I’m from Latvia. I have bought in gearbest Xiaomi yelight ceiling lamp. After first switch the lamp was broken. Only cool white leds works. The seller offer pay for repair, because the back shipping from Latvia to China is to expensive.
In Latvia is no official service for xiaomi.

We are sorry about this, and this never happened before. I wonder what what’s your power voltage? Ceiling light only support 220v by now.

220 V, 50 Hz. Hope you can help me to find a datasheet for this device.
