What is Leading Edge Dimmer

A leading edge dimmer, also known as a TRIAC dimmer, is a type of dimming technique commonly used in the lighting industry. It is designed to adjust the brightness of a light source by controlling the amount of current flowing through it. This dimming technique involves cutting off the current as the AC waveform begins, right after it crosses zero. By doing so, it creates a rush of voltage and current to the light source, allowing for adjustable brightness.

Leading edge dimmers are typically used with incandescent bulbs and are suitable for 230V halogen bulbs as well. However, they may also be compatible with some LED bulbs, although this information should be specified on the dimmer switch or its packaging. It is important to note that leading edge dimmers have a limited dimming capability range, usually around 40%. This means that the light output can be adjusted, but it may not be possible to completely dim the light source.

Frequently Asked Questions

What Is the Difference Between LED Dimmer and Normal Dimmer

As LEDs have a significantly lower wattage compared to incandescent bulbs, trailing edge dimmers offer a more compatible wattage range, ensuring optimal performance and longevity for dimmable LED lights.

How Many LED Lights Can Be on One Dimmer Switch

Varilight suggests that it is best to have a maximum of 10 LED lamps connected to one dimmer module. However, if you have a three gang dimmer plate, you can have a total of thirty LED lamps on the plate, with ten lamps connected to each module.

What Happens if You Use a Dimmer Switch for LED Lights

Once you install a dimmer switch specifically designed for LED lights, you will enhance your lighting experience. This modern dimmer switch is designed to efficiently control the electricity flow to the LED bulbs, allowing you to easily adjust the brightness levels and create the desired ambiance in your space.

Do Dimmers Require Different Wiring

If you are replacing an old single-pole light switch with a dimmer, the wiring remains the same with the same connections. Similarly, a regular 3-way switch can be easily replaced with a 3-way dimmer. The dimmer component is integrated into the switch and does not necessitate any extra wiring.
