Yo! saw someone chill complain about the build quality of those boards on insta, kinda put me off!
Yo! Ah ok....I'm gonna stick with my original decision to go with the strips anyway. There's little in it in terms of cost except for the import duty which will be unknown until they arrive.
Also the Samsung's are using S7 instead of S6 bin :)
Those SM's look eager to flower!!

Relax man, have a bar of chocolate :D
Hopefully in a couple of weeks I'll be able to buy all I need for my space; strips, driver, silent etractor fan, new filter and a couple of other bits and I'll be ready to go.....can't wait to finally get it set up properly and working the way it should!
When you top plants do you do it between 4th and 5th nodes or 5th and 6th?

Hey stoney,

where did you get this info about the "Samsung's".
Have I missed something?

Datasheets says only it's LM561c but I've seen no data about the used binnings.
If I compare datasheet to sammy's mid-power calculater and use S6/A1 bin, 3000°k at 80mA, which is similar to H-Series current(8s6p, 480mA) I get the 180lm/w(datasheet says 179) and if I use 124mA which is similar to F-Series(8s9p, 1120mA) we get ~168lm/w.
Use these currents also for the other kelvins and you still get the same values according to the datasheets.

The next thing is, S7 is only selectable in the higher kelvin groups >4000°k and CRI70 and I don't believe Samsung would use these greenish looking diodes on their downlight strips.

But maybe I've really missed some latest news, a S7 bin would raise the LM561c to the same level as the LM301b.
If really so, I can only hope my strips which arrived last week are already out of the new revision ...;)

ive never given topping much thought...didnt realise the 4th/5th node ting was a thing! i just top as soon i think they can take it n then keep topping
Fair enough mate....it certainly seems to work for you, however you do it! How many main colas do you get after you top? 2? 4?

pffft per plant liiike 8-10ish? my recent bout of topping in the veg tent i must of made 50 or so cuts. i top everything i can reach as often as i can without slowing veg down too much. i normally flower for 9 to 10 weeks so i have that long to veg out the next run.

@key4 still in veg. hmmmm end of next week maybeee ishhhh. Things have slowed cause ive cooled the room down for the curing plants in the flower tent

It's a bit of a mystery! I came across this http://lithonia.acuitybrands.com/Files/RTLED_Files/RTLED_WPaper_BinningandLED.pdf and it suggests it could be the colour temp. instead of the light output. I'm still confused cos yours says S13 where Rider509's says S07.

Ahh, okay!
But these numbers have nothing to do with the binnings. If you look at the label structure page(screenie) this part of the code shows the LED Maker, S for Samsung, the number behind is probably the factory number where it was produced.Screenshot_20171028-132651.png
