Reference code:

Which type of dimmer is it?

DALI - A lighting management control system.

Analogue dimming, this is usually referred to as 1-10v dimming.

AC mains/TRIAC

AC/TRIAC dimmers are designed for resistive loads such as incandescent or halogen lights. These phase controlled dimmers are not compatible with LEDs since LEDs do not appear as a resistive load.

What kind of dimmer is being used?

Reference code:

Please note, a converter is required if an analogue dimmer is being used.
