Many people have seen flickering light bulbs at home or in the office. If it is an old fluorescent tube or incandescent bulb, the problem is usually in the ballast or filament. In such cases, changing the bulb will solve the problem.

But LED lights are different. If they flicker, there can be multiple reasons for this. Let’s understand why LED bulbs flicker and how to fix it.

Why do LED lights flicker?

The most common reason is that LED bulbs can flicker when the power supply frequency drops below 50 Hz. Other causes include loose wiring, faulty dimmer switches, or faulty LED components such as drivers. Below are some of the causes in detail:

Bad LED drivers

LED drivers regulate current and protect the light. If the driver is faulty, the LED can flicker due to heat or power instability.

Loose connections

If the wiring is not tight or the bulb is not properly fixed, it can cause flickering. If a lot of lights are flickering together, there may be a problem with the main power panel.

Faulty dimmer switches

Standard dimmer switches do not cut power properly to LED lights. This causes them to flicker.

Low-quality bulbs

Cheap LED bulbs often flicker. Good quality LEDs cost more, but they last longer and work better.

Power surges

If high-power appliances such as heaters or microwaves are used on the same circuit, it can cause LED lights to flicker.

How to fix LED flickering?

Check the installation

Make sure all wires are connected properly.

Secure the bulb in its holder properly

Check the power supply and connections.

Turn off the power and fix loose wiring.

Avoid voltage fluctuations

Using too many electrical devices at the same time can cause voltage fluctuations, which can cause flickering. Try to use only a few devices at a time.

Find the faulty part

If the LED light is still under warranty, contact the manufacturer for a replacement. Otherwise, call an electrician to check the wiring and switches.

Use high-quality LED bulbs

If flickering continues, replace old bulbs with better-quality LED bulbs. Modern LED bulbs last longer than older models and work better.

Choose good LED drivers

Cheap LED drivers cannot handle power surges properly. A good-quality driver stabilizes the power and reduces flickering.

Contact the manufacturer

If nothing works, contact the LED bulb manufacturer. If your bulb is under warranty, they will repair or replace it.

Buy from a trusted lighting company

To avoid such problems in the future, buy LED lights from a trusted brand that provides good quality lighting solutions.

By following these steps, you can stop LED flickering and ensure better and more consistent lighting at home or at work.
