Samsung F-Series Gen3

Yesterday, I thought I liked COBs. After a lot of browsing here, I find myself more attracted to the Samsung strips. Particularly F-Series Gen3 SI-B8VZ91B2022 (1120mm 2-row). I have three 4x4 areas that need an illumination upgrade.....1 at a time. I'd appreciate build suggestions on how many strips to use in a 4x4 and how to power them. I started with the 7 part Growmau series but still find the calculations daunting. Thanks!

If those are what you're wanting to use they're 46V. So either use a 46V driver or a driver that has Constant Current, you'd fill up with as many 46V strips you could until it goes out of its Max voltage range for that drivers specific current.
These strips are rated for 2.24Amps so can definitely do the 2100 and maybe even 2800the next step up in current on drivers 320 & 480.

Be advised the LRS-200-48 or LRS-350-48
Are MUCH cheaper drivers and work just the same as the HLG-240-48/HLG-320-48/HLG-480-48.
They just MUST be mounted remotely, off the fixture, and out of the tent/area to be kept dry.

This should help.

A common rule of thumb with good LED is 30 watts/square foot, or 480w in a 4x4.
4 or 5 strips and a Meanwell HLG-480H-48AB is a good choice to avoid high voltage.
5 strips on an HLG-480H-C2100 (with A, B or AB) dimming would also be good, but the strips would be in series so 5 x 46v = 229 volts.

It depends how much you want to spend......
4 strips min. Meanwell HLG 480h 48A Driver, wire in parallel. 10 amps on driver. 2.5A per strip

5 strips would be what I'd go for. Same driver, wired in parallel. 10 amps on driver ÷ 5 = 2A per strip
I can say the light spread of strips is great, edge to edge of tent.
Go for it!

Thanks Airwalker....I appreciate the advice about the LRS drivers. I like to save when I can and would prefer to mount remotely. Am I correct that the LRS-350-48 would run 7 of the 46v strips? I didn't see a dimmable LRS driver. Is that a significant disadvantage?

Yes, they don't dim, but I rarely ever use my dimming even though it's on all fixtures I've ever built.
7.3 amps on the LRS-350-48 so if they take up to 2.4 per the data sheet, then 7 would EASILY fit. They'd be receiving 1.04a per strip with 7. Just as 10 would be 730ma to each one. You can fit as many as you want. The only prohibiting thing you'd run into is only being able to use a minimum of 3 per driver giving each one exactly 2.4a.

Thanks for the links. The build will come in handy. Why is avoiding "high voltage a good choice"? Will building with 5 strips leave me wanting a 6th? Any idea how many strips it would take to 'replace' a 1000w HID?

Definitely go 5 strips on the meanwell 480 48A I tried 4 and the watts per sq ft adds up but was lacking a bit on the par meter, with the 5 the strip in there it brought it up about 100 on the meter at the same distance, and of course they run cooler at 2100ma Vs 2800, and the A type drivers will go well over the 480 it's rated at, mine at full tilt are cranking out 565 watts

But here's the beautiful thing. They're 24V strips, so if you are using LRS they're cheap, so just get the 24V driver. The 48 I only mentioned cause a lot of people already have them for their 48V board builds.

But the LRS-350-24 has TWENTY NINE(29)
FUCKIN AMPS on it so you can run a ton of strips on it.

Nice you're a Vesta user eh? Id LOVE to see some pics homie.

I thought they were 24V for some reason....
This isn't true. It's hard to keep track of all the different voltages of each kind.

But they're 46V.. but if you used some 24V strips that's use around 1amp of current, you can fit 30 strips on the LRS-350-24.

It's weird to me the 48 has only 7.3A and the 24 has 29A. So if the strips were only 24V and ran around 1a for easy math, you can only fit 14 strips if you ran 2series 7parallel, but the LRS-350-24 you could fit 29 of the fuckers.

Nothing super fancy, f series strips in 3500k, heatsinks USA 2 in profile, HF HD extension/power/remote mount cables lol, 2 of those 480 48 a types and some wagos

Nice looking lights. Is this the strip you used t.ly/03M2J How large (LxW) is that room? Would you do anything differently if you built another strip light?

In a 4x4, co2 enriched environment, how many strips would you consider 'overkill'?

Use 5 strips, 4 gets way too hot to my liking on a 480.

That being said I have one client getting 2.3gpw running the space at only about 350W

Great light! Thanks for sharing. 2.3gpw from 5 strips?

4, five should have even more photons for your power money

Im happy to see you are still posting. And your builds are looking solid.
Can i ask how many sq ft for 2.3gpw at 350w?

4x4
