[QUOTE="i13, post: 116201, member: 21708"] I have no experience with RGBMAN or DIYLEDExpress. Most of my pixels came from Ray Wu plus I did one order with benbrown in 2016. The suppliers in China often offer strings with custom numbers of nodes or spacing between them. If you do order from them, try sending an email to request a manual quote because Aliexpress sometimes automatically calculates higher postage costs. Note that you'll probably want to keep your connector type and wiring standard consistent between orders. There are different types of 12V nodes to choose from. This thread has info about them: [URL]https://auschristmaslighting.com/threads/12161/[/URL] Injection every 50 nodes would mean injecting at the top of the tree. Do you have a link to these spools of nodes with power injection wires? I haven't seen them before. I would hope that if they're pre-wired for power injection then they would power inject in both directions. Data is directional but power isn't; that's also why we can power a string at both ends. If you're using just one power supply for the whole tree, you don't need to worry about making sure that you don't accidentally connect the positive outputs of multiple power supplies through the pixels. That said, you might still want to cut the positive line in the pixels half way between each injection point if you use fuses. [/QUOTE]

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