Although LED lights don’t “burn out” as incandescents, they can still be turned off. If the semiconductor circuitry of the Light-Emitting Diode is damaged, LED bulbs will stop working.
However, it is essential to consider what could cause a LED bulb not to work correctly.
Electrical surges on an electrical line can cause damage to LED bulbs. Impulses can be caused by lightning strikes, incorrectly used generators, or hydroelectric or geothermal electricity generation. The surges can cause LED lights’ deaths. A surge protector is the best way to eliminate spikes. Make sure it’s an outdoor-rated one.
