Common LED issues and how to solve them

LEDs are without a doubt, a modern-day solution to lighting your home or workplace, but they are not immune to technological faults and defects. Our expert LED lighting manufacturers will take you through some common issues with LEDs and how to solve them to restore their functionality, so you can continue enjoying your fittings without frustration.


The first and most common problem people face with LED lighting is flickering. Many people find themselves familiar with this issue in incandescent and fluorescent lightbulbs, but in reality, LEDs can also suffer from this problem. Without fixing, this can become a serious problem, often causing headaches, nausea and energy fatigue which is most definitely less than ideal for a working environment where LEDs are commonly used. 

LED flickering can have various causes, including voltage fluctuations within the home. When large electrical appliances turn on/off, sudden changes in power can lead to fluctuations in voltage levels. As a result, the LED light, which draws power from the mains, may flicker due to the fluctuating voltage coming through the power supply. 

To solve this problem, have larger appliances that require a lot of power, such as fridges, freezers, and ovens, on separate circuit breakers to protect the other electrical channels in the home from overloading. 

Loose connections and wiring are another common cause of LED flickering. To address this issue, simply tighten the LED lightbulb securely by removing and re-screwing it. Also, consider cleaning any dust from the fixture, especially the connection points, as dust can affect the internal components.

Buzzing noise

There is nothing more annoying and irritating than a persistent background sound that disturbs your day and headspace. While all types of lightbulbs can produce noises that can be distracting, it is more noticeable in LED products due to an overload in the circuit as the LED lightbulb is receiving a slightly higher voltage than it requires to operate. The humming or buzzing sound that LED lightbulbs give out generally indicates that the lights are using a frequency of 120 hertz, a voltage level that can cause the components in the bulb to vibrate or oscillate.  

Although the buzzing can be irritating, it generally does not impact the long-term lifespan of the LED fixture. However, it can indicate that the lightbulb is coming toward the end of its life or that the LED product itself is faulty. 

It is important to explore potential solutions before considering a replacement for the LED product. One approach is to check the voltage running through the socket and compare it with the acceptable voltage range for the LED lightbulb or fixture to determine whether the voltage is overloading the fitting.
