Battery-Powered Detection Light: Powered by 4 D-cell alkaline batteries (batteries not included), it can illuminate an area of 300 feet. The battery can provide up to 8 months of lighting. Energy-Saving Hallway Light: This light uses 80 bright and long-lasting SMD2835 LED lights. The 300-lumen lights can cover approximately 300 feet, and the frosted shades are designed to soften the light, causing no eye discomfort even at night. Motion Sensor Light: Thanks to the built-in PIR infrared motion sensor, when it detects motion up to 10 feet away in a dark environment, this LED ceiling light will instantly turn on. If no motion is detected after 20 seconds, it will automatically turn off to save power. Two Modes Available: There is a switch near the motion sensor to turn the light on/off. When the switch is on, the lights will remain off during the day and only turn on at night. When the switch is off, the lights can be activated throughout the day. Easy Installation & Wide Application: No wiring is required, and it can be installed quickly and easily in under 10 minutes. Wireless LED ceiling lights are ideal for illuminating closets, kitchens, stairwells, laundry rooms, yards, and sheds.
