Why Does My LED Light Flicker & 12 Ways To Fix

With the popularity of electric lights in the modern era, there are so many questions asked about their price, their quality or how many samples of LEDs are used for houses and work spaces. Most of you have seen your bulbs flicker before and that resulted in the question: “Why does my LED light Flicker?”. If you want to find out why, if you want to get to the bottom of this problem. This article is for you. Here are some main reasons which explain this common and complicated situation.

Why Does My LED Light Flicker? Reasons And Solutions

The reasons for this problem are also complex, such as the installation is not performed correctly, the faulty bulbs or lack of compatibility. The following are some more reasons that explain this issue.

The Drivers

The role of conducting current and a protection pad are both managed by LED drivers. Unless the drivers don’t get faulty, LED lights themselves won’t be able to flicker. Moreover, it won’t lead to many risks that could be more dangerous than we thought in case the temperature of the bulbs are increased. 

For instance, your LED drivers have trouble functioning because of the low quality light bulbs or high temperature. Solution: Make sure that your LED fixtures have reliable and quality drivers which are able to prevent your fixtures from overheating. Change the old and fault drivers into the ones which are functioning and compatible.

Flickering LED lights can result from the wiring or the bulbs, which are poor at connections. Therefore, the duty of manual handling is responsible for these faults. Perhaps there are some mistakes in the process of placing the fixture at the attachment point.

Not only that, the tightening work should be checked and conducted one more time if flickering LED lights are numbers due to the problems of panel and connection points. The minimum length of all wires is about 6”. If the connections to switches, fixtures or light bulbs are poor, it is possibly because the wires are too short which can lead to flickering situations.

Solution: You should check on your devices closely and change the damaged or poorly connected wiring actively. To prevent your LEDs, also your home from many rísks, make sure the connections and installation are demonstrated properly. 

Dimmer Switches Without Compatibility

Installing a fixture in a circuit with an incompatible dimmer switch. This kind of mistake is made widely by people. Turning the power on and off multiple times in just 1 second is the operating principle of a dimmer switch which won’t affect LED lights. As a matter of fact, the light bulbs can start flickering if you try to carry this mechanism on.   

Some people make a purchase without noticing the labels which are attached to the light bulb. When you can’t figure out which bulbs are dimmable or non-dimmable, you won’t be able to find out whether they are compatible with the dimmer switches or not. 

For example, you use a non-dimmable LED bulb with a dimmer switch designed for incandescent bulbs. It can lead to flickering bulbs or even worse are inner risks. Misunderstanding and lack of attention is the main reason for this reason discussed: “ Dimmer Switches Without Compatibility ”. 

Solution: While installation of a dimming system is conducted, you can do an experiment to find out a minimum dimming level that you shouldn’t go below. For dimming systems themselves, a zero-to-10V or digital volt-dimming system would be more appropriate to use instead of a TRIAC alternative.

Flickering LED light bulbs due to their low quality which are low. You should consider buying other bulbs which are better and more reliable. Of course, like other products, the quality and the price, these factors are obviously meant to be. 

Solution: You should make decisions of buying bulbs which are more expensive. The amount of money you pay could be more than usual, but like we said, money comes with quality, you will be able to make your bulbs lengthen their lifespan, and get rid of any risk caused by low quality products. Moreover, you can help the spaces of yours safer and minimize your electric bills.

The Rising Of Wattage

There will be no LED lights without the factor called power wattage. It plays a big role as a factor influencing the function of LED lights. If you use drivers which are cheap and in case there is an appearance of devices in the same circuit with high capacity loads connected to your LED lights, the better drivers, the more normal the output of the LEDs will be. However, the rest of them will not. The wattage surges which are formed into a cycle can wear the drive out and create the “ behind the schedule ” issue.

The Movements Of Voltage

Flickering LED lights can result from the movements of voltage

Flickering LED lights can result from the movements of voltage. It can happen  because there is something wrong with the electrical supply or the voltage status of LED fixtures is unstable. 

