Just a quick question about controlling power draw.

Just a quick question about controlling power draw. I’m fairly certain of the answer but just need clarification.

I have a large setup of (~3000) LEDs that are wired up in 7x parallel (~400 per pin), I wish to limit the current draw via FastLED software.

Using FastLED.setMaxPowerInVoltsAndMilliamps(5,1000);

Does that statement limit the total amount of LEDs (i.e- NUM_LEDS = 1000mA)

or

Would that limit be for each of the single parallel outputs legs? (i.e- 1000mA draw from each pin)

Thanks for any replies!

That will limit the total, for all pins.

If you give 3000 LEDs only one amp to share, they may not turn on
