Meet the Silk by Saffron: a smart light bulb that automatically adjust its color temperature throughout the day to provide you with the right kind of light tailored to your circadian rhythm. The Silk Light does not interfere with your sleep like other artificial light sources. You can control your light using the nClick switch.
The Silk light is compatible with iOS and Android devices. It is easy to set up too. Just connect the bridge, enter your WiFi credentials, and you are set. You can find out more about it on Kickstarter.
