Samsung F564B Linear Strip Build
- Thread starter Takeshy
- Start date
Just cuirous how the 36 strips (46v each, 1.12A) was able to be powered by just 3 meanwells? what was the circuit like?UPDATE
All items have arrived. I'm hoping to finish the light this weekend and share with you some pics.
Ignore the item list from older posts.This is the updated version.

how much are these and where can i get them? i see you are using the 1.5 inch strips, so the aluminum u channels of 2 inches are needed, and they are super hard to findAluminium U profiles. I will post some pics as soon as the frame arrives
any cliffs on what made you go with parallel instead of series?
i went with 7 in series. pretty annoying since im stuck with 7 per driver. not sure if i could have saved a lot of money going parallel (fewer drivers possibly)
furthermore, in parallel, i was stuck as to how to get the initial connection wired to all 8 strips in series, sinceo n paper its easy to draw lines, but in reality, i cant really split the driver lead wire 8 ways...any thoughts?

Because the voltage would be insanely high if wired in series. 5 slot wago connectors are the easiest way to split your leads into additional wires.
total voltage drop on a circuit for mine is ~320V or so. any issue with voltage being high?

It's difficult, if not impossible to find a driver that can supply that much voltage. And also, high voltage + high current = risk of electrocution.
With these strips in parallel, you're only looking at 24-48v DC which is pretty safe and shouldnt even be able to conduct through your skin, even though the current may be 10+ amps.
that was my exact experience. went with a hlg480-1400a driver that had 1.4a max, and 343v max.
will consider parallel in the future now that i know that wagos are basically junctions in real life

nice! i would love to do that. i have no idea what a distribution block is or if this is way easier than i think, can you explain?
also, what driver/light is that? curious how the math adds up as i presume all you're caring about is how many amps in the circuit to make sure its within driver specs?

@kdt15 if you're curious, this is how I have my parallel strip builds wired with wagos
Each negative and postive lead off my driver goes to a 5 slot wago, and there are 3x 5 slot wagos per negative/positive side. This particular light has 10 strips. So I have the positive going into the first wago that then splits to 3 strips, then that goes to another wago with 3 strips, and finally the third wago which goes to 4 strips. Then the same thing with the negative lead.
If you're curious, that build in the pic is using an HLG-320H-24B driver (constant voltage is preferred in parallel builds) and they're all in parallel. Since 1 strip is 24 volts, the entire circuit is at 24V. I have them at about 75% of their max current, which is 1334 mah per strip, so the total current is 13.34a.

Nope, they are rated for 15 amps or so. No voltage loss to speak of

"Terminal Strip" is the proper name for them - Here are some from Amazon
They essentially replace the Wago's but are mountable and configurable. Mine are 8 terminal strips configured to 2x4, carrying both + and - to the strips. I run 14g wire from the power supply (just a cheap 24V, 15 A, 360 Watt power supply from Amazon/Ebay) to the two center terminals of the strip on the left (not in picture), and another short piece of 14G from those terminals to the center terminals of the terminal strip on the right. The 6 little silver rectangles carry the current from the center terminal pair to the rest of them. 18g wire goes from the lower terminals to 4 of the LED strips. Because I have an odd number of light bars with 2 strips each, one terminal strip supplies 5 strips instead four. This is duplicated for the nine LED strips on the other end of the fixture.
The wire going from the power supply to the first terminal strip carries 6.5 amps - a bit over half (5/9th of it) of that goes through that terminal strip to the 5 LED strips connected to it. A little less than half (4/9ths of it) of the current goes through the 14g wire to the second terminal strip.

It has already startedWhen's the next round starting ?
Me and my chair are waiting
Only using 1 of 3 drivers. Running at 300W.
1 driver for how many 46v strips?? wow x_xIt has already started
Only using 1 of 3 drivers. Running at 300W.
btw, looking at your metal: is that u channels on every strip, 2 inch width and ~ 2 feet long?
and for the frame, the sides area also U channels or L?
and the center between the 2 strips, is that just a flat long aluminum piece?
i had a lot of trouble even finding 2 inch width u channels - had to get them custom cut for me and ordered which cost more and were heavy and pretty poorly cut, stray metal everywhere
nice! so no cooling involved truly?@kdt15 if you're curious, this is how I have my parallel strip builds wired with wagos

for mounting, each strip seems to be on a solid aluminum stick or are those u channels? and for the frame (the sides) those do look like u channels to connect all the strips together, is that correct?
