The BIQU/BIGTREETECH Panda Lux LED upgrade kit is a quick, no-solder way to massively improve the chamber lighting on the X1 Carbon (and P1/P1S). I kept the original light and added the new bar by looping everything through the supplied little control board, and it all links to the screen control so both lights turn on/off together.
