How To Fix Flickering LED Recessed Lights

2 Minutes Read

Recessed LED lighting is an increasingly popular way to make a home or business feel more inviting and welcoming. Not only do LED lights provide a modern, sleek look, but they are also energy efficient and can be used to create a range of different lighting effects. 


LED lighting offers flexibility and functionality, whether creating the gentle glow of a dimly illuminated kitchen or added lighting near entrance doors or hallways. 


Flickering LED Lights Are A Nuisance


But, when LED lighting begins to flicker, it can be very annoying and distracting. Let's explore:


Visible Flickering - Visible flickering of LED Lights is a common issue among LED lighting fixtures. Instability in the electrical current passing through the LED results in a fluctuation in light output. This flickering can be seen with the naked eye and can be potentially hazardous. In some cases, the flickering can cause headaches, eyestrain, and other health issues. 


Invisible Flickering - LED lights are known for their low energy consumption, long lifespan, and imperceptible flickering. However, LED lights flicker in a hidden high-frequency pattern, which can be difficult to perceive with the naked eye. This flickering causes the LED lights to appear dimmer and more unstable than they are. In some cases, the flickering can be so intense that it can cause headaches, nausea, and other problems. Many LED lights have specialized power supplies or controllers that regulate the flickering rate and reduce its intensity.


Various issues can cause flickering LED lights, ranging from a faulty dimmer switch or wiring problems to compatibility issues with the LED bulbs. 


If there is only one LED light flickering, it could mean a few things. First, it could signify loose wiring or a failing switch. It could also be a sign of a faulty LED light or a component in the circuit that is failing. 


When multiple or all LED lights are flickering, the power supply could be to blame. This problem could result from an electrical surge, a loose wire, or an issue with the LED lights' electrical components.

Regardless of the potential cause, the first step in troubleshooting the issue is checking the dimmer switch light controller. If you are using a standard dimmer switch, it may be incompatible with the LED bulbs. In this case, you should update the control to a compatible dimmer switch designed for LED lights. 


If the dimmer switch is compatible with the LED lights, check for loose or broken connections, as this could be why there is flickering. On the other hand, if all connections are secure, the dimmer switch could be experiencing issues that require repair or replacement.


The Wiring Could Be To Blame For Flickering LED Lights


Another common culprit when LED lights flicker is the wiring. Poorly installed or faulty wiring can cause LED lights to flicker, as can overloaded circuits. Loose connections in fixtures, switches, or junction boxes can also cause flickering. 


If the flickering stays confined to one light fixture, it is likely due to a problem with the fixture itself, such as a loose connection or worn-out wiring. However, if the flickering is happening throughout your home, it could indicate an overloaded circuit or a problem with the main electrical panel.

In this case, it is best to contact an electrician to investigate the issue further. LED lights are more sensitive than traditional incandescent bulbs and may be prone to flickering or dimming if there is a problem with the wiring. 


Loose connections, overloaded circuits, or faulty switches could cause this. While these issues can seem minor, they could lead to more severe problems, such as fires or power outages, if not addressed by a professional. 


An electrician can inspect the wiring, identify the root cause of the flickering lights, and repair the issue to ensure your home is safe and functioning correctly. 

The electrician might also recommend any changes or replacements to the wiring system that may help prevent any further issues in the future.


Depending on the root cause and the age of the wiring, the electrician may suggest upgrading to a newer, safer wiring system, especially in older homes. Generally speaking, homeowners should schedule an electrical inspection and safety check at least once a year for homes over 40 years old.
