6 Most Common Causes of LED Strip Failure

Numerous common & unique causes can damage a LED light strip. Here, I will talk about the six most common causes of LED strip failure.

1. Physical Damage

LED light strips are fragile by nature & they demand handling with care. If you’re not careful enough while handling your LED light strip, you will easily damage them.

The most common physical damages are bending & twisting of the LED strip. You can even damage your LED light strip while cutting them if you are not careful enough & cut them in the wrong place. 

2. Age Issue

Unlike an incandescent bulb, an LED strip doesn’t fuse – it just gets dimmer and dimmer. If you’ve been using your LED light strips for years, it’s normal to see them not working as expected due to their limited lifespan.

Another issue with age is wear and tear on the soldered connection. All of these age-related issues can cause a LED light strip to fail. 

3. Water Damage 

If your LED strips aren’t waterproof, then water can damage your strips by infecting the circuit board – causing them to malfunction. Waterproof LED light strip protects its circuit board with silicone coating & that’s why they don’t get damaged due to water.  

4. Voltage Fluctuations

Voltage fluctuations can cause damage to your LED light strips. This problem can happen due to various causes, such as – power outages, brownouts, or problems with the electrical grid. When the voltage is too high, the LED light strip gets overheated. 

On the other hand, if the voltage is too low, the LED light strip flickers & it’s also a very damaging act for the LED light strip.

5. Loose Connection

The soldered connection between LED light strip sections can become loose over time. You can check whether or not the connection is loose by twisting-untwisting two sections & see if that results in lighting up the faulty strip section. If it blinks the LEDs, your strip has encountered a loose connection issue. 

6. Cheap Quality Product 

Never fall into the trap of extremely low-priced products (LED light strips), thinking you’re getting a good deal. If the product is cheap, your experience will be cheap as well. Basically, you will be getting poor-quality components & they will cause premature or unexpected failure while used. 

LED Strip Maintenance Tips For Avoiding Future Damages

Though you can’t undo the damages that already happened to your LED strip, you can surely avoid future damages by keeping some maintenance tips in mind. Here are they: 

1. Use a Compatible Power Supply

If your power supply can’t produce sufficient wattage & voltage according to your LED strips’ needs, you’ll encounter strip damage sooner or later. That’s why it’s important to use a compatible power supply for your LED light strips. 

2. Keep LED Strips Cool

LED light strips require proper care to function properly. One important aspect of this care is ensuring that the strips are kept cool. If the strips are not in a cool and ventilated environment, they can become warm to the touch. 

This can also damage the strips and reduce their lifespan. To prevent this from happening, make sure to properly cool and ventilate the area where the LED strips are located. It’s especially needed if they will be in use for extended periods of time.

3. Keep Distance Between Water & Strip

If your LED light strips aren’t waterproof, keep them away from water. Don’t keep them in places like washroom mirrors where there is a high chance of water splashes. Consider buying waterproof LED light strips if you want to use them like these places. 

4. Avoid Voltage Fluctuations

You can avoid high or low-voltage issues just by installing surge protectors or voltage regulators. This thing will limit how much voltage should go inside the LED light strips & avoid strip issues like overheating or flickering. 

5. Handle With Care

As I previously mentioned, LED light strips are naturally fragile. You should always handle them with care if you intend for years-long usage. Follow the best practices while installing & maintaining them to avoid physical damage.

For example, don’t bend your LED strip for corner areas and use connectors instead. If you’re planning on using glue to attach your LED light strips, then you’ve to do it very carefully. Apply the glue in a way that it doesn’t get into the copper connection through the 3M tape.

6. Buy Quality Products

Whether you’re buying LED light strips for your TV, reading room or gaming room – always try to buy quality products. These products might cost you much, but you’ll face lesser to zero hassle using them in the long run. 

7. Regular Checkups

Different types of problems can occur in a LED light strip. That’s why you should check your LED light strips regularly to see if all colors are functioning well if the LEDs are blinking or flickering do the diagnostics quickly. 

8. Use a Dimmer Switch

If you’re using your LED light strips in areas where it’s necessary to adjust them from time to time, use a dimmer switch instead of turning them on & off frequently. If you use the on/off switch less, you can surely prolong your LED light strip’s life span. 


I hope this article was helpful enough to give insightful information on fixing LED light strips. I’ve mentioned how you can repair your broken or damaged LED light strips without expertise.

Also, I’ve shown several common causes that could potentially cause your LED light strip to break or damage.

The fixation method mentioned above might not work in some cases. In those cases, you’ll need to purchase new strips again.
