Do it yourself. 2 ways. + 2 ideas.
Why do LED bulbs fail so quickly? Because the thermal mode of operation is selected near the area of destruction of the crystal. So you need to lower the operating temperature. Then the lamp will work much longer.
I checked two ways to lower the operating temperature of the bulb. One is free. Only work. You can short-circuit some of the LEDs with jumpers. And thereby reduce power. So you can repair a blown lamp. The second is costly. But quickly. Add a ballast capacitor to the lamp circuit. Both circuits are tested under the control of an oscilloscope. And two more ideas for self-checking. The light in the house must be eternal! :)
