LEDs have a general life expectancy of 50 000 hrs. If you use your lights for 10 hours a day, this should be 13.7 yrs.

Also, how long should an LED bulb last?

50,000 hours

One may also ask, do LED bulbs go bad? Just keep in mind that even in the right wiring, LEDs don't necessarily last as long as they claim on the package. Kitchen designer Dave Alderman tells Money that bulbs can come with bad built-in electronic drivers, which could lower a bulb's lifespan from 40 years to 5.

Beside this, how long does an LED driver last?

The average lifespan of an LED is often rated up to 50,000 hours. This is about 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen and 8-10 times longer than a typical CFL. If used 12 hours a day, an LED rated at 50,000 hours will last more than 11 years.

Why do my LED bulbs burn out so fast?

Loose or Improperly Connected Fixtures or Wiring Loose wiring in a light fixture or the junction box it's connected to can cause the voltage going to the bulb to vary, which wears out bulbs quickly. Solution: Shut off the power at the breaker, and then remove the fixture.

What is bad about LED lights?

LED lights emit light from the short-wave, high-energy blue and violet end of the visible light spectrum. The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration.

Can you leave LED lights on 24 7?

Basically: Yes. LEDs consume far less electricity than either incandescent or fluorescent lights. Sometimes cheaper LED manufacturers skimp on heat dissipation, so the LEDs may get quite hot during prolonged use and could start a fire. I would run them for 6 or so hours while you are awake and see how hot they get.

What happens when LED lights burn out?

Unless an actual component in the LED fails, they will provide light “forever.” While LEDs do not burn out like fluorescent lamps and other bulbs they will however degrade and dim over time. The diode itself will begin to emit less and less light as the years pass. Still, LED lamps can last over 25,000 hours.

Is it safe to leave LED lights on all the time?

Leaving your LED lights on all day isn't quite as costly, but it'll still cause a significant dent in your annual energy bill. 45 LED lights left on while you're at work will cost you an extra $180 a year. That means, if you flip those switches off when you leave, you could save enough for an annual gym membership.

What happens if you put an LED bulb in an enclosed fixture?


Using an LED bulb in an enclosed fixture when it isn't designed for that may cause the bulb to overheat, potentially causing damage to the light bulb and fixture. Even a little extra heat can shorten the lifespan of the bulb and keep you from enjoying the full value of your investment.

Are LED lights bad for your eyes?

LED light can damage eyes, health authority warns. The "blue light" in LED lighting can damage the eye's retina and disturb natural sleep rhythms, France's government-run health watchdog said this week. LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness.

Can I leave my fairy lights on all night?

No worries even if the light string is left on all night. It is suggested that the light string be turned off when not in use to extend battery life. Be safe and use the battery operated LED string lights.

Is it better to leave LED lights on?

Since LEDs produce light through electro-luminescence, frequently switching on and off has no effect on them. Even though they only use a fraction of the energy of an incandescent bulb, you're still saving energy by turning off the lights, so there's no reason to leave them on when you leave the room.

How do I know if my LED is bad?

To test your LED, touch the tip of the black probe to the cathode, or shorter end of the LED. Touch the tip of the red probe to the anode, which should be the longer end.

What causes led drivers to fail?


It is very rare that agood quality LED driver fails because of a manufacturing fault. In most cases the failure is caused by a problem with the installation, or there are some environmental factors at play. You should also make sure that there are not too many lights on the output of the LED driver.

How do I test my LED driver?

How to Test a Diode with a Multimeter
  1. Connect the black lead to the COM terminal on the multimeter.
  2. Connect the red lead to the Ω terminal, unless your particular model differs.
  3. Turn the dial to the diode symbol on the multimeter.
  4. Turn the multimeter on.
  5. Choose a regular red LED.

What can go wrong with LED lights?

Top Common Problems with LED Lights
  • Reason 1: Loose wire connection.
  • Reason 2: Low quality LED.
  • Reason 3: Loose bulbs.
  • Reason 4: Improper dimmer setup.
  • Reason 5: Power supply broken.
  • Reason 6: High wattage electrical appliance.
  • No flicker LED sports lighting.
  • a. Improper power supply for LED lights.

How do I stop my LED lights from flickering?

LED bulbs don't have glowing filaments. When the dimmer switch goes off and on many times per second, the LED bulb becomes a flickering strobe light. In rare cases, the flickering can be some other power supply issue, which may be the explanation if you don't have dimmer switches.

Do all LEDs need a driver?

Every LED light source requires a driver. Some LEDs already include an integrated driver within the bulb. LEDs designed for household use (bulbs with E26 / E27 or GU24 / GU10 bases and that run on 120V) typically already include a driver. However, low voltage LED light sources, such as some MR- bulbs (MR GU5.

What causes LED lights to fail?


When heat can't dissipate from the heat sink, it can cause lamps to fail prematurely. Also keep the surrounding environment in mind. The hotter the room is, the earlier an LED light may degrade. Because LEDs emit light that decreases exponentially as a function of time and temperature.

Can LED light catch on fire?

LED lights do not emit light from a vacuum as most other bulb types do. Overheating is one of the reasons a bulb could start a fire, but that is highly unlikely to happen with LED lights. They may feel hot to touch, but they produce light at a significantly lower temperature than other bulbs.

Can LED lights cause cancer?

However, analysis of more than 4,000 people living in 11 separate regions of Spain established a link between heavy exposure to the LED lighting and a doubling of the risk of prostate cancer, as well as a 1.5-times higher chance of breast cancer.
