Yeelight Simple LED Ceiling Light Pro LED replacement

Hello!

I bought Yeelight Simple LED Ceiling Light Pro (90W) about 3 years ago and now some LEDs in a warm channel had died. I can replace them, as i’m skilled electronic engineer myself, but so far i was unable to find any infromation about voltage and current i need for this model. Tried to use generic warm SMDs, but they flash for a 1-2 seconds and died again. Can anyone help me with info about LEDs?

With all respect,

Alex.
