You are mistaken. It is a constant current drive. Reducing the number of LEDs by one will reduce the output voltage whilst the output current remains the same. The power dissipated by the LED module will therefore reduce. The power required from the power supply will also reduce, and assuming that efficiency remains constant, the heat generated there will also reduce. The entire lamp will run at a lower temperature and therefore the life of the remaining LEDs will improve.

In real this not happen

I’ve tried with different applications, believe me , after short time it damage another led
Maybe I’m mistaken analysis for the reason, but believe me, it’s not right jumper the broken led
