Anker Eufy Lumi (LED Sensor Light) [Installable Anywhere / Motion Sensor Equipped / Set of 3] Operates on 3 AAA batteries. One unit has been used, but two are unused. The used unit was attached to a hallway wall with the included double-sided tape, so the adhesive strength may be weakened. I was using them for pathways in the hallway at night. The light is just right, not too bright, and not dazzling, making it ideal for pathways to the toilet. - Brand: eufy - Type: Motion Sensor Light - Feature: Slide-open - Quantity: Set of 3 - Color: White
