[QUOTE="Cranzy, post: 110433, member: 28985"] If you look at the specs for [URL]https://www.aliexpress.com/item/32599191945.html?spm=2114.12010612.8148356.12.36a86dc5AYSU4V[/URL] You can see that the max current is 66MA or 0.066A that is per pixel at full brightness on white. Full string of 100 pixels is then 0.066A * 100 = 6.6A per string of 100, at 100% brightness full white. So generally most people run a megatree at 30% or so as that is bright enough. So at 30% a string of 100 on white will be 2A 16 strings will be 32A total and (12v * 32A = 384 Watts) So 2 power supplies will be enough. The falcon boards you power from both sides (each with 1 of those supplies) You said you will be using all 16 ports on the controller, meaning each post will only need 2A which is good as each port fuse is 5A. You will not need any power injection at all. [/QUOTE]

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