A Digital Addressable Lighting Interface (DALI) receives power from a high voltage power circuit when in a standby mode. The DALI remains in a standby mode until signal activity on a DALI bus is detected, or the DALI may periodically switch from the standby mode to an active mode so as to sample any activity on the DALI bus. If no activity is detected then the DALI returns to the standby mode. If DALI bus activity is detected then the DALI remains in the active mode. The DALI receives power from a power controller when in the active mode. The DALI remains in the active mode so long as the power controller is supplying power to an electrical device.
