What and how many drivers would I need to run these?

my led knowledge is very limited but I recently completed a 480w. cob hack using a couple hlg 240 h-54 b drivers & 6 luminus 50v cobs no matter which drivers you choose try www.octopart.com just type which drivers you want in their search box & they pull up multiple sources for that driver & some of them avoid the tariffs for xlg240h-ab average about $41

So here is where I wound up today... This store on ebay has quite a few different boards to choose from, and he responds to questions...In case anyone has any input, Im gonna pull the trigger on diodes today.

So I am thinking of doing a veg board... There is really no reason to do ANOTHER board for flower, I dont have the space for anything else. Am I missing something here? Any thoughts on better spectrum on veg?
The strips come in a pack of three at 50w roughly per strip (150w) so I was thinking of adding 2x of th blue boards to the blue boosters to get to 250w


Description...
WITH BOTH THE SAMSUNG LM301B AND LM301H IN A
PERFECT MIX OF SPECTRUMS ON THE SAME STRIP

Each Regular Strip Has:
64 Samsung lm301b LEDs in 2700k
16 Samsung lm301h LEDs in 4000k
16 Samsung lm301b LEDs in 6500k

Assuming it was a 48v driver you'd ordered.
If your driver is a 48v driver you'll need to have even numbers of those boards ran in three parallel series of two boards each.
They're 24 v each so two in series would get your 48v of the driver.
I know you'd stated part of the model # of the driver you'd ordered, but not it's FV.

Forgive me, my grasp of electronics is not very strong, but the specs on the data sheet note a wide input range of 100-305v, so I understood that as enough for what I needed. I didnt consider the need to wire in series.

I've seen them e-bay is where I bought my drivers but I bought my 50v. cobs for $13.50 each from cob kits

If I'm not mistaken the xlg drivers handle a range of fv which make them suitable for a few applications in parallel as well as series

I literally just spent 3 hours on the phone with the guy that owns that ebay store. This dude is legit. Just got a serious crash course today. This is what we came up together for the veg board

4 - Sun Board 30mm x 400mm 6500k 96 Samsung LM301B LEDs 2 - Sun Board 30mm x 400mm 3500k 96 Samsung LM301B LEDs 2 - Sun Board 30mm x 400mm 96 Royal Blue 450nm LEDs 2 - 32" length 1/2" aluminum angle 1/16" 6 ft 18ga solid core wire screws for assembly dimmer switch and heatsinks

I was referring to output, not input. Sorry sometimes I can be vague. Lol.
I looked on the sheet and it's 27 to 56v on that one. So yeah, to hit that range it needs to be even numbers of boards to make sets of 48v series.
24v + 24v = 48v which is in range for that driver.
And then those sets ran in parallel to each other

They do, but you still have to be in their ranges.
I was just needing more info is all. Lol.

Yeah, that pic is exactly what I was explaining would need to be done for them to be used.
See how there's 2 of them connected to each other? That's a set of them in series.
Then those sets are connected to the other sets matching poles for a parallel circuit.

XLG-240-H
Rated current is 4900 ma.
The parallel config will split that into two halves, one for each set of series. So 2450 ma to each one if it's ran full power.
1800ma is what they're saying for max power on those sunboards. So you could over run them if not adjusted to not be able to via the lo V set screw on the driver. Then the dimmer would just operate in the range you set with the screw.

He actually eluded to that too on the call, but he says he hasnt tested it himself. He said he couldnt guarantee it because other companies tried, and it did not work all that great. ?

Thanks, sorry for the rapidfire posts and no response lol...I wound up just reading him back what you talked about, he said you were dead on with everything except 2450 ma... He says I will really only be able to drive them to 1800ma ... This is all a little raw for me still... My brain is still throbbing from listening to LED speak for hours on end. So dope he took the time to do that though. This dude loves LEDS like I love weed... Strange.

There was a thought process to this combination btw, he advised 2 3500k, over 2 4000k simply for a touch more red. He says he prefers the internodal spacing with this combo over others. I guess time will tell.

You could get the 3500 ma from an xlg 200h- ab ( cost about $39each) I was afraid of running into what you're facing now I'm just not sharp enough is why I went the cob route because I was reasonably sure I could do it

neither am I.. the guy was able to sort and file my incessant rambling into a coherent thought and piece together what I think is gonna be a dope veg board... well see in a week or so...

Correct, you'll want to dial the driver back so it only gives them the 1800 ma. Then no risk of over driving them. That's that benefit of the AB model.
You can set the top end limit with the screw pot, and then use the dimmer lead to adjust within that range.
Sounds like the e bay guy and I would have a great time chatting. I too love my leds. ???
If I had more budget I'd throw more at it but Ive already got too much. Lol.

Thanks for all the input bro... This dude was something else. My guess would be he would have a great time too LOL, and I thought I could ramble...Truth is though I would MUCH rather spend the money with him than fuckin ali baba. Hes a good ol' boy from Tennessee, and was firm about the fact that he stood behind his stuff. Hes also using samsung reds which is cool for my OCD...
