Thanks for the instruction!
I was using wire and JST connectors to connect each LED strip. However, I want to place the strips in Aluminum diffuser channels and I want the LED strips to be right up next to each other so that when the 'comets' from the 'comet animation' run through the entire 5-meter-length, there's no gap between each LED strip.
So, I'm thinking I need to connect each LED strip directly to each other (no wire or JST connectors), just solder strip-to-strip. In this case, am I still able to add a 14 gauge wire from the power supply to any point on along the LED strip, while soldering each LED strip directly on to another LED strip?
I'm guessing the answer is yes, but just want to check.
