[QUOTE="i13, post: 116256, member: 21708"] I unfortunately can't see a wiring diagram or anything similar on the listing for pixels with power injection wires every 50 pixels so I can't provide any further explanation. I'd hope that they inject power in both directions. Thanks for posting it though. I'd also be wary about the wire thickness because it isn't stated. Thicker wires means less voltage drop. You can (but don't need to) power the first pixels through the controller. In the scenario that you describe, I'd suggest cutting the positive wire half way between each injection point with the controller counting as an injection point. You'd put a fuse in each of the positive injection wires with the first fuse being built into the controller. If you're only using one power supply then you'd be able to get away without cutting the positive between each injection point. That said, if you fuse your injection points then I would still recommend cutting it. If you don't cut it then the current has multiple paths available and the fuses can share the load. Injection points need to have a negative wire going to the power supply as well; without this, you're forcing all of the current through the controller's negative output. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
