Will do. I didn't ask for q series but i will if/when they reply.
Anyone else waiting for Samsung strips?

No, it didn't get cheaper, but it did get considerably better.

Yeah, I've finally switched and use a reptile bulb for that reason. Lot's of blue plus the benefits from UVA/B. My first LED+UVB weed is just ready, cured for 3 weeks in the freezer and I have to admit, it's indeed much better as without UV. (Exact same GP cuttings)

.. like with influx and H-influx series too...
Samsung has brought out a good product as always, but this time they have tightened the price more than usual.
L04 and 2ft. F series should not be far apart as they both provide about the same amount of light (~ 4000lm). But in fact, they cost it's at least 20% more for ~5% better performance! It just annoys me that they try turn the clock backwards. Usually you get more lumens /$ from the new generation, but not this time!
But, it is like it is! I don't think we see significant changes in prices. Maybe I'll take a few when get them with a 20% discount deal from arrow, lol!?

5% better performance is worth a lot though.
You gain only about 10% in efficiency when you double the number of strips. So for 5% increase in efficiency/efficacy you'd need 50% more strips. ie that's a 50% price hike to get the same efficacy.
Or you could run them harder and get more lumen from the same strips and thus reduce the $/lm (also by a lot more than you might expect!).
I always feel it's better to compare things at equal efficacy. At least your running costs should be similar then.

Buhhuhu! Nobody want's to understands me!
If you are looking for a strip that delivers about 4000lm in 3k, you have the choice either to take an F-strip with 4335lm from 25.7w (12.50) or a H-influx L04 with 4060lm from 23.2w (16,50). Of course, the H-influx is more efficient, but the price increase is simply disproportionate. Quantumboard v2's still costs the same 75$ and I'm pretty sure that the profit margin is not much smaller ...

The point is that that H-influx would be a 6000lm/W if you run it at the same efficacy. So you'd need 33% less of them (or 50% more of the F-strips) to fill your space. So, you'd be cheaper off with the H-influx strips.

I understand, it depends on the point of view.
I like it when my new lights are more efficient. I even prefer to operate them below nom. current to make it even more efficient. Last time I needed $200 to get my light from 165lmw to 185lm/w. The step to 195lm/w would cost me over 450€(with L06).
It all depends from which side you see it.
Would you come up with the idea of driving the H-influx really harder just to be as good as F series in the end?
In the commercial field yes, but not for DIY with better efficiency in mind.
I guess I have to accept that the costs increase with increasing efficiency. Unfortunately, the F-Series was only an exception with its high lm/$ ratio. Would I take XP-G3 to realize 195lm/w, the whole thing would probably far more expensive ..
It is like it is and lamentation does not use anything.
I have to wait until I get a good deal or switch to another product. BLX will eventually introduce gen3 EB's, which hopefully will not take much longer. Cree has also become more active in the mid-power area. I'm pretty sure we will soon see more 200lm/w products like Q-strips and then prices will go down.

It doesn't matter what you have in mind. It matters that you compare it on equal terms.
It doesn't matter either if you want to run at a high or low efficacy. In both cases you calculate the design (and thus overall cost) based on the efficacy you want to use. Not the other way around.
Sure if you want really high efficacy then the H-influx would be better suited,but for low efficacy they work just as well (and give you room to use them in higher efficacy later)
Still, you only get better efficacy if you run strips at a wattage that gives a higher efficacy. If you don't want that higher efficacy then who's forcing you to run at that higher efficacy? It's not like test data fixes us to that setting. In fact we rarely use their test settings.

Nevertheless, I find that they have become disproportionately expensive compared to F-strips(gen2 and 3).
You can already get 2ft. Q-strips for $7.86 (25pcs), with AZ/SK bin most probably.
With H-influx to get to the specified values from datasheet you need to use AZ/SJ bin.
But I can not say that for sure, because Samsung has messed up the calculator numbers for LM301b 3000, 3500 and 4000°k(they use the same brightness for 3000 and 3500°k, sometimes the same like 4000K).
But you can try it yourself, you get only matching numbers with these bins.
One could run 2 Q-series strips at 720mA to get the same 32w as from one H-influx L06 and you'll get 0,8lm/w more although you use only 80 diodes instead of 88. ...for less than 16 bucks.
But let's end that once and for all. It's a useless debate.. If they were 2-3$ cheaper I would not have said anything!

What means 1 channel, 2 channels, 3 channels?our strips are 560mm or 2ft, what data do you want and on which colours, below is an order going out with Nichia 2000k, 2700K, 2700k 90 CRI, 4000k and 5000k Optisolis
Cheers

1 strip, 2 strips, 3 strips or what?
Also, do you have 1120mm strips maybe? I have HLG-240-C1050A driver and I need better coverage than with 560mm strips. Or can I wire 10 of them to get the same coverage as with 1120mm F strips?

Yes its what im doing. At 1amp each the L09 h influx should be 2.5+ at system level.

Nope, not from datasheet.
Q-series is 450mA nom. and 900mA max., H-series was 480 nom. and 960mA max. I believe.
Download H-series datasheet from digikey, Q-series is added below.
