Haha, no!
These reels are only bare LM301b diod but they are not mounted on circuit boards, lol!
You would be forced to solder thausands of diodes by yourself, lol! No need to mention that you would need printed circuit boards with the right solder pattern and so on. It would take weeks or you need a company with a pick and place bot incl. soldering oven.
Believe me, you want them already mounted on strip PCB's. Hand soldering a few thausand midpower diodes takes probably a few weeks and depending on your soldering skills maybe even more. This reels are no option unless you plan the production in china. Even if money is no problem I would rather take something with "made in germany sticker".
Dunno if it'd even be possible to do it by hand, honestly....

That driver is SO FUCKING COOL
Yes , I have used them in a lot of different setups…. I built a few led lamps with 20 of these drivers for a friend that finally never used them… I am waiting for him to resell me only the drivers...
They were surprisingly cheap..I think about 10 $ each one.. Never see them in eBay again

Italy has a few driver manufacturers that use the same format. Meanwell makes one similar also

Okay so I have 3 options according to you guys:

Plc (never in stock)
Nichia strip (claims to be more efficient than lm301b)
Or h influx (not better than plc or nichia)

Thanks very much for your kind reply. It solves my doubts nicely.
Regarding the drivers, I was planning to use this italian drivers I purchased from export estonia store in eBay about two years ago..
they are about 1000ma maximun and allow the voltaje needed for two germans strip in series at about 33 watts..I have 9 of this drivers , and they are versatile cause can be dimmed by Little switches.
So each strip at 16,5 watts Will be very efficient…. Do yo think they are good drivers? Are this way of dimming good?…This way I will be able to dim each strip to 5 watts minimun...extreme efficiency in vegetative mode…

And another question...which blue leds from led tech and how many will you use to suplement this 100 watts 3 strings lamp with the deeps reds added? I mean those blues that are lacking in the samsungs White spectrum 3500 k . As I have 730 far reds and some 365 UVA in other fixtures and some UVB in reptil CFL I think this will is cover all the spectrum now…
Thanks in advance and greetings from spanish Pyrenees

These drivers are okay but their efficiency is a bit low. 85-89% probably cause of its construction. Efficiency also depends on dip switch setting and when you increase for instance the maximum current the max. voltage get's lower. Its probably impossible to run two strips at only 5w and even if its possible the driver efficiency would be maybe 80% or less.
These "dip switches" are nice cuz they allow lots of LED configs but to have a regular dimmer is a lot better.
An HLG-120 costs ~40€, an ELG-100 ~35€ and an ELG-150 maybe ~42€ or so. These little drivers could be used for additional side lights cause they are pretty small and easy to hide.
You can of course use them but compared to an HLG/ELG driver you would lose ~4-8% over all efficiency. And efficiency is one of your main targets.

The 3500°k spectrum also has enough blue. 3000°k yields always the best and also has enough blue for vegging. More blue would just reduce your yields. When you mix 3500°k with deep-red you automaticly get near to ~3000°k.
You get more than enough extra blue from the reptile bulbs and 365nm UVA if you decide to add them too and has the same effect on stem elongation like blue light. Together with the blue of the 3500°k strips you already have a pretty wide blue range. But also without UVA diodes and UVB bulbs you have already enough blue!

730nm is important for the flowering stage and depending on your area I would create something with at least 5-15w. But use a small extra driver to switch them on and off serarately. I've my far-red light connected to a single channel Sonoff(5 bucks). This way I can use it either in the 2nd half of the flowering stage(when stretch is done) or for EoD treatments to put the gals faster in "night mode".

That's easy then, I won't be doing free tests forever so take advantage of it while you can. If they are in Australia it makes it alot easier too

Yeah, he is an "aussie" too that's the main reason I will ask him if he is interested. The company owner is also a member of this forum and I would keep my hand on fire for him. He put a lot of work into his boards and the pre production boards work already pretty well. The first regular charge of boards is currently in production and have better bins like the samples.
Would make more sense to test the final layouts. Maybe a few weeks until he get them, maybe less.
The boards get assembled in Malaysia btw by a Nichia partner. Nichia have helped him a lot with other things too. Really nice to deal with them...

10$ for 35w and ~90% efficiency(in the best configuration) is not cheap!
You can get an HLG-120H-42B for ~40€ to get the same watts like with 4 of them but you would have at least 4% better efficiency. Maybe you can find a datasheet of this drivers somewhere. But I'm pretty sure they are made like Meanwells LCM series and depending on dip switch settings the efficiency can be much lower.
How efficient an LED fixture is depends also on the driver; bad driver efficiency means lower system efficiency. They are good for kitchens, living rooms or maybe for a few culinary kitchen herbs but I would not recommend using them for flowering crops where efficiency is more important.

Hybridway actually documented well a setup like your proposing. There's a fixture that is straight light strings you hang from the ceiling. He had decent results but found that more light at the top where it counts produces more yield.
Trying to remember the name of that light....
Wasn't it the suncloak?

H-influx driven at half nominal current would reach almost the same efficiency..
Yeah, PLC strips are not in stock but if you order them nevertheless you will get yours with the next arriving order.
Others do the same and thats the reason they are most of the time out of stock. If he get a new charge of strips they are already sold and he can ship them immediately.

Better contact Gene directly via email..

@Randomblame it looks like the cheapest route is to double up on h influx to match efficiency.. but I didn't calculate drivers needed so maybe just getting like 18 PLC strips per pvc to add up to 700w (I know I wouldn't be able to keep 6" away anymore:cry::cry:) and getting like 2drivers per pvc would be cheaper? Please let me know if it's let factors im missing to make your calculation more accurate I do have more detail if needed

My goal is to keep the light in a polygon spread instead of a 4 point "square" spread so I would need at least 5 light points around the circumference but I'm shooting for 9 to reach that max

Think they call that polygon a "nanogan" hexagon would be cheaper, even less strips but now less uniform.ity @ lower heights

I will keep a gate fence around the first 8" away from PVC and then add a second layer 16" away from PVC for ultimate vertical scrog like never before .. only thing I will need to do as a Gardener is keep environment in check & manually the only thing I'll have to do is defoliate .. as the plants naturally grow up, the gate will be angled to where I can bend them outward the more I pull the fence to the light...
This took some thinking lol
