I have a fairphone 5 running /e/os, and my previous phone was a galaxy S9+ running IodéOS.
Unfortunately i don’t have time to write a whole review for you, but if anyone have any specific questions about either i’d be happy to answer them when i get time.

I’m happy to help.

I don’t know much about WLED, but from the other comments here it would appear so. And i think it’s also what makes the most sense.

If i’m understanding your question, what you’re looking for is Ohm’s law
Amp = watt / volt
1 / 24 = 0.042
You want milliamps, so multiply by 1000 giving you 42mA per IC

Alternative if the first one doesn’t tickle your fancy.
