Auto uses the built in pir (passive infra red) sensor to activate the light if it detects movement.
The bracket is well designed and the light is easy to snap into it. And mounting hardware is good. Comes with screws and anchors that are used to install the base plate. But it's not very heavy, so i ended up only using 2 with anchors.
Only drawback is that it requires 6 aa batteries. Works great, takes 6 aaa batteries. The only downfall is, it takes 6aa batteries in each light.
It is a two-car garage and it is very dull lighting. It is considerably dimmer. Advertised as a 2 pack. The motion detector is terrible.
Glass shades are thick and very heavy for a lamp. These screws show in the side of the base on the ceiling.
