DiY - Samsung's strips

[eLod]

i have 9 of 2ft samsung f series strips they have the same voltage as yours. i am waiting on my hlg-480h-48ab. i plan to run them under 1A (maybe 7-800mA), but my space is only ~8 sqft (and i don't grow weed). yours are 4ft long so having 6 of those on one driver so you have 10A max, thats 10/6=1.666A each max, so you should dim them (i think the general consensus here is have more strips and drive them low).

with A you can limit the voltage with Vo potmeter so you don't risk thermal runaway (but if you have 8 strips, many dying is not likely). the B with external potmeter is nice (especially if you can't adjust at the driver directly, eg on top of fixture), eg a knob somewhere. AB is both. there is usually only a negligible difference in their price so choose whatever fits you.

certainly you can mix them and you can wire them however you feel like, its just nice to be able to dim together and etc.

edit: as for stock you can check https://octopart.com/search?q=hlg480h-48&currency=USD&specs=0

I'll check out that Samsung calculator right now. Otherwise, let's just assume the minimum luminous efficacy number on the data sheet, which is 151. 151 x 960 watts= 144,960 lumens. If I plug that into those other calculators I get a PPFD of 839, which is excellent.

Using the Samsung calculator, if the lm/w raise to 180-182, it pops the lumens to 171 000 ~, so higher than 839 ppfd... woot!

Yeah, I was too excited to wait X weeks for backorder to be back in stock ahah I'll switch to another B in few weeks!
Strips are in the house! waiting for wago and drivers I'll pick my alu tomorrow for the frame and the wire... I love DIY project

not sure where you at but again check https://octopart.com/search?q=hlg480h-48&currency=USD&specs=0 there is also AB in stock

Nice man, look forward to seeing the end result. I picked up some cheap 2 ft f-series strips a couple weeks back, but have put that project on hold until I can upgrade some things to have the space to utilize them.

@loco41 4k kelvin ones from arrow?

edit: they are fluctuating price heavily (jumping between 7-8 to 25) but are cheap atm https://www.arrow.com/en/products/si-b8t521560ww/samsung-electronics

@loco41 4k kelvin ones from arrow?

Yes sir. I know it will be a bit before I actually attempt to build anything with them, but I'm happy I grabbed some. I think they'll end up either being a great veg light or a cheap white base light to add some supplements to for a flowering light.

@loco41 yeah the price makes it a no-brainer. i was looking into eb3 builds, when i saw the price and just immediately ordered like 9. they arrived in like a week no vat no customs (and i'm central eu). but again i'm into leafy greens (as in lettuce), so the 4k should be fine for me.

Yea I went a little nuts after putting together my first highlights boards. Since then I have bought way more things than I can even imagine using, but will hopefully get to a place where I can try some side by sides and play around a lot more. I enjoy the growing aspect of things but have gotten hooked on reading about organics and led lighting. I just wish I retained/put to use more of the good info I read before I will forget it again..

I'm sure the 4k's will do great though. More blue is preferred for growing leafy greens right?I'm going to restart some kales and spinach again in some new pots this time under some 3k v1 qb's, again I bought them cause they just seemed like a great price at the time.

Frame is done! Have to stick the strips and wiring..

 

[Have2]

Build is done... Waiting one last driver to connect it... Wondering what is the accuracy of any lux/lumen apps out there... The apogee par meter is a rip off

QB11 & heres the link https://horticulturelightinggroup.com/collections/quantum-boards/products/qb11-quantum-board

lolll

You got me... Looking to add some deep red to my panel! I'm looking at the Q11 quantum board, nice piece! TY!

How many deep red we should add? I do have 16 strips wide... 4 ft strips, 5.5x5.5. 4? 6? What should be the ratio?

You could ask @Stephenj37826 on the DIY with quantum boards thread when the QB11 will be back in stock in deep red (660nm). I'm interested when they and the 470nm blue QB11 will be re-stocked.

Unfortunately it looks like the only QB11 in stock right now are in 520nm green or 630nm red.

I ordered 15 F-strips (3000K). According to the Samsung engine calculator, they're 2 lm/W more efficient at 1A than at 1.1A. That's not much, but there is a big jump in the PPFD calculation at 1.1A. Over a 3'x9' area, 1A= 745 ppfd, 1.1A= 818 ppfd. So I'll probably run them at 1.1A.

The 4 ft? I read somewhere that the cri 90 has a lot more red-ir than cri 80...

I got the 2 footers, they're for my 5.88" x 24" heatsinks that used to have COBs on them. From what I read, a higher color rating index means the individual diodes are more likely to have an exact spectrum match. Anyway, I'm sure the F-strips will be killer.

Did you add a potentiometer? I'm wondering which model would fit for mine.

 

[eLod]

@Have2 for a single driver you need a linear 100k ohm potmeter. for N drivers you need 100/N (kOhm). the meanwell docs should have a chart

 

[eLod]

@CaliWorthington these ones SI-B8V521560WW? where from digikey?

 

[CaliWorthington]

This thread explains it best. For two drivers I'm getting a 50k ohm wire wound resistor linear taper pot.

Dimmer switch for Meanwell HLG?
