Motion Sensor Light: Built-in PIR infrared motion sensor detects motion up to 18 feet away in low-light conditions, automatically turning the LED ceiling light on. The light turns off after 20 seconds when no motion is detected, helping conserve power.Two Operation Modes: A switch located near the motion sensor controls the light-sensitive (photocell) function. When enabled, the light operates only at night and remains off during daylight. When disabled, the light can activate regardless of ambient light levels.Battery-Powered Design: Requires 4 D-cell alkaline batteries (not included). Illuminates areas up to 300 square feet. With average usage of 20 activations per day, batteries can last up to 6 months.Bright LED Illumination: Equipped with 118 SMD2835 LEDs, delivering up to 300 lumens of brightness. Provides wide, even light distribution to help prevent trips or falls in dark areas, ideal for ensuring safety at night.Easy Installation & Wide Use: No wiring required. Installs in minutes. Suitable for indoor and outdoor use in bedrooms, bathrooms, hallways, stairways, basements, closets, workshops, entryways, and driveways. Helps reduce the need to leave lights on constantly.
