Why Do LED Lights Burn Out Quickly? 5 Reasons Why

Clink! And just like that, you have lost your LED lights again. Have your LED lights stopped working just as you finished a crucial task? Did you not just replace them? This may be a very annoying situation. I only just had to deal with this problem. It costs money to keep having to change your bulbs so frequently. There are a few reasons why your LED lights keep going out before they should, even if you might not know the exact cause.

The most common reasons for LED blowing out include high voltage, bad connections, an incompatible dimmer control, or recessed lighting. Other causes include overheating due to incorrect fixtures or just a bad batch of light bulbs.

Let us look at the reasons for such and possible solutions for them;


LED lights produce less heat than conventional bulbs, yet they are more prone to overheating. As a result, they may burn out prematurely. To lengthen the life of your bulbs, keep them cool.

First, ensure that the bulbs are not too big for the fitting. You should not use that bulb just because the base is compatible. If you have enclosed fittings, ensure the lights you use are appropriate.

Also, ensure you do not exceed the light’s maximum wattage. Because LEDs consume so little power, this is a less likely source. Yet, as low-energy lighting becomes more popular, more fixtures reduce their maximum load to keep up.

2. Incompatible Dimmer Controls

One of the most prevalent causes of LED bulb failure is the use of incompatible dimming circuits.

To begin, consider that LED lights are not dimmable by design. When installing a light bulb, ensure that the circuit is dimmable since dimmable LED bulbs may be used in non-dimmable circuits but not the other way around.

Second, the reduced power consumption of LEDs was not considered when earlier state-of-the-art dimmer switches were designed. Instead, use a trailing edge dimmer switch.

Finally, dimming circuits may be selective about the minimum and maximum load, resulting in burnout. Ensure your switch is not over or underloaded, and your bulbs will last considerably longer.

Just divide the maximum wattage of the switch by the wattage of the bulbs you plan to use to find out how many bulbs you may use.

3. Bad Connections

When using E14 or E27 bulbs, ensure they are not excessively tightly or loosely screwed in. If the contact points are too loose, twist them one more time to ensure they are secure.

You may have accidentally pinched the socket tab if you put the bulb in too tightly. The next step involves examining the metal tab on the socket. Replace the fitting if it is not seated at a 20-30° angle, or bend the tab into position with pliers. Before you begin, ensure the power is switched off at the breaker.

If the fitting is ancient, the connection points may have deteriorated over time, and it is time to replace it.

4. High Voltage

If all of your bulbs are going out too fast or are too bright, there might be a problem with your mains power supply. Any more voltage, not just for LEDs but for any bulb, will cause it to burn out quickly. This should be around 230v at 50Hz in the UK.

Contact your electrical provider and a certified electrician if you suspect a voltage problem.

5. A Bad Batch

A faulty light bulb may occasionally escape quality assurance or undergo damage during delivery.

If you have tried all of the remedies above and your bulb is still burned out, there is usually a 14-day return policy to safeguard you. Most bulbs come with solid warranty terms for long-term peace of mind, letting you know they are built to last.


You might be shocked to learn that an LED bulb lasts 20 to 25 longer than a halogen and 8 to 10 times longer than a CFL, even if they will not last you forever. You may have noticed that utilizing LEDs significantly reduces your energy costs. Even if they could have burned out, you now know how to look for electrical and wiring issues and other problems you may encounter with LED bulbs.
