Two Operating Modes: The ceiling light features two selectable modes, Auto and ON. In ON mode, the light remains on continuously. In Auto mode, the motion sensor activates the light only when movement is detected, helping manage power usage when the light is not needed. Battery Powered LED Lighting: This motion sensor ceiling light operates on six AA batteries per unit (not included). It provides 6000K cool white illumination with up to 400 lumens, using an array of LED lights and a frosted cover designed to diffuse light evenly. Compact Size for Multiple Areas: With a slim profile measuring approximately 7.2 inches in diameter and 1.8 inches in height, the flush mount light is suitable for various indoor spaces such as closets, hallways, stairways, storage areas, basements, laundry rooms, and bathrooms.
