver when ran in series....
vF is somewhere around 109 volts @1400mA
They would be beastly running around 150 watts each, but thats about 50% effiency for these boards.....
You could also run 6x quantum boards with 3 in series and then parallel the 2 channels....Little better effiency but more upfront cost...much easier to spread than #3 in the same size space....
