It’s an automatic system, completely integrated in the light fixtures that does not require any additional wiring or external hardware.
It reduces the luminous flux according to a pre-set program (up to 5 dimming and time steps), adjustable like the picture shown in the left page.
For three days after the installation, the lights will work at full power, reading the on/off time, starting to reduce the luminous flux from the fourth day.
The operation is based on calculating a virtual midnight (average on-off moment) used as reference to apply the pre-set program.
The calculation of the virtual midnight is automatic and keeps updating during the year, adjusting to the daylight hours. The system is mostly used for parking lot lighting and streetlighting.
