Your prefix is wrong. This should do it, I guess: 416461003164

Also, you should configure 150 LEDs, not only 50. (Red, Green, Blue)

Use this calculator:

ok changed the prefix.
i used the exact calc you suggested but why do i have to configure 150 leds? i have only 50 hooked up. is each color one LED?

here is the setting on the calc:

You dont, he is wrong.

You set 150 channels and 50 LEDs but you did that in your conf.

The prefix depends on the software you use on the arduino.

41 64 61 00 31 64 is the right prefix for a 50 LED setup running the official Adalight software.
