WLED power limit for FCOB strip (lemmy.world)

Pardon a WLED question in the Home Assistant community, but I was unable to find a WLED community in the fediverse.

Regardless, I have this 720 LED/meter FCOB strip, which is 24v strip & I'm trying to figure out what to configure the "LED voltage (Max. current for a single LED):"

Since it's a 20IC per meter & they claim 21watts per meter that comes out to ~1w per IC. But I'm unsure how that converts to mA like WLED is asking for.

Any advice would be greatly appreciated 🤠

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

Thank you!

I guess the second part of my question is I want to confirm that WLED says "per LED" they really mean "per IC".

Yes, they understand an led as a thing they can control. I have an analog strip that is one LED
