Really Simple Design this- One device is the SOlar Panel and can be mounted beside or up to 5 feet away from the LED floodlight via the discrete connector cable for better light, and the floodlight itself has rechargeable cells in. Although it's not as bright as the wired-in electrical LED floodlights I've used the output is still pretty decent and the PIR sensor built in means it activates the light onyl when it detects body movement in the vicinity
Both devices come with a mounting plate ans screws/wallplugs
