Me too - standard 12V and 5V rails run throughout the house would be great. I even thought about a wallpaper with conductive strips so the power could be invisibly delivered to any part of any room and "tapped" with a push-into-the-wall socket.
- xpe 4y agoThe usual counterargument is: voltage drop can become a problem. Trying to use one big power supply and use DC as your only distribution mechanism probably isn't a good idea. But choosing a DC system for part of the house can make a lot of sense. For one residential new construction room, it can be practical to have one shared power supply rather than one per LED. Say you have a 12 V, 5 A DC power supply. Using a star wiring topology, this can serve 10 lights (at 500 mA) fine with 16 AWG.

- thrashh 4y agoThe wires would be thick asf Not practical
- lazide 4y agoEven 12V over 50ft+ will have noticeable voltage drop unless you have huge wires. 5v? Not even worth considering. And switch mode power supplies are relatively inexpensive and quite efficient.
