I want to power 15 meters of 5v LEDs around the perimeter of my room. I understand I cant just have one power connection because of voltage drop (and maybe too much current down the length of the strip). The easiest way I can think is do one big run, go around, and connect both ends to power and ground. My supply can handle the load. This way each "end" only needs to go 7.5m.
Will this work? The same strip being powered twice from both ends off the same supply. Or do I need to section the strips and have physically separate connections to power.
