Hi, I’’m working in a Project, its a heptagonal tunnel

 ![IMG_3514](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/9/9da087d321964ced1212eb406bae3d98b11a47cf.jpeg)  
Each part will use 225 leds so 225x7 = 1,575 leds.

The question is, how many controlers we need it? Or how can control it?

Take a look at [Multi Strip support](https://kno.wled.ge/features/multi-strip/#esp32) in the KB.

In general 1,600 LEDs is not a lot for an ESP32 controller.  
It is somewhat dependent on how much activity/effects you will be displaying.  
As always, sufficient power will likely be a bigger issue than data.
