【Dual-head LED design, better lighting】Dual-head reading lights cover 120% more area than single-head lights, equipped with 14 high-lumen LED lamp beads and 90° adjustable lamp wings, providing precise work lighting. You can switch between three colors: warm light/white light/cold light, and can be dimmed steplessly (10%-100%), effectively reducing eye fatigue when reading, handwork or working at night. 【3 color modes and 8 brightness levels】Our reading lights are designed for reading in bed at night and provide 3 different color modes. Amber light (1600 - 1700K) creates a soothing atmosphere, natural light (4000 - 4500K) brings a comfortable reading experience, and white light (5500 - 6000K) helps improve concentration. 【USB-C Fast Charging, 7 Hours of Marathon Reading】The wireless reading light is equipped with a 1000mAh battery, which can be fully charged in 3 hours via USB-C, and has a battery life of up to 7 hours (you can read 3 novels ) and can be securely clipped to your e-book reader/headboard/backpack. Anti-tangle adjustable eye protection LED lamp beads, perfect for travelers/students/bedtime reading. 【360° Flexible Clip & Ultra-thin Portable】This foldable reading light revolutionizes portability with a 30mm slim profile (thinner than a coin ) and 360° rotating gooseneck lamp + reinforced clip.
