Hager EEN003 External Light Sensor for Twilight Switch, Surface-Mounted, IP55, 1.5 m Cable, Grey

Outdoor lighting often stays on too long or switches too early when no reliable ambient light detection exists. The Hager EEN003 external light sensor solves this by measuring natural light levels and sending the signal to a compatible twilight switch, ensuring lights activate only when darkness actually falls.
