Awesome, this clears everything I needed to know about, so thank you for that! One last question... do you have any recommendations on the size of the wire I should use?
I currently have 300 LEDs (12 Volt WS2812 strings) powered by a 15 Amp supply based on the calculated rating of 60mA for each LED at full-power white. What I got when I measured the actual current draw was half that. (I suspect that this is from using 12V LEDs as opposed to 5V LEDs.)
18 gauge is sufficient for my project, and at the end of a 300 LED series of strings, I am only seeing a one-volt drop. 12.5V at the PSU, and 11.5V at the end of the LEDs.
Well, for 12 V LEDs, three per individual string, it is clearly 60 mA per three LEDs, isn't it?Which is presumably to say that you are powering the LED strip itself at least at both ends?
Post your code, fast led does have methods to limit current draw in the software, depending on options you set in setup.Also, you may be getting voltage drop along the strip or from the powers supply when you go full white, you would need to measure the voltage at the strip while it is full whits to see.
