Automatic lighting

Automatic lighting when it gets dark is very convenient. For example, street lighting in cities uses it to provide citizens with light during dark hours of the day. It can also be used indoors for places that always should have light available. Whether it is night, rainy day (or sudden solar eclipse (: ) this circuit will provide artificial light when needed.
