What is Trailing Edge Dimmer?

A trailing-edge dimmer is a type of dimmer switch used to control the brightness of lights, particularly those with electronic or LED bulbs. Unlike leading-edge dimmers, which cut the voltage supply at the beginning of each alternating current (AC) cycle, trailing-edge dimmers cut the voltage at the end of each cycle.

Trailing-edge dimmers are generally considered more suitable for use with electronic and LED lights because they provide smoother dimming and reduce the risk of flickering or buzzing. They also tend to generate less electromagnetic interference (EMI) compared to leading-edge dimmers, making them a popular choice for modern lighting systems.

What are the benefits of the Trailing Edge Dimmers?

1. Compatible with LED and Electronic Lighting products.
   Smooth and flicker free dimming, ensuring performance and provide longevity.

2. Reduced electromagnetic interference (EMI)

• Compatible with LED and Electronic Lighting products.
  Smooth and flicker free dimming, ensuring performance and provide longevity.
  
• Reduced electromagnetic interference (EMI) produce less interference when compared to leading-edge dimmers. More reliable electrical environment.
  
• Extend lifespan for bulbs
  Trailing-edge dimmers can help prolong lifespan of bulbs especially LED bulbs. Lowering the intensity of light reduces heat generation within the bulb, which can help prevent overheating and premature failure, ultimately increasing the longevity of the bulbs.
  
• Quiet Operation compared to edge dimmers. Noise levels are kept to minimum, a great plus to get a trailing edge dimmer.
  
• Precision and Control, regulation of the electrical flow to dimmable light fixtures by cutting off the voltage supply towards the end of each AC cycle, enabling precise control over the brightness of the lights.
  
• More compatible with general lighting products compared to TRIAC Dimmer.

Points to note about Trailing Edge Dimmers

Trailing-edge dimmers remain a popular choice for dimming LED and electronic lighting systems due to their compatibility, energy efficiency, and smooth dimming capabilities. Proper selection, installation, and compatibility testing

Please make sure your lighting product is dimmable before buying and installing.

What is the difference between Trailing Edge and Leading Edge Dimmers?

Trailing-edge dimmers control the flow of electrical current to dimmable light fixtures, typically LED or electronic lighting systems. Unlike leading-edge dimmers, which cut the voltage at the beginning of each alternating current (AC) cycle, trailing-edge dimmers cut the voltage at the end of each cycle.
In ELI5 terms, Trailing Edge – smoother and flow, more costly vs Leading Edge – stagger, step, cheaper
