Review on Otinlai Silver 20 LED Under Cabinet Lights - Motion Sensor, Night Light, LED Battery Lights, Stick Anywhere, USB Rechargeable, Magnetic LED Light Bar by Chad Fox

It has a 360 degree sensor so any movement near it will turn on the light. I put black tape on the sensor so it only works if I put my hand underneath. One charge with the adapter lasts about 2 months before the light fades, so it lasts a long time. If there is one dark shelf that drives you crazy, then this is for you. It's best to have an outlet within 3 feet of the light so you don't have to remove it. There are magnets on the back, so you need a piece of metal where you want to stick it.
