Why Do LED Lights Flicker – How To Fix Flickering LED Lights

Flickering LED lights is a common problem but have you ever wondered why LED lights flicker?

Simply explained, LED bulbs flicker when their light output fluctuates. This fluctuation occurs because your dimmable light-emitting diodes are engineered to turn on and off quickly.

Although many people quickly assume that this indicates that the LED lights may fail. Or that the LED lamp is of poor quality, which is not always the case.

There are various reasons why your LEDs might be flickering and we are here to tell you how to stop it.

Why LED Lights flicker?

What most people do not know is that all mains-powered light sources flicker – whether incandescent, halogen, fluorescent, or LED. The most common error sources are connections with dimmers, transformers, and defective lamps.

Here are a few ways to prevent LEd bulbs from flickering:

Compatible Dimmer

LED lights are technically more complex than traditional light sources. This is particularly important when you want to dim the brightness. To do this, the LED bulb and dimmer must be properly matched.

Address The Voltage Changes Issue

This can be achieved during the wiring application. Since voltage change can happen due to the usage of many appliances at the same time and the sharing between your appliances and your LED light can make it flicker, make sure to check that the current running to your home or office is sufficient enough to power all your electronic appliances and lights to avoid flickering.

Fix Loose Wiring or Bulb

Flickering LED lights are usually due to loose connections and circuits. This would be the result of poor handiwork while attaching fixtures to the point of connection.If many lights flicker at the same time, then there could be a problem at the panel or the junction point that could be loose and requires re-tightening.

Defective Driver

An LED driver is a device that supplies power to one or more LEDs. It serves as a protective cushion as well as a system for managing electrical current.

If the driver is defective, flickering occurs. The only solution to this problem is to use better drivers. Constant drivers help in eliminating power current peaks thus eliminating the flickering problem.

Key Takeaways

To be precise, there can be many different reasons why LED  Lights flicker. Some of the most common reasons include voltage fluctuation, loose wiring, defective driver, and a dimmer that does not work properly.

Therefore, to fix the Flickering LED lights it is important to get the LED lights installed by someone who holds expertise in the field and can help you understand the functioning of the LED lights!
