DALI (Digital Addressable Lighting Interface) is generally used to provide area lighting control over a number of lighting circuits. It relies on an additional two-core cable connection between the dimmer control and the LED driver. It’s worth noting that there is a growing number of Dali-based dimming options for the domestic market. The LED driver is linked to a push-button controller (a retractive switch) at the wall, using a two-core cable. As there’s nothing clever in the control beyond a spring-loaded connector, there can be no problem with component compatibility; it’s all going on inside the driver. But it’s always wise to confirm the ability of the driver to provide those low lighting levels before committing to a specification.
