The star on the 5ft RGB tree uses solid white leds so to I designed adapter pieces to convert it to 12mm bullet pixels and add an additional layer with 5 pixels so there is a total of 25 on one side.
Using just the standard holes works with the native xLights star model of 20 pixels. To use the additional 5 you need to use the custom model based on the layout of the internal 5 pixels.
