all thes new informations :)))

This is just a treath to help me and maybe other to make there decision, what led sorce to chose .
What would you do,or what do you do;)

The space ist Classic, 3×3 and almost 7 high.


Cobs;
-9× luminux cxm32 3500k
-9× heatsink
-1-2led driver meanwell

QB ;
-4× Quantum board qb288 v2 (driver each +-80w)
-1-2× driver?
-2-4heatsinks

Strips ;
-54 ×Samsung series H (h282d) lm301b
(54 strips each at 240-300mA= 5.3-6.7w/total 290-361w)
-Driver(s)?



There is Not a big cost dif. (Can be done around 400$)


I just need to find out what driver i need.

I recommend one Mars reflector 960W led to cover your 3'x3' grow size. It is powerful enough, their spectrum are very efficient for the bloom

H-series strip have LM561c diodes. You need H-influx or Q-series strips to get LM301b. For a 3x 3' area you could use 1ft and 2ft strips in series because Q series run all with same amps, only the voltage is different(11v, 21,6v and 43,2v for the 4footers but these are too long). Each pair would need ~33-36v and you could use a HLG-320H-36A to connect lets say 10 pairs in parallel on one HLG-320 driver. Each strip would run near its maximum current(~890mA, max. is 900). If you like it more efficient you can simply connect more pairs in parallel. With 20 pairs each pair would run with only 445mA and you get the lumen/w output from Q-series datasheet. (198lm/w in 3500°k).

20pcs 1ft and 20pcs 2ft. Q-series you can find here ...

And Meanwell HLG-320H-36As are widely available. Arrow, digikey, rapidled, ... Simply use google..

Nice plant but you can get the same or better plants with half the wattage using efficient LED lights. They grow nice weed of course but I bet your dry weight is below 1,2g/w. With really efficient LEDs you can see results with up to 1,8g/w. For this reasons they are outdated today and you can get them pretty cheap.
Do yourself a favor and try something with more performance next time. A single 135w Quantumboard288v2 kit incl. heatsink and driver is pretty cheap and results above 200g are common with such kits in a 2x 2' tent. 4 of them cover already a 4x 4' area and are use to replace a 1000w HPS.

Oooh man, I wouldnt be Happy if i allready bought it. So THANKS A LOT
I cant find the Q serie :( But i still try.
The link gets me to an empty site.

Ok i found the h influx serie, Thats a Game changer for me 1foot strips 13-14$ 2" 24-25$
Thats Money that i dont have right now.
So the strip lm301b Option is of the table for at least the Next year.


Can you tell me what you would do with my budget(max400$) and my space.
Everytime i think i've got it, i missed somthing

So now a am again Not sure 2hat to do

-561 led strips .
-Qb 288v2 dir hgl / or thes from meijiuled China with extra red diods.
- 9× cmx32 luminus on 40w each

That's all 12 available Q-series strips. Cost only half the costs of H-influx but H-influx can run much harder. Heatsinks are not cheap and I would rather recommend to use more diodes.
You can also use Bridgelux EBgen2 series, 175-180lm/w at nominal current.

Hope this link works for you!

PS, its not an empty page you need to scroll down a bit. There are 12 results 1, 2 and 4footers, 3000, 3500, 4000 and 5000°k.

But there is not really a difference apart from diode count and wattage. Both use LM301b so I would choosed whatever works out cheaper for you in the end.

I have looked for the pries.

H influx 1"" have 64 diods 13$
Ans 3700lm from Data shed
Q-series 1"" 20 diods 6$
https://www.digikey.ch/product-detail/de/samsung-semiconductor-inc/SL-B8V2N70LAWW/1510-2461-ND/8536578



With thes h influx 1"" ×18 would give me almost 1200 diods. Can i run each 1" H influx in 1A with 22,3v
I would have 22w each 1"" . Sound a lot

Yeah, you need two Q-series strips to beat one double row H-influx strip. But with 20 H-influx you would get the 10pcs digikey price with 40pcs Q series you could get the 25pcs price which would be a little cheaper. Especially on a tight budget it could help you to keep the costs in check. You could also use 3pcs 1footers per row instead of a 1 and a 2ft strip. The more you take the cheaper they get.
Maybe its also worth to look at arrow.com (search by part-number), sometimes they offer good discounts or put products on sale. Got my 20 F-strips with a 20% discount last year.
