LED lights are more complicated to dim than incandescent and halogen light bulbs.
Many people have encountered flickering or other disturbances from poor-quality LED lights or incompatible dimmer switches.
It's for these reasons that we only sell:
1) High-quality dimmable LED lights from reputable brands.
Brands such as Philips and Osram have invested a lot into ensuring their dimmable lights work with the broadest possible range of dimmer switches.
2) Specifically optimised LED dimmer switches.
In addition to careful brand and product selection, we test all the products we sell. This includes testing our dimmable LED lights on the above-mentioned LED dimmers.
What is a Trailing Edge Dimmer or Leading Edge Dimmer?
Most mainstream dimmer switches employ phase-cutting technology to achieve dimming. They work by cutting off part of the mains voltage waveform to vary the average (or 'RMS') voltage fed to the lamp. The brightness of the light can therefore be controlled by increasing or decreasing the voltage.
There are two ways to modify the mains voltage: at the beginning or end of the sine wave. A dimmer where the 'cutting off' is done at the start is called a leading edge dimmer. And a dimmer where the 'cutting off' is done towards the end of the sine wave is called a trailing edge dimmer.
What is a Universal Dimmer Switch?
A universal dimmer is designed to work with all main types of lighting, including LED. In that sense, our Diginet dimmers can be called universal dimmers. Here is a summary table of compatible lighting load types for the MEDM, MMDM/RT, and MMDM/PB LED dimmers:
|Lighting Load Type
|Maximum Load (Wattage)
|Dimmable LED Lights / Drivers
|Incandescent / 240V Halogen
|Dimmable Compact Fluorescent Lamps (CFLs)
*For example, those used by 12V MR16 LED lights.
What is Two-Way, Three-Way or Multi-Way Dimming?
Two-way dimming describes the ability to turn a lighting circuit on/off and dim up/down from two switches in a room. Similarly, three-way dimming is the same concept from three spots.

With our Diginet dimmer MultiMate technology, you can achieve multi-way dimming without needing extra wring. You have complete control over your lights from any dimmer connected to the lights in a particular room.
Most old-fashioned dimmers do not function well together on the same circuit and are, therefore, not capable of multi-way dimming.
