Why LED Lights Flicker When Connected to a Standard Dimmer Instead of an LED Dimmer
As a homeowner or DIY enthusiast, you may have noticed your LED lights flickering when connected to a standard dimmer switch. This flickering happens because traditional dimmers are designed to work with incandescent bulbs, not energy-efficient LEDs. Let’s dive into why this happens, how to fix it, and what you should consider when upgrading your dimmer switch.

Understanding the Flicker
LED lights are different from incandescent or halogen bulbs. They use a low voltage power supply to operate, whereas traditional dimmers work by reducing the voltage to dim the light. The mismatch between the dimmer and the LED’s low voltage driver often results in flickering or an inconsistent light output.
Why LED-Specific Dimmers are Essential
LED dimmer switches are designed to handle the low wattage of LED bulbs more efficiently, providing smoother and flicker-free dimming. Standard dimmers cannot do this, leading to compatibility issues.
LED dimmers like the V-PRO LED Dimmer Module and the LEDIT-B100 Hamilton LED Dimmer Module are specifically made to work with LED lighting and help eliminate these problems. These dimmers provide:
- Smooth Dimming: LED dimmers offer smoother transitions and eliminate flickering by adjusting to the low voltage requirements of LEDs.
- Energy Efficiency: LED-compatible dimmers help maximize the energy-saving benefits of LED lights.
Popular LED Dimmer Modules Available at Electrical4Less
You can find these highly reliable and popular dimmer modules at your local Fulham electrical trade counter, Electrical4Less:
- V-PRO LED Dimmer Module: Offers leading-edge, trailing-edge, or hybrid dimming control, making it flexible for various LED setups. It has soft-start technology to protect bulbs and extends their lifespan. This dimmer can handle up to 10 LED lamps per circuit depending on wattage.
- LEDIT-B100 Hamilton LED Dimmer Module: Specifically designed for smooth, flicker-free dimming of LEDs. This high-performance trailing-edge dimmer is perfect for use with low-wattage LED setups.
Always ensure that the total number of LED lamps or the total wattage complies with the dimmer’s specifications. For example, while these modules are great for handling multiple LED lights, exceeding the maximum wattage or lamp count can cause issues. If you are ever unsure, it’s best to contact a qualified electrician.
