Samsung F564B Linear Strip Build

[Have2]

i did some calculations, for 48 strips and it shows me 21A, isn't that to much from a wallet sock? I have 1600w of cobs (32 cobs at 50w each) i think they use only 7-8A... i don't want to burn the house up, or im not understanding something, can someone please help me? thanks

are you guys adding some Deep red or going only with the samsung? Wondering if the deep red is a good addition

Finished these two bad boys for delivery tomorrow. I'm pooped after today, it took about 3 days including building a 4 bar 560mm based one too. More than 300 components each.

That there is 1728 LEDs on two 320W drivers for one tent.

If I add it, it will be as an addon strip or pucks. But, I'd rather talk you into adding an extra strip of white diodes.

Nice build you got there! Nice idea with the screws from side to side.

I'm looking to migrate to leds, i'm hitting a good yield with hps de but well.. if I could save 20% in energy, that would be nice!

if it's 21A, then yes, it's too much, 15ax120v = 1800watts at top, but on the safe side, 80% of it. Why don't you connect it to a 240V line?

The 21A is s the DC output. That's why they use two conductors-a single wire would need to be much larger and wouldn't be very easy to bend.

A friend is having me replace all his 600W HPS unit with my version of the original HLG550, using the same driver but a quarter more diodes, on 5 strips packed tightly together still gives 900ppfd at 51cm

What would you use to replace a 1000W DE over a 6'x6' area? I think Takeshy used 32 strips over a 5x5, would give me a 46 strips converting to 6x6... Is it too much? What would be the best driver to use? This heater starts to piss me off
The PL-lighting 1000w de is 2100 μmol but, how much left with the 40-48" headroom needed... I had a personnal question but can't send private message since i didn't post that much here... I'll get there!

I'd use the double row F Series 4 footers if budget was an issue, as framing lots of bars gets expensive,
I'd build two sets on 320W drivers with 4 strips each, 5 if you feel like investing. that should give you about 29w/sqft
Not extreme but doable, if you want to run CO2 or use high ppfd, I;d rather stick 2 480s on 5 bars each in there, and turn them down a bit,

I don't mind about budget, I prefer to get it done properly than ordering again few parts and so on. As for co2, already using it. I got 1.28g/w last one... reaching 1.5-2 would be unbelievable!

Not sure about the 4 footers (1120mm), I'd have to get 1x1120mm and another 560mm to complete the 6' or a 1120mm is enough? That would left a 14" with no light directly over each side. So assuming co2 and high ppfd, you'd only use 10 strips of 1120mm? Seems low? I'm not sure how to calculate the led's w/sq ft.

Thanks again for your time, really appreciate!

I'm pretty sure it should cover the 6 feet area off the 4" strings, with all that power, you need to hang them at roughly 15 to 18" anyway, and they cast a 120-degree beam each.

Worst case you need to make one long bar with a 2+4' strip on one side and then move the whole big fixture a little to next to it.

Is HLG-480H-24A for each 5 double strips would be ok? I saw you were talking about dimming. Trying to reach a PPFD of the center spot of a 1000W DE in the middle. =) I would past url but I miss one like to do so.. ahah

I'd grab a 48A, it has dimming trimpots on top and works in the voltage range the 4' strips function at.

I think chasing the hotspot value of an HPS is a fool's errand. I'd rather aim at beating the average PPFD levels throughout the tent.

Yes, but having the same ppfd (center of hps) through the whole area would be awesome! I found some thread about ppfd calculation, will take a look at this and also the 48A when I get home.
Xmas is gonna come sooner this year I think )

The B8VZ91B20WW can be run at 2.24A
The hlg-480h-48a output is 480w at 48V and 10A so I won't be able to fully drive the strips right? 10/ 2.24 = 4.46 strips... So going with 5 strips I will have to run them at ~2A (that is considering a 100% efficiency driver, which is impossible). But, I can see that the strips are running at 46V for 2.24A... I'm confused (electrical noob here). 78851lm for each 480 which is 79994 PAR but still confused about the PPFD value.

Thanks for the link!

Was not even able to reply without removing the links in the

I'll need to find some extru. alum in U shape. =) 1 led array will cost around 4 times a HPS DE. and using barely same wattage as the DE, so same heat will be produced but a better PPFD average over the area and no hotspot and no "maintenance" a.k.a, bulb change.

The B8VZ91B20WW can be run at 2.24A

2.24A is merely the test current max current is something like 3.8A

HLG 480-48A will draw up to about 565W at the wall which translates to about 550W....

You should get roughly 90klm, with the unit at max throttle. which is something like 1200 or 1300 umol

You will not be using the same wattage as HPS, it is just that the drivers could be turned open to that much.
I mean I suppose you can but you will likely have problems with light stress.

I have one user with two of these rigs, 5 bars in 60cm, and he loves it, used to run 600W HPSes

So he barely went from a 600 HPS SE to a x > 1000W HPS DE. Do you know his yield with the 5 bars? Would be a nice comparison 600 vs the strips.

He is on his first run with the LED, having swapped out mid grow.
Guess we will have better feedback after the next cycle.

We had a shop independently test a unit and they were blown away...
