Can Led Christmas Lights Burn Out

Led christmas lights use light emitting diodes rather than filament to produce light.

Can led christmas lights burn out.

Buying christmas light replacement bulbs should always be your last step. And yes led christmas lights do last longer than incandescents. If you find a burned out light you don t have to replace the whole strand. Money and energy savings.

Led bulbs will go out if the semiconductor circuitry of the light emitting diode is damaged. So if you increase the voltage across the led above a certain threshold the current will also increase burning out the led. If someone is experiencing failures in bulbs the industry term is lamps its most likely due to the driver the electronics that power the led. Led christmas lights don t have filaments that overheat and burnout.

And they also don t get hot to the touch so they re a lot safer too. However the rate at which this happens is the real issue. Led christmas lights last longer and provide more color options than regular lights but they burn out on occasion. Led s do not burn out more quickly.

With a diode this relationship still exists but it is not linear which is why in data sheets of led s you will see plots of the voltage and current. Led lights do not burn out in a classic sense the way incandescent lights do but they can go out. They don t burn out like other bulbs. In tests led bulbs didn t burn out after over 4 000 hours while standard light string bulbs burned out at a rate of one to two per strand before half that time.

Modern string lights have shunts to redirect the flow of electricity when a bulb burns out so only the individual light bulb is affected. This new technology makes led lights more efficient durable and longer lasting than fluorescent incandescent lights. Because consumers have been told that led lamps are cool to the touch it is a common question to ask do led lights burn out. Led lights are less expensive to run and last longer than incandescent lights.
