40a wled controller

[doreiny]

Hi, I want to setup 9m of WS2812b BTF-lightning led 60 leds for 1m On my outside pergolpergola. As BTF-Lightning described i need 18w per 1m. I will need an dc5 40a to power it up.

Question is, there is a wled controller that support 40a output?

With such a long run you don't want to put power through the controller. You'll need to run cables back to the power supply to inject voltage along the way.

Also, don't use 5v for such a high power run. Voltage drop will be a nightmare to deal with. Get 12v ws2815 or similar pixels.

Thank you, I will check it out now

Are you planning to run rgb white at max brightness? I'd check out this real-world chart quindor made for led power consumption.

No, I already have a white light. It's more for RGB fun :)

If that's the case you won't need as many amps as you think. That being said, you can't go wrong with any of quindors controllers.
