I've successfully flashed my "LSC RGB Ceiling Lamp" using Tuya Cloudcutter and connected it to Home Assistant. This ceiling lamp looks quite similar to another device I did a teardown for: LSC Smart Ceiling Light. It is using the same LED PCB, it uses the same module, but internally is using another MCU module.
I bought this ceiling light a few years ago in the Netherlands at the shop "Action".

The lamp uses a "sm2125" led-driver with data-pin=P24 and clock-pin=P26. I'm unable to read the small print, but this is the only i2c driver which I found to be working.
