Only 134w net. in a 2x 2' tent sounds really good, especially with +850μMol/s ppfd...
Have not thought that they are so fast available..

You could adjust the design, to have a complete uniform light. Run the sides harder, than the middle, for example. I am planing to have atleast two driver, for different color channels (even in flower 3k+5k) to adjust from 50-100%. I really love these small 1‘ strips (using eb series myself), they are soo handy. And with these diffusor sheet randomblame posted lately, I can imagine some easy water proof construction, and some awesome uniform light!

I think it's easier to space the strips a bit more in the center than try to adjust the current.
What are these diffusor sheets randomblame posted? I couldn't find them.

They are called LightShapingDiffusers and are is nothing else as a fresnel lens, you can get in different beam-angles.
They are already used in a few lights for instance in Grownotherns Holographic Series.
They are moslty used by Dutch Passions forum users and are 75w LED lights(blurple+white LED mix, 64 brand diodes) with 3 different diffuser(40, 60 und 90°, for different areas and heights).
@Tang opens up a few threads a few years ago. Heres a vid with two of them over a blueberry kush:

The f strip is a double strip and produces twice the lumens ? correct ?

F-series strips come in both single and double rows of diodes.

Every other grower that used those panels had mediocre results, tang getting those numbers he did with 9.6w per sq ft in flower threw up a lot of red flags in here, he bounced soon after.........his runs weren't replicable by other skilled auto guys, ever......hmmmmm.
nice catch..............turn on, tune in, drop out

here is a report from one of my suppliers with testing of the LM301B diode. I had considered designing a board to use with the LM301B but the numbers were not there for me.
The numbers show 212lm/w fr LM301B compared to 200lm/w for LM561C at a cost increase of 33% over the LM561C.
I stayed with the LM561C until prices drop considerably.

I saw his threads back then as he tried to impress us with his results. It did not take long before he had painted his sails and pulled off, LOL!
Just wanted to make clear what diffuser it is.
I do not think they are helpful with stripes or qboards, because the light is already very diffuse. No need to make diffuse light even diffuser and lose another 6 or 8% PPF, better use some 2" wide reflector sheets along the 4 sides and increase your PPFD by a few %. IMO, of course...!

Ah, forgot you where here for the tang show and tell; ).......... yes diffuse light, just being dramatic, ha ha. I don't think cannabis benefits from it, imagine growing corn under diffusers!? Take all the light they can get, heavy nitrogen feeders, much like our ladies.

So, actually even only 8,2lm / w difference at 65mA...
I agree to the first and last, but I firmly believe that all plants benefit from diffused light, simply because it can penetrate in deeper areas and shade is largely avoided.
But there is no need to make already diffused light even diffuser. IMO, QB's and strips offer already diffuse light because of the multiple diodes/angles and plants would not benefit with an additional diffusor.
Agreed!Damn Brother P Saying Corn Doesn't Grows Well Under Diffuser's Is A False Statement !! What Do You Call Cloud's?? I Rest My Case
Back in the 80's I have hidden many beautiful ladies in milky foil greenhouses and they've always done better as my outdoor plants.

lol, clouds, good one.....................America is corn country for a reason lots of land, water, chems, sunlight. High DLI plants possibly performing "better" with diffuse light is due to other aspects=lower temps, higher moisture content imo. Indoors that's a solvable issue.
Show me the studies gentleman!====with cannabis
. Lets see some 10+lb plants under diffuse glass,hoop house, high tunnel,etc. Plenty of them outdoors in full direct light. Stick some diffusers on your cobs and get back to me how it compared to bare. Uniform light(strips/boards) does have it's benefits indoors IF it doesn't cut the ppf/w. I'm all for hanging reflective material because it doesn't affect the light source(s)output ....but diffuse lenses, filters, coatings do.

You have to remember that he runs his lights 20-4 so those 9.6 w/sq foot is like 16w/ sq foot at 12-12 in regards to DLI. With specialized spectrum and genetics on point, aswell as running the plants "individualized" instead of all your plants on the same schedule it is still possible but maybe not plausible.Every other grower that used those panels had mediocre results, tang getting those numbers he did with 9.6w per sq ft in flower threw up a lot of red flags in here, he bounced soon after.........his runs weren't replicable by other skilled auto guys, ever......hmmmmm.

Also a lot of people has bolted from RIU led section in the last year(s) as this place grown less enjoyable. Nobody here doubts Supra just cause he aint around here anymore...

Did you know his older vids, where he used 300w Apollo LED lights with generic blurples?
I mean this 6 x18 LED-pucks in red housings, 180w from the wall, which you could buy also on Alibaba a few years back..? He changed two of the pucks with white Luxeon Rebel pucks and called this an ultimate upgrade.
He got nearly the same results using 2 of this 180w lights also in a 20-4 shedule. I belive, it was a AutoExtreme grow, Dutch Passion genetics, as always.
Later he switched from 2x 180w to 2x 75w and got nearly the same results..
TaNg, was of course payed from Dutch Passion, because we have a grow magazin, called THcene and there was an interview with him maybe 1-1,5 years ago. He described himself as a freelancer, product tester and as a long time friend. Unfortunately I disposed of it with the waste paper
but in summary, one can say he is a lying big-mouthed showman.
He only did advertising for the lamps, in whose development Dutch Passion by the way was also involved.

I agree, defo suspicious an unplausible but i dont think being involved with comercial interest is in it self discualifying, we have a lot of decent advertisers here on riu. Anyways, maybe get this thread back to q-strips

Many pictures from his plants are still used on DP's website. If he had said that he works for DP everything would have been okay. But so, I call him a liar.
But you're right, back to the Q-strips ..
