Thanks to the use of two wide-angle light-sensing elements, the controller is better able to detect levels of darkness.

**What is the twilightSwitch controller used for?**
The twilightSwitch controller is a darkness (twilight) sensor for 12–24V DC LED strips. The lighting switches on with a gradual fade-in (approximately 2 seconds) once ‘darkness’ is detected.

 Thanks to the use of two wide-angle light-sensitive elements, the controller is better able to recognise levels of darkness.

**How does switching on, switching off and control work?**
The lighting switches on automatically with a gradual fade-in (approx. 2 seconds) when ‘darkness’ (< 1 lx) is detected.
The lights switch off automatically with a gradual dimming (approx. 2 seconds) once ‘light’ is detected (< 1 lx).

**How do I power the twilightSwitch, and what is the maximum load?**
The maximum load is 5A at 12–24V DC, which corresponds to 60–120W. It is powered from the same source as the LED strip.

**Is the twilightSwitch suitable for aluminium profiles with a diffuser?**
Yes! The twilightSwitch controller can be concealed within LED profiles fitted with a diffuser. The driver has minimal self-light leakage; however, it is recommended to position it away from (protect it against) excessive exposure to its own light.

**The twilightSwitch controller does not have Wi-Fi.**
There is no alternative to the add-on Wi-Fi module – none of the BleBox controllers can read such a signal.
If you are looking for a sunrise/sunset sensor in BleBox Wi-Fi controllers, almost all of them feature a schedule with an astronomical clock.
