Automatic Motion Sensor Lights for Your Smart Life. Yurnero wireless LED ceiling light provides a new way to light up stairways, hallways, laundry rooms, basements, and more. It features Smart Dual Light Modes with Auto-Sensing, allowing you to switch between Daylight Mode (24/7 motion-activated lighting) and Night Mode (auto-activates at dusk and turns off after 20 seconds). This is ideal for energy savings and tailored illumination based on ambient light levels. The light offers Precision Motion Detection & Wide Coverage with a 120° wide-angle PIR sensor that detects movement up to 6 metres (20ft), covering 28m² (300sqft). It instantly brightens dim spaces like stairwells or closets, even when your hands are full. Experience Eye-Comfort Technology & Powerful Output with 400-lumen natural white light (6000K) from 80 long-life LEDs, softened by a frosted cover, providing gentle yet bright illumination for safe navigation in dark areas. Enjoy 6-Month Battery Life & Hassle-Free Use, as it runs on 4xD-cell batteries (not included) and lasts over 180 days with typical usage. The light features a removable blue protective film for a pristine finish and maintenance-free LEDs rated for 50,000+ hours. Install wirelessly in 5 minutes with no wiring needed. Choose between peel-and-stick mounting or screw-fix options, making it perfect for rentals, listed buildings, or spaces lacking wiring such as closets, attics, garages, pantries, and hallways.
