Twilight Switch ORNO OR-CR-227 with Light Sensor 10A 230V Adjustable 5–50 lx

ORNO OR-CR-227 is a twilight (dusk) switch with an integrated light sensor that automatically controls lighting according to ambient illumination. Rated for 10 A at 230 V, the device provides adjustable sensitivity from 5 to 50 lux, allowing precise setting of the turn-on/turn-off threshold. The compact design fits typical indoor or outdoor installations where automatic switching of lighting circuits is required for energy efficiency and convenience.

Advantages

The twilight switch offers adjustable sensitivity between 5 and 50 lx for accurate activation at desired light levels and reduces manual intervention by automating lighting control. With a 10 A switching capacity at 230 V it is suitable for many common lighting loads, and the integrated light sensor removes the need for separate photocell wiring. The unit is designed for straightforward installation and stable operation in applications where automatic dusk-to-dawn switching is needed.

Suitable for

• Garden and pathway lighting
• Outdoor security lights and floodlights
• Porch, balcony and entrance lighting
• Corridor and stairwell lighting in residential buildings
• Energy-saving automatic control of indoor lighting circuits

Key specifications

• Operating voltage: 230 V AC
• Maximum switching current: 10 A
• Adjustable light sensitivity range: 5–50 lux
• Built-in ambient light sensor (photocell)
• Designed for automatic dusk-to-dawn switching

How to use

Install the twilight switch according to local electrical regulations and wiring standards, ensuring power is disconnected before making connections. Mount the unit where the light sensor can accurately measure ambient illumination and is not directly exposed to targeted lighting from the controlled fixture. Adjust the sensitivity dial to set the desired threshold between 5 and 50 lx; lower values cause the switch to activate at darker conditions, higher values at brighter conditions. After wiring and adjustment, restore power and verify correct operation by observing switching behavior at varying ambient light levels.

Usage recommendations

For reliable performance, avoid mounting the sensor where it faces direct illumination from the controlled light or from nearby fixtures. Choose a location sheltered from heavy weather if the installation is outdoors, and verify that the connected load does not exceed the 10 A rating. Regularly check sensor location and cleanliness to maintain accurate light detection.
