This LED motion sensor light features 2 usage modes, constant-on and motion-sensing, meeting diverse lighting needs. In constant-on mode, it supports 2 dimming methods: you can choose fixed brightness levels (10%/50%/100%) or achieve stepless dimming via the +/- buttons. It also comes with a 4-level timer function (10/30/60/120 minutes), flexibly adapting to different usage duration requirements.The motion-sensing mode has 2 settings: night mode and day mode. It can detect human activity within a 10 ft./120° range and automatically turns off after about 20 seconds of no detection, ensuring high energy efficiency.Equipped with a built-in 1000mAh rechargeable battery, the product can be charged via the included USB cable. When fully charged (indicated by a blue light), it can be used for 10-20 days in motion-sensing mode, eliminating the need for frequent replacement of disposable batteries.Installation is convenient and versatile: the built-in strong magnet allows direct adsorption to iron surfaces, or it can be attached to any flat surface with 3M adhesive, no screws or drilling required. The square magnet design ensures more stable adsorption.
