I get really mixed up between efficiency in l/w and ppf, but if I’m not mistaken you want around 35w per sq foot for around 800ppf for most lights but it depends partly on the overall quality of the color? (90 cri lenses may have something like 120-130l/w but the color is superior and ends up with a better final product) just wondering if you’re losing efficiency with Samsung for better overall quality?

I also have to check again but isn’t the f strips 140 diodes per strip with bigger dimension diodes?

All of these are just me trying to understand this stuff, I’m a broke mofo and 5-600 is a lot of money to me lol

Yeah, 35w/sq foot is a common recommendation with white light. Others here are far more knowledgeable on the spectrum. BTW, 3500k strips are over170lm/w.

I think the jury is still out on the differences between 80 and 90 CRI, and it's not a huge efficacy difference. Strips are 80 so I haven't really looked into it. I think some mix 80 and 90 at different color temperatures.

What size tent? As for what brand of strips, it might come down to what's in stock. It sounds like you have a pretty good grasp of things, so this might just muddy the waters..... http://ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux/

Proabably going to build for a 4x4 space. Right now I don't have a tent i have my cmh hanging from the ceiling in a 8x10' room. I'm currently only 2 cycles in so I'd rather go slightly smaller and if I need more stuff space I'll upgrade later

And I have a terrible grasp on this stuff! Thank you for the link!

Here is a great DIY strip thread, it coveres all the strips pretty much, and covers all the spaces, materials needed. Just a guideline, but its extremely helpful. It breaks everything down.

So I understand series wiring but I’m entirely lost about parallel, well mostly lost lol. Can someone help me come up with a reasonably ran fb24 (double row) Samsung 40” strip setup with what driver I’d need? I’m looking for around 550 watts, I entirely understand wiring the Crees and Veros in series and matching drivers to those, but the harder I’m trying to learn the dumber I feel lol

So each double row 4' strip is around 100w. So you would need about 5 of them, but that's an odd number, I'd go with 6, you can use an HLG-600h-48
It would give you 574w~

It's not as hard as you might think. Take the voltage of the strip, 46. And find a driver that matches. The hlg-xxh-48 is the closest, without going under.
Then you want 550w. The only driver that will give you that is the hlg-600h without splitting up drivers (you can use 2) and look how many amps it puts out. 12.5.
12.5÷6=2.08A or 2080mA to each strip. I think this will put you closer to where you want to be then with 2 seperate drivers.

12.5÷6=2.09A or 2090mA to each strip. I think this will put you closer to where you want to be then with 2 seperate drivers.

Thank you for breaking it down like that, I read 2 articles and watched 1 video that theymight as well been speaking a foreign language lol

And 46 X 2.090 = 96.14watts FYI ;)

I dont know why I rounded up, it's really 2.083

Lololol I wasn't even trying to correct you, homie. I had just thought you forgot to add that so I mentioned it so he wouldn't get confused, but then noticed you had stated it in your next post. That's funny.

But damn, that's PogChamp right there. 6 strips blowing out a 4X4? Where the Fuck do you get these double rowers??
