How to make the default template to completely dark?

I adjust the angle of the sourcelight to midnight ,and turn off all lights in the scene,but it’s not completely dark,how to do?

really!Thanks a lot . Even when i put the directionlight、skysphere、skylight、atmosphericfog in the empty level ,it’s also different between the default level and the empty level.But the cloud in the empty level with skysphere looks not good as the default level,and there is always a big ugly white light spot in the central sky,could you like to tell me why all these happened? what i really want is a real and beauty sky and sunlight

Open up the template level, rotate the sun and build lighting, this should change time of day. There’s also world settings that contain other options for lighting to get it to become darker.

Thanks a lot ,but what i need is completely dark,like the real world

did you find any awser for this danny?
