[QUOTE="i13, post: 116178, member: 21708"] I'd suggest ordering pixels that are already cut to length but yes, having spares is a good idea. In order to minimise power injection, an option is to choose pixels with 18 AWG wire between them. If you mount the pixels, order them spaced slightly further apart than you need so that they're okay if the spacing turns out to be a bit short. Ordering them spaced too far apart will increase the voltage drop due to the wire length. For the tree, I'd suggest 5V due to the efficiency. If it has 1000 lights, 5V would enable you to run the entire tree from one power supply instead of two or three. I'd expect that you'd need to power the 5V strings of 100 at both ends. If voltage drop still happens, reducing the brightness should help. Power injection isn't too complicated if you do need it. In my display, everything is powered through injection and I don't have anything powered through controllers. It's likely that a Falcon F48 version 2 is coming out this year so you might want to wait. It's planned to support a lot more pixels than the current model. In the meantime, a cheap tester can be used to make sure all of the pixels work. Some of the pixel suppliers sell them but here's an example on Ebay: [URL]https://www.ebay.com/itm/DC5V-12V-Mini-3-Keys-LED-Lights-Controller-Pixel-Dimmer-for-WS2812B-WS2811/193690890749?hash=item2d18e071fd:g:rDkAAOSwKtdfdC1E&frcectupt=true[/URL] Which pixel supplier(s) do you plan to order from? I'm assuming that you're planning to use nodes/strings because you haven't mentioned strips. Is this correct? [/QUOTE]

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