We’ve all been there. You walk into a room, flip on the light switch, and are assaulted with an unholy flicker. Why does this happen, and is there anything we can do about it? Join me as we explore the causes of LED light flickering and some potential solutions.
A flickering LED light can be very annoying, making the room where the light is flickering unbearable to be in and necessitating a quick fix. As LED lights function just like a computer, you will be able to notice a malfunctioned LED light immediately as it will rapidly turn on and off. This is referred to as flickering.
Flickering of LED lights can be very disturbing and occur due to a range of technical reasons that cause the LED bulb to keep flickering. If your bulbs flicker frequently, you should investigate and solve the problem, not only to relieve the discomfort they might cause but also, in rare cases, they might lead to an electric-induced fire.
This article highlights 10 of the most common issues that lead to flickering LED lights and proposes potential solutions to the problem.
Why Do LED Lights Flicker? Unveiling the mystery behind LED lights’ flickering
1. Faulty Drivers
An LED driver not only manages electrical current but also acts as a protective cushion. LEDs are supplied typically with one of two types of drivers: either constant voltage or constant current. The constant voltage LED driver is specifically designed to maintain the efficiency of lights that require consistent DC voltage to function correctly.
The constant current LED driver is responsible for ensuring everything functions well in the p-n junction. If the drivers are faulty, they will more likely deteriorate from the heat over time, causing the LED lights they supply to flicker.
2. Loose connections of the bulb or the circuit
If you are suffering from LED light flickers, a common cause is the circuit connections. If the circuit wires were fixed loosely to the bulb, the current flowing through the loose points will cause the light to flicker.
3. Poor Electrical Wiring
Another cause of flickering related to wiring is poor electrical circuiting work, which might occur at different points in the house, in junction boxes, at the breaker in the panel, or at different endpoints. These loose wires can lead to flickering bulbs and retightening the connections can often solve this problem.
4. Using Incompatible Dimmer Switches with the LED lights
Dimmer incompatibility is another common cause of light flickering. Sometimes when using old dimmers installed with halogen fixtures on replacement LED lights, the dimmers could cause the LED lights to flicker. Always make sure that the dimmers used are compatible with your LED lights.
5. Dirty Sockets
The problem with flickering light can sometimes be as simple as accumulated dust on the sockets of the light bulb.
When left unremoved, the dust can pile up in the socket and interfere with the current flow into the bulb, leading to flickering. Regular maintenance and cleaning of the sockets and bulbs can completely avoid this problem.
6. Using Non-Dimmable LED Lights on LED Dimmers
Attempting to dim non-dimmable LED lights using LED dimmers can cause the bulbs to flicker. This method of operation can also reduce the lifespan of the LED bulbs and disrupt their function. Make sure you use dimmable lights with LED dimmers to maintain the quality of your bulbs and avoid flickering.
7. Overloaded Circuits
This cause is not a direct result of the operation of the lights, but more generally of the full energy consumption in your household. If your meter box is fitted with appliances up to its full capacity, and all the devices operate at the same time, this can cause the lights to flicker.
This is because running appliances draw varying amounts of current during their operation, which can strain the full current that the meter box can supply, ultimately drawing some of the currents away from the lights. If more current is needed, the circuits will overload.
You can hire an electrician to check your meter box and its capacity to meet your energy demands. Ensure you get a meter box with a higher rating if your current one doesn’t meet your needs. This will also help you avoid possible electrical hazards.
8. Cheap LEDs
It is wise to purchase and install economic and price-competitive options for lighting. However, what you might gain on the price, maybe lost on the quality of the bulbs. Cheap LED lights generally have a high frequency which can interfere with the operation of the bulb and cause flickering.
Additionally, cheap lights might have sub-standard parts which could cause connection problems and lead to flickering.
9. Surge in wattage
The power wattage affects how your LED light works. If, for instance, you connect an appliance that requires a high power load along with the LED lights on the same circuit, you may experience flickering. This is because repeated surges slowly wear down the LED drivers and cause problems over time.
10. Electric Utility Service Issue
If you are experiencing flickering lights throughout the neighborhood, the problem may probably be a direct result of the electrical utility. Talk to your neighbors to check if this is a common problem and report the issue to the utility.
11. Fluctuations in the power grid
This is one of the most common reasons for LED lights flickering at homes. The most effective way to troubleshoot this cause is by alternating the locations of the LED lights to check if they still flicker.
How To Fix Flickering Lights? Simple Fixes for a Smooth Glow
Flickering lights are not only annoying, but they can also be a sign of a bigger problem. Here are four ways to fix flickering lights:
1. Check the bulbs
If you notice that your lights are flickering, the first thing you should do is check the bulbs.
Make sure they are screwed in tightly and that the contact points are clean. If the problem persists, it could be a sign of loose wiring. Loose wiring can be a fire hazard, so it’s important to get it fixed as soon as possible.
You can either call an electrician or try to fix the problem yourself. However, if you’re not comfortable working with electricity, it’s always best to call a professional.
After some investigation, you should be able to find the cause of your flickering lights and get them fixed quickly and safely.
2. Check the sockets
One possibility is that the bulbs are loose in their sockets. This can be easily fixed by screwing the bulbs in tighter.
Another possibility is that the bulbs are old and need to be replaced. Flickering can also be caused by faulty wiring or loose connections. If you’re not comfortable working with electrical systems, it’s best to call an electrician to take a look.
In most cases, flickering lights are easy to fix and pose no major safety hazard.
However, if the flickering is accompanied by sparks or burning smells, it’s best to turn off the power and call an electrician immediately.
3. Check the cord
If a bulb is flickering, it could be due to a loose connection in the cord. To fix this, unplug the light and check the cord for any loose wires.
If you find any, twist the wires together and screw on a wire connector. Once the connection is secure, plug the light back in and turn it on. If the bulb is still flickering, try replacing it with a new one. In most cases, a flickering light can be fixed by tightening up the cord.
However, if the problem persists, it may be due to a faulty switch or socket. In these cases, it’s best to consult an electrician.
4. Clean the contacts
Over time, dirt and dust can build up on lightbulb contacts, causing them to flicker. In most cases, the fix is as simple as cleaning the contacts. Start by disconnecting the affected fixture from the power source.
Then, use a soft cloth to gently wipe away any dirt or debris from the light socket and bulb. If the contacts are particularly dirty, you can use a cotton swab dipped in vinegar or rubbing alcohol to clean them.
Once you’ve finished cleaning, turn the power back on and test the light to see if it’s still flickering. With any luck, the problem should be fixed for good.
Why Do LED Lights Flicker – Conclusion
Flickering lights can be annoying and even dangerous. If you have flickering lights in your home, there are a few possible causes and solutions.
One common cause of flickering lights is loose light bulbs. The first step is to check that all the bulbs in the affected fixture are tightened properly. If they are, the next step is to check the fixture itself for loose connections.
If you find any, tighten them up with a screwdriver. Another possible cause of flickering lights is a faulty light switch.
To fix this, simply replace the switch with a new one. Finally, if the flickering persists, it could be due to a problem with the electrical wiring. In this case, it’s best to consult an electrician
