Anyone else waiting for Samsung strips?

Did you try arrow.com?
Single row 2footers in 3000°k are available but no DR strips in 3000-4000°k. I would ask them for a delivery date because they are still orderable.

Yeah ive tried them all. Singles are no good as my heatsinks are pretapped for doubles.
Doing some quick maths 1x double row f series @60w equals 1x doublerow H-influx series @60w in terms of performance.
So now im paying extra £2 per strip for the same performance just to clear all this stock i have.

Yeah, it's even more in the end.
2ft. SR F-strips in 3000°k are 168lm/w, 23v/1120mA and ~345lm/$(4335lm/12,50$).
2ft. SR H-influx 3000°k is 178lm/w, 22,3v/1000mA but ~242lm/$(3960lm/16,50$)
My F-strip build run the diodes with only 60mA per diode, ~190lm/w(11,8w per strip), and I've paid arount 200$ on strips(20x 2ft. SR, 20% discount, arrow). To get the same effiency from H-inFlux I would need around 400mA per per strip(instead of 700 nom.), ~12,4w. I would need 19 L04 H-influx strips to get the same 240w with 190lm/w effiency, also with the usual discount for larger quantities that's a lot more expensive.
I am very disappointed that Samsung has raised prices for LM301b products so much.

I've also read that Samsung is giving up production of LM561c and concentrating on products with LM301b. Sooner or later we will be forced to switch to the more expensive strips such as Q and H-influx.
Hopefully the prices comes down if they become widely available... although, I do not think it will be much...

Yea I tried that one, goes way over my head. I’m an old grower, the led gardener calc is simple to use. Bummer maybe some one will make one for these, probably I should just stick with the F strips I suppose.

Yeah, that's probably the best you can do. Find a reputable manufacturer and let him equip the stripes to your specifications. Take care of a quality control to make sure only the desired diodes and PCB's are used, and it only has advantages. You can use different LEDs and tune them as you want. Additional reds, no prob's...
Such a product could put you in one row with brands like HLG or Cutter!

You can use the same drivers for the H-inFlux as you do with LEDG's "Example" builds for the F Series Gen 3s.. I was under the impression that these new H-inFlux strips were the way to go...a bit better than the F Series Gen 3s...I guess I should have done my own maths on this...but the F Series have been backordered for months. Undoubtedly, the F Series will be in soon, now that I've gone the other way, lol.

Go to the Ledgardener site and ask him.
Technical questions on LED'S get answered there. RIU is great for advice and opinions. LEDGARDENER is a more specialized source for LED info so I wouldn't doubt that crazy polite Canadian would update his tool for ya.

I got mine from Arrow.Getting fed up with digikey now. Any other place i get get a couple hundred double row f series?
10% discount code for anybody who finds a supplier

I believe the 88 diode strip (L06)is over 6k lumens. The 3900 lumen strip is 64 diodes (L04) and the double row (L09)has 128.

Wtf, shit! Thanks, mate! I've taken the lumens from L04 strips but diode count and price from L06. So the difference is not that high as I thought first because the L04 cost's less.
So maybe only 16 L06 strips were needed to compare but 5800lm from an L06 strip for 24$ means only 242lm/$. So still much more expensive than F-strips lumen's/$ wise.
I will edit my post if it's still possible, thanks!

So... Any grow pics? It sounds like you're saying that these Nichias diodes are superior to Samsung's (for growing), so I assume that you must have plenty of real-world, growing-performance data?
Have you seen the spectrum? It's damn near the same as the sun if I remember correctly. He did say we need tests done so I don't think you really need to go after the guy. Look at hps vs cmh that shows spectrum does play a part with lower effeciency you can yield the same. My understanding is the Fuller spectrum allows the plants to take in more light so say you run 1000ppfd at the tops with 2700k theoretically you could bump that up alot more with a Fuller spectrum. I run lm561c myself but I really want to try that 5k niachi just to see if I can increase light levels without damaging the plants

Not going after him. Just asking for more info. But I remain unconvinced (though open to the possibility) that spectrum matters more than efficacy. Still waiting for hard, real-world data on that one. Same for ChilLED's mixed-spectrum boards (on the spectrum benefit issue). I'll be very happy to be proven wrong, as that opens up many possibilities for builders.
I think it depends what your going for both sides are right effeciency is very important but say you have 200lm/w with a lacking spectrum vs 190lm/w with a super full spectrum that 5% effeciency difference might not matter. And if your space limited running higher ppfd should yield more per square foot. A good example is outdoor vs indoor growing outdoor you can have 1400-1800ppfd and the plants look amazing try that indoor with a less ideal spectrum now you can only run 1000-1100ppfd. I wish chilled wasn't so expensive I would love to try them out

Boys we will build strips of any kind to order, but I am not going to lay out a PCB for 5 pcs, what do you want
Cheers
