Top best answers to the question «What happens if you put too much voltage through an led»

Simply put, too much voltage kills the LED. Therefore, if the voltage deviates more than 10%, the LED bulb is fused off… Subsequently, the electronic parts inside the LED bulb get damaged from the voltage spike.

First off, an LED is a current driven device, not a voltage driven device. That is, it doesn't really care what the voltage is, but it does care what the current is. Of course, too much voltage will kill it - but too much current, regardless of the voltage, will kill it.

Knowing the correct voltage is important because applying too much voltage across the diode can cause more current than the LED can safely handle… LEDs typically give off less heat and use less power than an incandescent bulb of equal brightness. They also last longer than equivalent light bulbs.
