Why do my LED bulbs burn out so fast?

The most common reasons for LED blowing out are high voltage, bad contacts, use of incompatible dimmer switch, or recessed lighting. Other causes include overheating due to not using the right fixtures, or simply a bad batch of lightbulbs!

Why do my LED lights turn off after a few seconds?





9. Recessed LED Light Turns Off after a few Seconds. When too much heat builds up, the LED can shut down. It happens when you install LEDs in the recessed light nooks, which are not well spaced for LEDs.

Why does my LED bulb go on and off?

If your lamp has a confined space, or if it is a downlight with no ventilation, it can capture heat (heat rises) and the heatsink will not cool properly. Better LEDs have thermal detection and will shut off to spare the LED emitter from overheat.

Why do LED lights not last long?

Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.

Why do my light bulbs keep going out?

There are many possible reasons why a light bulb burns out quickly: The power supply voltage may be too high. Bulbs may be loose or connected improperly. Excessive vibrations may be causing the filament to break.

How long do LED ceiling lights Last?





While incandescent bulbs typically last only around 1,000 hours – barely a year with several hours of use each day – LED lighting is commonly rated to last 50,000 hours or more, which can conceivably translate into decades at the same rate of use.

Why do my LED lights turn on for a second?

A bulb that stays on for a few seconds then switches off is likely overheating.

Will LED lights work in series?

Running a series circuit helps to provide the same amount of current to each LED. This means each LED in the circuit will be the same brightness and will not allow a single LED to hog more current than another. When each LED is receiving the same current it helps eliminate issues like thermal runaway.

Why are my LED bulbs failing?

Temperatures are too high (or too low)
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.

What can go wrong with LED lights?



Most Common Problems with LED Lights

  • Using the wrong current.
  • LED bulbs overheat.
  • Low quality solder and wire bonds.
  • Improper use of LED lighting.
  • Issues with color rendering.
  • Existing fittings and fixtures are incomparable.
  • Light Emitting Efficacy.
  • Overly complicated circuits.

How long do LED bulbs last?

One of the biggest advantages of LED light fixtures, is their extended lifespan. While incandescent light bulbs were built to last around 1,000 hours, the most enduring LED light fixtures have been tested to last as long as 100,000 hours. On average LED light bulbs will not have to be changed for at least 20 years.

How do you make LED lights last longer?

How to make LED bulbs last longer

  1. Avoid cheap, no-name LED bulbs. Low cost may indicate that the manufacturer cut corners on components, making the bulb less able to withstand heat or current issues. …
  2. Don’t use LED bulbs in enclosed fixtures or recessed cans. …
  3. Use dimmable LED bulbs and dimmers designed for LED bulbs.


Which LED bulbs last the longest?

LED Bulbs. LEDs usually have the longest lifespan, often lasting over a decade. Mostly, they are several times better than incandescent bulbs and most fluorescent bulbs.

Does turning LED lights on and off shorten their life?

The operating life of a LED is unaffected by turning it on and off. While lifetime is reduced for fluorescent lamps the more often they are switched on and off, there is no negative effect on LED lifetime.

Does it cost more to turn a light on and off then leave it on?

A common myth about lighting system is that it is more expensive to turn lights on and off, so it’s better to just leave lights all the time. Not true!
