Mini photo sensor switch???

[yobresal]

Hi there, I am looking for a mini photo sensor switch so that I can use it for an outside light. Something that will activate the light once the sun goes down. Does anyone know if there is such a thing? Maybe the size of a box of tic tacs or smaller. Any help would be appreciated. Thanks.

2)

3) Something like this can be modified...

4) or you can build one. There are a ton of circuit on the net...

This works. The biggest part is the relay. You can change the sensitivity by changing the value or the resistor (in the bottom left).
