Why Are My LED Lights Flickering?

Installing LED Retrofit Bulb into Ceiling Fixture

Flickering LED lights can be more than just a nuisance; they can indicate underlying issues in your electrical system that may need attention. Chesapeake Electric is here to guide you through the common causes of flickering LEDs and provide solutions to ensure your lighting remains stable and reliable. Here’s what you need to know if you’re asking yourself, “Why are my LED lights flickering?”

Loose Connections

One of the most common reasons for flickering LED lights is loose connections. If the connections between your light fixtures and the power source aren’t secure, it can cause intermittent contact that leads to flickering. This can occur at any point in the circuit, from the wiring in your wall to the connections in your light fixture or the lamp’s socket.

Voltage Fluctuations

LEDs are particularly sensitive to changes in the voltage that powers them. If the voltage in your home is not stable, it can lead to flickering lights. Voltage fluctuations can happen due to various reasons, such as heavy appliances pulling large currents on the same circuit, or issues with your utility service.

Incompatible Dimmer Switches

Using a dimmer switch that isn’t compatible with LED bulbs can cause flickering. Many older dimmer switches are designed for higher electrical loads of incandescent bulbs and do not work well with the lower voltage requirements of LEDs. Switching to a dimmer designed specifically for LED bulbs can resolve this flickering issue.

Poor Quality LED Bulbs

Not all LED bulbs are created equal. Lower quality LEDs or those not designed to meet certain standards might flicker due to poor construction, inadequate heat management, or substandard materials. Investing in high-quality, reputable brands can prevent flickering issues and offer better longevity and performance.

Faulty Drivers

LED drivers convert your home’s higher voltage AC power into the lower voltage DC power that LEDs require. If these drivers are faulty or deteriorate over time, they can cause your LEDs to flicker. Replacing a faulty driver is often a simple solution that restores stability to your lighting.

Electrical Grid Issues

Sometimes, the problem extends beyond your home’s wiring. Issues in the electrical grid, such as grid switching by your energy provider, can also lead to transient voltage fluctuations that cause your lights to flicker. Although this is less common, it’s worth considering if you’ve ruled out home-based causes.

Diagnosing and Fixing the Issue

To diagnose the exact cause of flickering LED lights, a thorough inspection by a professional electrician is often necessary. Chesapeake Electric can help identify whether the issue is with the bulbs, fixtures, wiring, or something external. Our skilled technicians can provide quick fixes like tightening connections or replacing components, and more comprehensive solutions like upgrading your electrical panel or wiring to accommodate modern lighting needs.
