I bought some RGBW LED puck lights with aluminum track last year on Ali to work into my Xlights Christmas show and use as permanent roofline lights. On the back of each puck is written 2904 and SMD5050. I think the Ali listing said TM1804 also. The seller doesn’t have them anymore to ask. On my WS2811 controller they are always on in color cycle mode. When uploaded to the controller they turn a solid yellowish green. I been my controller only handles WS2811s. Falcon controllers specs state they can handle about everything made, but is $$$. Are the Quin units able to work these?
I just got some UCS2904 RGBW puck lights also from Mattos Designs. I am able to able to get them to work on a Quin-Dig-Quad with SK6812. Just testing on the bench so far.
Did you find a solution for your lights?
