[QUOTE="David_AVD, post: 69649, member: 94"] I think Phil mentioned somewhere that the P10 panels from Ray (using RGB 5050 LEDs) draw a little under 1A (@ 5V) each on full white. This is true when running them from the BBB + Octoscroller + FPP combination. Mine drew 0.9A max each when I tested them under those conditions. But.... if you're using a different controller each panel can draw up to 2.9A (@ 5V) on full white. I'm in the process of writing code for the PCB I designed to drive these panels (for a non Christmas related project) and am driving them at about 120Hz refresh rate (about 1ms per scan line pair) with very little off-time. The measured light output (all white) of a panel running via FPP was about 1650 Lux measured right up against the panel. The same panel running on my own controller put out approx 5200 Lux. I'm guessing that because FPP can drive 8 outputs via the Octoscroller board, each output is enabled for only a portion of the time. Based on the current draw and light output figures, it seems to be only enabled for about a third of the time. I'm not sure if people will even want their P10 panels to run brighter than the current BBB + FPP combination allows. When you have a bunch of panels drawing up to 2.9A each, the cabling needs to be significantly chunkier to reduce voltage drop to acceptable levels. [/QUOTE]

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