Before you go out and buy new ones, take a few minutes to let us teach you how to fix the issue. Thankfully, there are ways that you can fix your flickering or dimming led strip lights.

In this blog post, we’ll provide helpful tips on how to fix led strip lights flickering so that they will continue to light up any surface – whether used as stand-alone lighting sources or as part of an elaborate decoration.

What are the Reasons for the Damage?

First of all, you need to know the causes of damage. The flickering or dimming of led strip lights can be caused by several factors, including:

1. Improper Installation: The led strip lights may be installed too close to the fan or air conditioning, resulting in interference between the two and causing flickering.

2. Poor Power Supply: If you are supplying your led strip light from a faulty power source, it can cause flickering or dimming.

3. Loose Connection: Loose connections can also result in the flickering of led strips as electricity will not flow properly through them.

4. Heat Damage: Heat build-up due to lack of ventilation can lead to reduced performance of LEDs and cause them to flicker or dim.

5. Faulty LED Chips: Damaged LED chips can also be responsible for flickering in certain cases and need a replacement immediately if found faulty.

With the causes out of the way, let’s move on to fixing the damage.

What Will You Need?

To fix the flickering of led strip lights, you will need the following:

  1. A screwdriver
  2. Electrical tape
  3. A multimeter

Once you have all your supplies ready, it’s time to start troubleshooting and take corrective action. Here’s what you need to do.

10 Easy Steps on How to Fix Led Strip Lights Flickering

Step 1. Check the Loose Connections:

Take the screwdriver and check for any loose connections. If found any, tighten them up with the screwdriver and then tape them securely with electrical tape. Don’t forget to turn off the power before touching any electrical equipment.

Step 2. Check the Length of LEDs:

If your LED strip light is flickering, it may be due to increased resistance caused by an excessively long length of LEDs. So measure the total length of LEDs on your strip light, and if it is more than 5 meters in length, shorten it to within this limit. Be careful that you don’t cut the strip too short, as it will reduce its effectiveness.

Step 3. Check the Installation Distance:

Make sure that you are installing your led strip away from other electric appliances, such as fans or air conditioners, which can cause interference leading to flickering issues. Keep a minimum distance of 15 cm between these appliances and the led strips. If the power supply is too close to the light, it can cause flickering issues.

Step 4. Check the Voltage:

Check if your strip light is getting the required voltage for it to function properly. If not, ensure you supply it with the right voltage as per its specifications. Otherwise, it can cause flickering or dimming of the light.

Step 5. Check the Power Supply:

Faulty power supplies can lead to flickering in LED strips, so check if your power supply is functioning correctly or not. You can use a multimeter to test this. This will help you identify if the power supply is faulty or not.

Step 6. Check Heat Damage:

LEDs generate heat while they are in operation and don’t dissipate quickly, leading to overheating of components and resulting in flickering or dimming of LEDs. To fix this issue, install a suitable cooling system. You can also use a thermal paste or heat sink to keep the temperature of LEDs under control.

Step 7. Check the Soldering:

If you have recently soldered components to your LED strip, it is possible that due to improper soldering, certain parts may be loose, causing malfunction of LEDs and leading to flickering or dimming issues. To fix this issue, re-solder all joints with care. Ensure that all connections are secure and tight.

Step 8. Replace the Damaged Parts:

Check for any damaged parts, such as faulty chips or connectors, which are not functioning properly, and replace them immediately if found faulty. This will help solve the flickering issue in most cases. Additionally, make sure that the replacement parts are compatible with your LED strip lights.

Step 9. Use a Quality Transformer:

Use a quality transformer as per your strip lights’ specifications for proper operation and also for safety measures against electrical shocks. It will also help to prevent flickering issues. Another good option is to use a LED driver that will help in regulating the current and voltage for the optimum performance of your LED strip lights.

Step 10. Call for Professional Help:

If none of the above steps work and your LED strip’s flickering issue persists, contact a professional electrician immediately who can help you identify and resolve any underlying issues with your setup. Moreover, a professional electrician can also provide advice on the best way to fix your LED strip lights’ flickering issue.

Following these simple steps should help you fix the problem. However, if the issue still persists, it is best to get in touch with an expert technician who can help you identify and resolve any underlying problems with installing your led strip lights.

6 Additional Tips and Tricks

1. Check the Connection: Make sure that all connections between the LED strip lights and their power supply are secure. Loose wires can cause flickering.

2. Check the Voltage: Voltage fluctuations in a power supply can cause LED strips to flicker as they try to compensate for an inconsistent current. A voltage regulator should be used to keep the current constant and reduce flickering.

3. Check the Dimmer Settings: If you’re using a dimmer switch to control your LED strip lights, ensure it is working properly and set up correctly.

4. Replace the Driver: The driver (or power converter) converts AC mains electricity into DC current – this could be at fault if your LED strip lights start flickering suddenly after installation or during use. Consider replacing the driver if you can’t find any other cause.

5. Check Your Circuit Breakers: Circuit breakers are designed to protect electrical circuits from overloads or faults, so make sure they’re functioning correctly, and the LED strip lights aren’t drawing more current than they should be. If necessary, reset the circuit breaker or replace it with a new one.

6. Check the LED Strip: If all else fails, it could be that your LED strip lights are faulty. Try replacing them and see if this solves the problem.

By following these tips, you should be able to fix led strip lights flickering and get them up and running properly in no time! Make sure to follow all safety procedures when working with electricity, as incorrect handling could lead to serious injury or damage.

6 Things You Should Avoid

1. Avoid Dimmer Switches: Dimmer switches can cause LED strip light flickering, so you should avoid using them if possible.

2. Avoid Loose Connections: Make sure all connections between the power source, transformer, and driver are secure and tightly connected to prevent flickering.

3. Avoid Exceeding the Maximum Load: Don’t exceed the maximum power load of your lighting setup, as this may cause the lights to flicker or dim.

4. Avoid Overdriving Voltage Overdriving voltage can cause LED strip lights to flicker, so ensure that you set up your system with the correct voltage in order for it to operate correctly without any issues or flickering.

5. Avoid Running Long Lengths of Led Strips on a Single Power Supply Run: If your LED strip is longer than 10ft, you may need to split the power supply into two or more runs to avoid any flickering.

6. Avoid Using a Regular Wall Switch: Regular light switches should not be used to control LED strip lights; instead, use a dedicated dimmer switch designed specifically for controlling LEDs.

If your LED strip lights are still flickering after following these tips, then it’s best to contact a professional electrician for further advice. They will be able to diagnose and fix any underlying issues that could be causing your LED strip lights to flicker.
