All yee light bulbs went bust

I have 4 smart colored bulbs that all stopped working. Bought 3 in 2017, worked for 4 years then stopped working. Bought another yee light 1S that stopped working after a year. All have same symptoms.

  • They don’t turn on
  • When i switch off, the flicker dimly once and go off
  • when i reset by turning on/off 5 times, they change colors showing successful reset but the light is dim and they are discoverable but do not connect
  • before going dead, all bulbs went dim, then eventually died.

Whats the issue here? So disappointed. We have 220v electric connections.
