What kind of dimmer is needed for LED lights?

Answered by Stephen Mosley

When it comes to dimming LED lights, it is important to choose the right type of dimmer to ensure optimal performance and compatibility. The two main types of dimmers commonly used are trailing edge dimmers and leading-edge dimmers.

Trailing edge dimmers are generally considered to be the more suitable option for dimming LED lights. These dimmers are designed to work specifically with electronic low-voltage transformers, which are commonly used in LED lighting systems. Trailing edge dimmers work by cutting off the trailing edge of the AC waveform, resulting in a smoother and more precise dimming experience. This helps to minimize flickering or buzzing that can sometimes occur when dimming LED lights.

On the other hand, leading-edge dimmers are typically better suited for traditional incandescent and halogen light bulbs. These dimmers work by cutting off the leading edge of the AC waveform, which may not be as compatible with the electronic drivers used in LED lights. Using a leading-edge dimmer with LED lights can result in reduced dimming range, flickering, or even damage to the LED bulbs.

It is worth noting that not all LED lights are dimmable, so it is important to check the packaging or specifications of the LED bulbs or fixtures you are using to ensure compatibility with dimmers. If the LED lights are dimmable, it is recommended to use a trailing edge dimmer for the best performance.

Personal experience-wise, I recently upgraded the lighting in my living room to LED bulbs and wanted to be able to dim them for different settings and moods. After doing some research and consulting with an electrician, I learned that trailing edge dimmers were the best choice for LED lights. I installed a trailing edge dimmer switch and was pleased with the smooth and flicker-free dimming I was able to achieve with my LED bulbs.

When it comes to dimming LED lights, it is important to choose the right type of dimmer for optimal performance. Trailing edge dimmers are generally recommended for LED lights, as they are specifically designed to work with electronic low-voltage transformers commonly used in LED lighting systems. Leading-edge dimmers, on the other hand, are better suited for traditional incandescent and halogen light bulbs. Always check the compatibility of your LED bulbs with dimmers and consider using trailing edge dimmers for the best dimming experience.
