Eternal LED light. From 12W to 6W for $ 1.5. DIY repair

#ledbulb #DIYrepair #LED
DIY LED bulb repair. Making LED Driver for $1.5. Simple and reliable circuit. As a result, we get an eternal LED bulb!

The essence of the eternal LED bulb is to reduce the load on the LEDs, reduce the operating temperature and assemble a simple current stabilizer in which there is nothing to break. The eternal LED bulb is assembled from a burnt-out LED bulb and radio components for $1.5 - $2

This E27 bulb was installed in a dark vestibule on 05/05/2019, as of today, 08/17/2024, the lamp continues to work, all this time the LED bulb worked almost without interruption. The sixth year has begun ... There is no deception in this video.
