LED panel 2

Soldered connections.

"I ran my lights in series just like the info sheet says except I put the resistor on the positive side. This seemed to be more the norm from my research. Different manufacturers put out lights with varying voltages. Mine were between 3.5 and 4 so I used a 100 ohm resistor in series. With 87 diodes there are 29 resistors. I looked at it like 29 lights hooked up to the same power source. I should point out that my simplistic way of looking at and doing this project makes electronics guys cringe, but it works." – Michael Suitor, Pyrite
