Web1 Answer. In the most simple terms: it will kill the LED. However things are really not that simple. 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 ... WebThe force of electricity going into a bulb is referred to as the volts listed. Some bulbs are better suited to one force of electricity than the other.
