Dimming curves for DALI devices vary, with some reaching a maximum of 78% dimming at full output. Generally, a DALI dimming curve is a graph that shows the variation of the light output of a DALI-enabled device as it is dimmed. The graph typically shows the relationship between the dimming level (0-100%) and the relative light output (0-100%). The graph also includes the minimum dim level, which is the lowest dimming level at which the device will still be able to maintain a consistent light output.
The shape of the dimming curve also varies from device to device, with some reaching a maximum dim level of 78% at full output and others having a dimming curve that can reach as low as 10%.
