In comparison with the previous one, this neck light narrowed the width of the neck area to fit your neck more comfortably and get more steady, extended the length of the 2 flexible arms for easier operation and to hold the position more stable, and reduced the weight to reduce your fatigue after a long time reading and knitting. Perfect for book lovers and knitters. Unlike other neck lights, which need you to press a button at least 3 times for on/off, this neck light only needs one press. Long pressing the power button to turn on a timer for automatic power off after 30 minutes saves your hassles to turning it off when your eyelids are fighting during your reading in bed. Plus, 3 power indicators on the top to inform you how much power is left. [3 Color & 3 Brightness Dimmable] 3 color modes: yellow(1800K) for eye-caring and boosting your melanin when reading in bed; warm white(3400K) for general reading; cool white(6000K) for focus reading. One button on one arm controls the power of advanced LED beads for both heads and a 30-min timer. 2 buttons on the other arm are responsible for color and brightness adjustment respectively. No harsh light, no flickering, blue light filtered, and no more eye strain for seniors, adults & kids. [Rechargeable & Long Lasting] It is USB-C fast and safe rechargeable. Up to 80 hours of powerful, non-diminishing brightness from the included premium rechargeable 1000mAh battery. After a charge, you can enjoy your reading for at least 20 days if you read 30 minutes every day, even at the brightest level. A special narrow beam angle(90°) design can concentrate enough light on the area you positioned while dim enough not to disturb your sound-asleep partner. [Product Guarantee] 1.
