First diy setup, need opinions & help. Please.

I think you're going to want to wire in parallel, otherwise your voltage will be very high !

I made a light that is approximately equivalent to one half of what you're looking for, but I used 6 of the 2' F series double row- same number of diodes as the 4' strips. I'm running it soft- around 300 watts. See here-

viewtopic.php?f=11&t=784

I wouldn't worry too much about reliability and failure- these leds are pretty reliable, and the Meanwell drivers are top notch.

Nice build. I'll have to cross my fingers and hope the Fb24b shows up. No matter how differently I go about achieving the same output. Running 4 of those strips in a 4x4 at 70% power just can't be beaten. The eb gen2 series doesn't even really match its performance. Lol.. I've spent all day studying both data sheets plugging in data into light and electrical calculators. Sighs such is life...a day late and a dollar short. So hats off to the work put in on the suggested builds on the build page.

Here's a nice veg bloom build working off my next build I will do.

Here is the supplies. This is a 2.5×2.5 light build. So you would build 4 of them.

6 - 2' vesta series. $59.46
https://www.digikey.com/product-detail/ ... ND/7899252

4 - 2' eb gen 2 3500k. $26.2
https://www.digikey.com/product-detail/ ... ND/7907663

Hlg-185h-c1050b. $51.32
https://www.digikey.com/product-detail/ ... ND/7703966

Hlg-240h-c1050b. $62.37
https://www.digikey.com/product-detail/ ... ND/7704010

Total. $199

Run the six 5000k sides of the Vesta's with the hlg-185h-c1050 for. 146w. Or get the Hlg-240h-c1400b for 212w of veg.

Run the six 2700k sides of the vesta, and the 4 3500k gen 2s for 227.2 watts of bloom.

Or you could cut out the eb gen 2's and run the 5000k side and 2700k side on an hlg-185h-c1050b for 146w of veg and bloom separate. Or an hlg-240h-c1400b for 212w each.

Total. $162.1-$184.2

You can get two 25k ohm potentiometers to dim the veg bloom separate on the whole tent, or get four 50k ohm potentiometers to dim the veg bloom separate on each half the tent. Or get eight 100k ohm potentiometers to dim veg bloom on each side of each light.

If you can source the rest of the stuff needed, it might run around $1200 USD.

Here's a build using 2' eb gen 2's 3500k 218w

11 2' eb gen 2's 3500k. $72.05
Hlg-240h-c1050b. $62.37

Total. $134.42

[sdfoster22]

A build with 3000k gen 2's from arrow 218w

11 2' strips. $107.25 ($116 without 44 piece order)
https://www.arrow.com/en/products/bxeb- ... /bridgelux

Hlg-240h-c1050b. $57.80

Total. $165.05. + free shipping

Shit, these are all for a 5x5. My bad. If these intrigue you, I can work a 4x4 build up for you.

Eb gen 2's are just as good as the F series. People built lights with the gen 1 ebs and say they work just as well as the F series.

[sdfoster22]

A 4x4 build using eb gen 2 4' 3000k strips from arrow 558w total. Run 2 4x2 setups or 1 big light.

14 gen 2's. $265.16
https://www.arrow.com/en/products/bxeb- ... /bridgelux

2 HLG-320H-42A. $185.52

Thank you for taking the time to put that together. I'm probably gonna replicate the single row F series build from the build page for 4x4. It's not the double row that I really wanna try but looks to give similar output. Only thing has me stumped is ..the build has the hlg-480h-48a Driver listed ..while the calculator lists the hlg-600h-48.

This is because the A version is a bit more powerful than the B version and can provide up to 500w.

Again, I think that buying more strip & less aluminum profile is probably the way to go here (more than in the guide). You'll have more light uniformity, penetration etc. And you will be able to put your light closer to the canopy because they'll be running cold and because of the high number of strips, the beam angle won't be a problem.

Option 1) 10 lt-fb22b run around 50% driven by a hlg-480h-48a?? Should provide plenty of coverage at a low percent keeping the heat low.

Option 2) 20 lt-fb22b run around 25% same driver??

If option 2, I might as well just wait it out and purchase 10 lt-fb24b when available and save about $70

Thoughts? Opinions anyone? Many thanks in advance, and I greatly appreciate everyone who's taken a moment to help.

It really all depends how much your electricity costs, how hard of a time you will have getting rid of the heat, and how much headroom you have for the lights.. If you have a good exhaust fan and electricity isn't too expensive, running the strips at 50% definitely won't create as much heat as a 1000w hps from what I've read. (Correct me if I'm wrong) so go with option 1, only if you have enough headroom. If you don't have a lot of headroom for the lights, no good way to exchange minimal air flow, and electricity is really expensive then go with option 2.

Thank you for the response each area has good ventilation not just thru scrubbed air thru inline fans, but also regular fans.

Both options run appropriately 9amps at around 400watts. So cost should be relatively the same for electrical. The difference is the diode quantity, and percent being driven. Also the $70 price difference between 20 strips vs 10.

[sdfoster22]

Yes. With 20 strips, they will run cooler, you'll be able to move the light closer to the canopy. But with your setup, I think option 1 would be fine. Good luck man.
