The visual impact of outdoor is good. The unit has 3 settings continuous operation, twilight switch with 4 hours and twilight switch with 8 hours. The twilight switch is controlled by a light sensor. In our case, it was so bright that the light sensor responded by Fake TV in the room at the light and abschaltete again - after a few minutes in the dark, he started again and then off again by its own light, etc ... I have the device then set to continuous operation and preceded by a simple switch, it runs fine.
