The Astroflash is a twilight switch that allows you to control any electrical application to be switched ON or OFF according to an ambient light threshold, which you can adjust.

Examples of applications:

  Switch ON light(s) at night (for display windows, public lighting, advertising sign boards etc...)

  Close down shutters at night

  Open down blinds at sunshine

  Any other applications depending on light level between 5 to 2000 lux.

This product correctly installed and adjusted will help you to save energy and labour paying back quickly for the investment you or your customer have made.

In many applications (for example lighting at night) where the light is not required the full night it is strongly advisable to install a combined time-switch together with this device to switch OFF the light if it is not required the full night: this will provide extra savings.
