I haven't had any issues with power delivery. I intended to put thermal paste under these but was in a hurry to get it together to do some testing. I had to use the kapton tape because these strips didn't have enough room to place a magnet fully on any individual strip. Pretty impressed with this one so far.sweet....aluminum baking sheet from the internet? [ghetto snow sled...its been a long winter ]
I wanted to ask you about the ND magnets and how your builds were doing with them. I am guessing that they work fine and don't interfere with power delivery? Which was my greatest worry....I have hundreds and wanted to see your results
Awesome build.
Aha! Cool beans!magnets on both sides (because you are right, aluminum is NOT magnetic) Seems to give enough pressure to have adequate heat transfer.
Are you running them at the test current of 350ma? Any temp readings?Finally got this together:
20 X SI-B8U114280WW @ $3.68 each
1 X HLG-185h-48A

running them at about 300ma right now. Will get some temp readings when I get a chance.Are you running them at the test current of 350ma? Any temp readings?

The driver is 48v, the strips are 24v, so each pair of strips is in series (24x2 = 4. Then each set of 2 pairs is in parallel. Series and parallel wiring is on the background side of the pic. In the foreground I'm running each of those sets of wires to the driver. I could theoretically only have a single set of wires running to the driver, but I don't know what amperage the traces on the PCB can take, so I only ran 2X nominal worth of amperage.Do you happen to have a wiring diagram or a wider shot of the wiring? I'm having a hard time visualizing it for some reason. I'm assuming you're running parallel based on the driver but something looks fucky to me.
