Phase Dimming

Also known as mains dimming by leading (sometimes called Triac) or trailing edge. A trailing edge dimmer has a lower minimum load than leading-edge dimmers. This makes it a better choice for dimming modestly sized low-powered lighting circuits such as those used by LED, and include other benefits for the user such as smooth, silent dimming control, without any buzzing noise. Ecoled use mainly trailing edge dimmers. Phase dimming switches usually look like Push button type dimming using standard dimmer switches, although there are a number of more modern plates available. Using the best equipment you can dim down to around 5% using this type of dimming control.


1-10V dimming

Also known as Analogue dimming protocol which is one of the earliest and simplest electronic lighting control signalling systems. Simply put, the control signal is a DC voltage that varies between 1 & 10. The controlled lighting should scale its output so that at 10 V, the controlled light should be at 100% of its potential output, and at 1V it should at 10% output.

1-10V dimming requires 2 additional wires to run the signal along as well as the mains cable.


Stands for Digital Addressable Lighting Interface. The DALI protocol provides 256 levels of brightness between off and 100%, which is translated to a power level via a logarithmic dimming curve. This curve gives larger increments in brightness at high diming levels and smaller increments at low diming levels. Lighting scene control is a feature of this Dimming down to around 1% is possible using this type of dimming control, as well as lighting scene control.



Stands for Digital Multiplex and isa standard for digital communication networks that was originally intended as a standardised method for controlling light dimmers for stage lighting and effects.

DMX has also expanded to uses in non-theatrical interior and architectural lighting, being the primary method for linking controllers (such as a lighting console) to dimmers and intelligent lights.

Recently, wireless DMX adapters have become popular especially in architectural lighting installations where cable lengths can be prohibitively long.

DMX should allow you to dim almost to extinction.
