Leading-Edge vs. Trailing-Edge Dimmers: Which Is Best for Your Lighting?
Share
The main difference between leading-edge and trailing-edge dimmers is how they control power to the light and their compatibility with different bulbs:
Leading-Edge Dimmers:
- How They Work: Cut power at the start of the AC wave.
- Best For: Incandescent and halogen bulbs.
- Performance: Can cause flickering or buzzing with LEDs; less smooth dimming.
- Cost: Cheaper and uses older technology.
Trailing-Edge Dimmers:
- How They Work: Cut power at the end of the AC wave.
- Best For: Modern LEDs, some halogens, and CFLs.
- Performance: Flicker-free, smoother dimming.
- Cost: More expensive but better for LEDs.
In Short:
Use leading-edge for older bulbs and trailing-edge for modern LED lighting for better performance and reliability.
Key Differences
| Feature | Leading Edge | Trailing Edge |
|---|---|---|
| Voltage Cut-Off | At the start of the sine wave | At the end of the sine wave |
| Best For | Incandescent, halogen bulbs | LEDs, some CFLs, halogens |
| Performance | Can cause flickering/buzzing | Smooth, flicker-free dimming |
| Cost | Lower | Higher |
| Technology | Older (triac-based) |
Newer (MOSFET/IGBT-based) |
