1. Product Overview
The ROMECH Under Cabinet Light is a versatile, wireless lighting solution designed for various indoor spaces. Each light bar features 130 LED beads, offering three adjustable color temperatures (3000K warm, 4000K natural, 6000K white) and stepless dimming to suit different lighting needs. Equipped with a smart motion sensor, the light automatically activates in dark environments upon detecting human movement within a 10ft/120° range and turns off after 20 seconds of no motion. Its ultra-thin design and durable aluminum alloy construction ensure both aesthetic appeal and longevity. A built-in 3000mAh rechargeable battery provides extended operation, easily charged via USB-C.

5.3 Motion Sensor Functionality
In Motion Sensor mode, the light detects human movement within a 10-foot (3-meter) range and a 120° angle. It is designed to conserve energy by only activating in dark or low-light conditions. If the ambient light is sufficient, the motion sensor will not trigger the light.
