My neighbor was so nice and had recorded daily when my simulator is tackled. This difference was daily for up to 60 minutes. This of course is great because an "observer / burglar" yes otherwise might suspect a timer. Thus, the light sensor is serving.
There are 3 modes: continuous lighting, 4h lighting at night (probably for the summer) and 8h lighting at night (probably for the winter). Power consumption is due to the LED - low lighting VERY.
The only complaint: I compared the illumination from the simulator to the real TV. The simulator has a lot more "lightning effects", almost as if you permanently similar an action movie looks. But otherwise the simulation is already very good.
I am satisfied and would buy the simulator again.
