They come with hook and chains for an exposed rafter install and screws for a flush to dry wall ceiling. Daisy chaining really helps to plug in up to 4 lights from 1 outlet. They daisy link together with is a really nice feature.

The brightness level is comfortable and they can be directed off-center. Brightens up cellar nicely.

The motion sensor works amazing. The sensor works for the distance i have which is about 3 feet from the nearest door. No problems with the motion detector.

Lights come on instantly when you walk in or ride your motorcycle in. Perfect for our garage with no lights other than our garage door opener.

Motion sensor is atrocious. Even swinging the light itself isn't sufficient. The light is almost useless if you intend to use it in an area where people may be stationary for more than a few minutes.
