A trailing edge LED dimmer switch controls the brightness of lighting by cutting off the voltage in the latter half of each AC waveform. It offers quieter, smoother dimming, better LED compatibility, and longer bulb life compared to leading edge dimmers, making it a perfect choice for modern LED lighting setups.
How Does a Trailing Edge LED Dimmer Switch Differ from a Leading Edge Dimmer?
Trailing edge dimmers work by cutting off the trailing half of the AC waveform. This provides a softer start, quieter operation, and smoother dimming. In contrast, leading edge dimmers cut off the leading half, making them ideal for incandescent or halogen bulbs but less compatible with LEDs. Trailing edge dimmers offer quieter operation and better performance for LED lighting, reducing buzzing and flickering.
What Types of LED Bulbs and Lighting Are Compatible with Trailing Edge Dimmer Switches?
Trailing edge dimmers are compatible with most dimmable LED bulbs, including retrofit LED downlights, incandescent bulbs, and halogen lamps. However, they do not support CFLs or fluorescent lighting and are unsuitable for non-dimmable LEDs or smart bulbs.
Compatibility Advice: When choosing a trailing edge LED dimmer, ensure the LED bulbs are labeled as dimmable. Some advanced dimmers, such as those from Repenic, offer extended compatibility, ensuring smooth dimming and longevity for your LEDs.

What is a trailing edge LED dimmer switch?
A trailing edge LED dimmer switch adjusts brightness by cutting the end of each AC waveform. It provides smooth, silent dimming ideal for modern LEDs, preventing flickering and voltage spikes, and extending bulb life. These dimmers use advanced electronics to ensure compatibility with LED drivers and reduce stress on sensitive components.
How does a trailing edge dimmer work?
Trailing edge dimmers operate by letting the beginning of the AC cycle flow normally and then gradually cutting off the latter half of the waveform. This phase-cutting method delivers a controlled voltage to the bulb, resulting in smooth dimming, minimal electrical noise, and improved compatibility with LED electronics.
What are the benefits of using a trailing edge dimmer with LEDs?
Trailing edge dimmers offer silent operation, prevent flickering, and ensure better compatibility with LED drivers.
