Hey fellas loving the thread with these strips! Chasing maximum efficiency, coverage and spectrum ultimately with the 4ft Samsung H series C strips (3k and 4k), uvb bulbs, far reds (unsure on ratios for uvb, reds etc?)
So if someone wanted 25x 4ft H series C strips what would be the most efficient way to power them? Using a spacing of 30mm between strips the dimensions would be 1120x1200. If someone could help me out with the maths on that it would be greatly appreciated
Any of these ELG series drivers? 220v input BTW. Would that mean 12 strips on each driver?
Edit; also has anyone thought of water cooling these strips? Specifically the Samsung's. Would the heat transfer from strip > paste > aluminum? Could you "peel" off any backing inhibiting cooling to the actual back of the cob? Or even have coolant directly in contact with your modified strip?
What's better; 3k strips, 3.5k strips, 4k strips? Is more 4k better? It seems to have more usable spectrum.. Especially if using reds surrounding these strips?
might also want to consider a constant voltage meanwell like hlg 320-48aHey fellas loving the thread with these strips! Chasing maximum efficiency, coverage and spectrum ultimately with the 4ft Samsung H series C strips (3k and 4k), uvb bulbs, far reds (unsure on ratios for uvb, reds etc?)

i dont think you will be dissapointed....my 5ks are trouble free so far560s FTW. I just received some in the post the other day too. Happy days
Yeah I've been running various Samsungs for a while now and I absolutely love them. No doubt these will be very similar in performance. Diffused light is absolutely the way forward. Orca film is my other fetish for the same reason. Cheersi dont think you will be dissapointed....my 5ks are trouble free so far
Yeah removing heat from the grow space was my main concern, quite unsure how effective the heat transfer would be from a strip as apposed to a cob?Water cooling would be overkill unless you're trying to remove heat from your grow space (as opposed to just cooling your emitters).
Looks like you might squeeze 12 x 4' strips on the elg-200 @ 700mA although the test current in the DS is 960mA and max volt is ~24v so hard to say.
Nothing conclusive about what color temp is better although 99% of folks seem to flower with 3000k/3500k
With supplemental reds maybe you could get away with higher color temp but were all guinea-pigging it at this point.
is supplemental ran the entire time during lights are on? Or only for short times after lights out?
Thanks!
Thanks...I'll read and do my homework.i hope so on the voltage droop....in all reality i could see a 30c TC very easily...
as far as driver offset...just the old fashioned way currently..3 drivers/3 timers...then the sequence will just be: 1x vero 29 4k....on 1hour...then 2x 3070 3500k will kick on for another hour...finally all vero eb,s mostly 3k and a couple 3500k too....then the reverse at the end of the day....
My hope is to ramp up intensity in the plants against an actual vapor pressure curve....this alone wont help me try to meet my goals but a new dehuy is forthcoming....
i am not all dialed in totally on this working but @wietefras really drove it home for me in my ignorance
on the driver offset...if anyone has suggestions for a different direction..i consider this only temporary to collect data....and i have most of the gear to build this too:

nice.recycle reduce re-useHi everyone,
Really enjoying seeing the builds with these strips and other taking off... currently building nice 4ft clone light from discarded flouro housing...
What I was want to know is has anyone found suitable diffusers for the Bridgelux EB series strips?
Thanks in advance.
i feel like i have the exact opposite of what a good vapor pressure deficit curve is on an average basis....Thanks...I'll read and do my homework.
A couple a thoughts. First of all... Kapton tape is a beautiful thing...very functional. In my opinion function always trumps beauty. And if the wires bother you, turn the fixture over, then you have a wire tray and you can tape or tyrap the wires down. Thanks for sharing.It fits the width perfectly. Will need to mount it from the ceiling of the tent though.
I think I'll keep on the lookout for another 18" x 4' fixture and move these strips onto that to spread the light better.
Also I don't like how I used kapton tape. I want to give the magnet approach a try I think that will work well.
I didn't think about it before but it's kind of a hassle that wagos don't have screw mounts. I want to clean up the wiring bit don't have any way (other than tape?) to clean it all up.
Also, this isn't a grounded power cable I will need to switch that, but I don't know where I would attach the ground on this fixture? I guess the bare metal of the casing?

I won't turn it over because it's going into such a tight space I want to maximize every inch of vertical headroom. I think I'll tape the wires down and use screw mount zip ties to secure them into place.A couple a thoughts. First of all... Kapton tape is a beautiful thing...very functional.

aren't the samsung strips 24 volt?might also want to consider a constant voltage meanwell like hlg 320-48a
