I am so glad that I got this 3 pack of LED Motion Sensor Lights from Brilliant Evolution! I had been looking for a better light to use in our bathroom so when anyone has to get up to use the bathroom at night they don't have to turn on a bright light while they are up. These are easy to use! They are battery operated and take 3 AA batteries. You can either hang them up by using the stickies provided or screws that are provided. They give off great light (60 lumens) but not too bright where it hurts your eyes. I love that they are motion activated and will come on automatically when your 10 feet away or closer. The lights shut off after 30 seconds if no motion is detected which saves battery. I have put one in the bathroom and a couple in a stairway that leads up to apartments above our garage. These are great and so helpful!
