| Apr 9, 2018 at 21:33 | comment | added | Norm | You need to be more clear on the configuration - what does "the extra 9 columns" mean? You need to draw out the COMPLETE circuit. And are all the LEDs the same? | |
| Apr 9, 2018 at 20:51 | comment | added | Dylan144GT | No, the PCB layout is exactly what you see in the left drawing, except for the extra 9 columns of LEDs on the right. | |
| Apr 9, 2018 at 20:39 | comment | added | dandavis | @Dylan144GT: no, i think we're missing something, do you not have 4 parallel strings of 14? | |
| Apr 9, 2018 at 19:59 | comment | added | Dylan144GT | Are you sure about this because it is not 4 parallel strings of 14 series LEDs? Or am I missing something? | |
