Samsung FB24B Build help

Hello guys new to the forum been following for awhile now and learned a lot from you guys so far. Still quite new to led so want some input on a build I'm looking to do.

Plan on using Samsung fb24b (SI-B8VZ91B20WW) over a 4x4 area. Originally planned 2 separate fixtures with 5 strips each wired in series each running at 1400ma.

Will a HLG-320H-C1400B suffice? Is there another setup that would cover my area better keeping a good balance of efficiency/yield? Is it better to run parallel? Thanks for any help.

Its voltage maxes out at 229V. Five of the 46V strips is 230V. However running them softer at 1400 mA requires a bit less voltage, so it should work - just barely. You'll be running the driver balls out.

Running in parallel is not really better or worse, its just a different method that can add some flexibility it terms of adding or removing strips.

Yea guess I shouldn't push it too hard. Well if I run 6 in a Hlg-320h-c1050b that will be in better ranges and give me about 290w if I did 2 over 4x4 think I'll have good enough output for flowing? I'm not a 100% on the math behind light.

@1400mA(77,78mA per diode) each strip would take only 45,6v according to the calculator tool. That's ~228v with 5 strips and should fit well with a HLG-320H-C1400B(229v).
6 would be too much for the CC version and you need either a bigger driver or the CV version(HLG-320H-48A) to drive 6 strips in parallel.

These are the values you get from one strip, multiply this x 5 and you get the values with a HLG-320. Driver loss is already calculated (95%). ~320w net./335w at the wall! Maybe more because MW drivers are known to deliver a bit more current as indicated(5-8%).

Thanks for the replies. Is it safe to run it that close to max voltage (5 on s 320-1400) and how would that compare running 6 of them softer at 1050ma or 6 on 320-48 running at around 1100ma?
Even thought of doing 3 each on a 185-1400. Can buy 2 out those same price as 320.

I guess my main question should be what is the ideal current to run a fb24b at?

I run 2 fb24b strips on HLG-240H-48B in parallel (that is 5 A driver, so 2.5 A each), two fixtures like that for 2x4 for 500 watt total for that area. I figured I can always dim. At that current (2.5A each) aluminum channel does gets slightly warm, like may be 50-60c but these strips can handle a lot more. In my opinion you really underdrive them, but the bonus is your efficiency will be through the roof at low current

1400 mA sounds really low for fb-24b. And your trying to cover twice the area = not enough light

You could run 6 of those f strips on a HGL-320H-C1050 with room to spare. Usually Test current is a safe bet but if efficiency is what your after then running them softer will get you more lumans per a watt. But your going to have to use the light for around ten years to make up for the increased cost. Personally I would run 5 of those in a 4x4 @ test current. Would be more then enough light.

Hmm read datasheets wrong I was under the assumption that max current was 2100ma guess it's 3600 haha. Well thanks everyone who replied think I got my plan. Now to find all my parts will post again when I finish.

I am using 3 strips per 320W driver

48V 6.7A driver
6.7/3=2.23A max per strip. So, I could drive these strips really hard if the heatsinking works well.
@50% power that is about 1100mA per strip.

Drivers start getting much less efficient the lower the load, so I don't want to go under 50% load.

I intend running the strips at just under 90W each most of the time.

I calculated the difference using a 4th strip and it would take about a year for it to pay off the extra strip in electricity savings.

Trying to go for a clean install with minimal dangly bits.


IMG_20180120_160007_HDRs - Copy.jpg I used ordinary cable conduit on the edge, the type with the clip on lid. Cable is 2 core, split into three wires each side with a large crimp connector. lotsa heat shrinking etc. inside the channel.

Busines end. Probably half an inch of each of these wires will be left by the time the LED strips are screwed on. The masking tape is to mask off the area that needs to get thermal paste and served as a guide for laying the strips to mark the holes.

Nice setup. What area you covering with that? Mine will look similar but 2 strips on a 240-48 total of 4 pairs over 4x4. So they will be 2500ma at max but probably will dim down alittle. Also debating buying 47" by 2" extruded heatsink for mounting just not sure it's necessary.

Very cool how's growth been so far?

have only used it for a month in veg, with, unfortunately some plants that have a slight case of root rot. under those conditions it has performed as well as my veg area would have. have only been in flowering for a few nights, but have a tall mk-ultra pheno, 2 ghost train haze's and bogglegum going. 3 of the 4 should get to 4 feet at least. am anxious to see coverage all over the plant from top to bottom

hope to turn the popcorn at the bottom(with hps) into nicer buds.

check my sig for the current build/veg thread. bout to make a new flowering thread soon

Working on the units a bit.
Need to measure, cut and insert wires for all three strips.
Then apply thermal paste (or glue if you are not using screws) and fasten the strips one by one.
THen I need to screw on the driver and connect the AC and DC side to their respective wires.
I can smell the finish line now.
