I’ve had these Brilliant Evolution - Wireless LED Motion Sensor Lights installed for a couple of weeks and I absolutely love them. Two of them are under the top hanging cabinets in my kitchen and the other one is under a shelf in my bathroom above my toilet. These lights take 3 triple A batteries. They have sticky tape on the back of them for easy installation. They are motion lights. They stay on until no more motion is detected and then they shut back off. The lights look great and the light has the right amount of brightness. I would definitely get these lights again.