The main reason for the movements of voltage is because your amount of electricity that you normally use is too high or maybe because you use many different electrical devices at the same time. Imagine when you are watching TV while your washing machine, oven, refrigerator are still on. Not to mention the possibility that you use air conditioners and other cooling devices in your room. So the question is can the voltage levels rise sharply, they will absolutely increase dramatically. 

Solution: It’s quite easy, move the devices which require higher amounts of electricity to a 240-volt circuit. If a 240-volt circuit breaker is not available in your electrical panel, additional electrical work will help.

Power Supply Situations

When we mention LED lights, it demands something called: “Stability & Reliability”, which a power supply should have. Otherwise, the light fixtures can become flickering

Solution: The use of a compatible and quality power supply is extremely crucial. Therefore, you should make sure that your power supply is 100% stable and the most important is that they are adequate or compatible. In case it is essential, have your power supply upgraded to a high-quality product.

Old Dimmer Switches

The old dimmer switches which are intended for incandescent bulbs can change the levels of current supplied to the bulbs when the “ on & off ” period is conducted. This may work on LED light bulbs incorrectly which leads to flickering bulbs

Solution: For this problem, we recommend you to change an old dimmer switch made for a traditional incandescent bulb into the one which is created for LED lights. However, we should take the bulbs into consideration. Remember that there are dimmable and non-dimmable LED lights, the dimmer switches are just specifically made for dimmable LEDs and not for the rest sample. Once again, you should check on the bulbs closely before making a purchase. 

Sockets Aren’t Cleaned Up

Just like other stuff in your household, if they are not wiped or cleaned up, there will be dust accumulated on your bulbs and your lighting fixtures can get dirty at any moment which leads to flickering light bulbs too. 

Solution: Light bulbs removal work should be done so you can clean the electrical outlet inside out. The most important task before cleaning the LED socket is turning all the devices’ power off.

The Movements Of Temperature

The performance of LEDs can be influenced by the environmental surrounding. If the temperatures are low, it could take some LED lights longer than usual to emit the maximum level of brightness. In the meantime, temperatures which are extremely hot can result in overheating and flickering bulbs. Therefore, what we need is a system which can manage the temperature and ventilation properly and smoothly.

Solution: Imagine you install LED bulbs without an appropriate ventilation, leading them to overheat and flicker. How to solve this issue? For that being said, provide proper ventilation for enclosed fixtures to dissipate heat or you can take the fixtures with a good heat sink into consideration.

Old LED Components

Solution: You should actively notice the status of your LED light bulbs. In case they are aged, you should buy the new bulbs that can meet long-term needs providing light in a long time. The bulb with a long lifespan can also help you with saving the specific amount of money when the amount of LEDs which you are gonna pay for can be minimized significantly.  

LEDs With Flickering Problem When We Turn Them On & Off

People using smart switches that can manage to do multiple and smart jobs such as adjusting the brightness levels or even controlling the internet ( Wi-Fi ) status at home may have experienced the issue of LED lights that were flickering when the light switches were off. These switches need some back up from standby power to warrant the availability of the modern features as mentioned above. 

Unless the circuitry in smart switches is defective, the neutral wire can be used for sure. LED lights known as being located on negative wire can cause capacitive coupling conditions that can accumulate power in the capacitor. Finally, the circuit of light has the voltage accumulated leading to flickering light bulbs

When the process of manufacturing LED lights is conducted, the products are usually covered with a phosphor material which can turn the blue light into other colors including yellow or white. It takes this phosphor material a specific period of time to be stable and stick to LED light bulbs completely which make LEDs spend a short time flickering after they are switched on. The light bulbs will emit their stable levels of brightness when the phosphor material mentioned above is completely precipitated. This is just one in many parts of LED lights’ operation principle which may not cause any single problem for you to concern about.

The Finale

LED lights get flickering results from multiple reasons from subjective to objective causes. To prevent this problem thoroughly, make sure that you follow the rules and also the ways for the best warranty of your LED light fixtures. 

We hope this article will help you gather much comprehension about LEDs and the answers for the regular question: “Why does my LED light flicker” and how to avoid the issue. If you are facing none of the problems above, maybe take a look at some other LEDs issues and the resolutions:
