@Mebejedi, You definitely want the PB on an end with power source or injection point. You wouldn’t want to power a strip at the output side with the PB hanging off the input side without it’s own power injection. I thought I had written about something like this before, and I found your post from about a year ago! If you take a look at the diagram I edited you can see a theoretical scenario where a power supply injects in the middle, and I talk a little about the problems this might cause: > [@Wiring multiple LED strips](https://forum.electromage.com/t/wiring-multiple-led-strips/772/13): > > Hi @Mebejedi, One thing I see with your power injection setup here: [power distribution split segments] I’ve added power quality gradients, basically distance from power. Parts of the strip farther away from a solid power source may have lower voltages than those close to power, which is caused by voltage drop. Voltage drop is caused by resistance, and will change with current draw. It’s possible for them to swing differently than each other, causing issues with data, and glitches, especiall… In short, yes you can inject in the middle and it goes both ways, but if you have separate power zones, its best to inject power at the edges. --- _[View the full topic](https://forum.electromage.com/t/design-help-for-house/1689)._
