The LuxaLight GS8208 high resolution LED-strip with 96 digital LED pixels per meter is a very stable product and is therefore suitable for large installations.
Multiple MaNima Magnus 26 were used to control more than 100000 pixels live via Art-Net. These interfaces are synchronised using the group function.
With large LED installations, you will have to deal with voltage drops. The GS8208 LED has a built-in voltage regulation which reduces the voltage drop.
