The fault is one I have seen on a number of these types of bulbs. The bulb is “up side down” with the PSU in the neck. The heat from the LEDs and sink goes up and lets the PSU run warm. The smoothing cap then overheats and either vents or just dries out to the point it no longer works.
Symptoms are a slow flashing of the bulb as the PSU struggles to provide and eventually it just stops working.
My solutions -
I can replace the cap (solve the problem but I had to destroy the bulb*)
Ensure the kids turn the bulbs off when the leave the room (Or get the automation to do that for them)
*I have repurposed the LEDs and “brains” in another project where I now have my own very bright controllable LED
Considering the price difference between these and something like the HUE… it’s ok.
They have had run-times of hours which makes them quite warm around the I-don’t-like-to-be-warm parts
Tuya is pretty awesome and absolutely compatible with a little scripting, see
I got like 8 tuya wifi power sockets for 11€ each, 3 RGB LED strips for 20€ and am going to buy 20 RGB LED GU10 bulbs on alibaba for ~7-9 € soon, those prices are hard to beat, all compatible with the tuya api, completely controllable over node js, c#, python and more.
