Quattro dimming allows you to regulate the light level without a regular dimmer. The dimming function is integrated into the driver. This eliminates the need for a dimmer, as well as any coordination issues between the dimmer and the fixture. It functions as follows:

• toggle the switch on, will lead to a light output of 100 %
• a second toggle will set the light output to 50%
• a third toggle, to 25%

A regular off-toggle will switch the fixture off
