It is an intelligent twist-lock photocontrol that supports DALI dimming and constant illumination control, equipped with a dedicated midnight night mode for intelligent street and outdoor lighting.
The twist lock design enables fast installation, stable electrical connection, good waterproof and anti-loosening performance, making it widely suitable for standard street light and garden light sockets.
It detects ambient brightness in real time via the photosensitive probe and automatically adjusts output brightness through DALI protocol to maintain stable and consistent illumination on the ground.
Midnight night mode automatically dims the lights to a lower brightness level during late night hours, which greatly reduces energy consumption while maintaining basic road safety and lighting demand.
It is mainly used in street lighting, road lamps, garden lighting, community lighting and other outdoor public lighting that requires intelligent dimming and energy-saving operation.
