3 Colors & 6 Adjustable Brightness Levels Unlike other lights for reading in bed, the Glocusent neck light has 3 useful color temperatures: Yellow (3000K), Warm White (4000K), and Cool White (6000K). It has 3 brightness levels per arm and various combinations of reading light settings to meet your needs. For example, a yellow light for general reading; a warm white for studying; a cool white for sewing or precision crocheting. Rechargeable & Long-lasting Compared to other Micro-USB book lights, our rechargeable USB-C LED reading light is user-friendly and safer for old and young. This is because USB-C is a \"one-size-fits-all\" design that is easy to plug in from either side. In addition, the built-in 1000 mAh battery provides a battery life of up to 80 hours (depending on the e-reader's lamp settings). It keeps you away from daily charging with non-diminishing light. Eye Care & Ergonomic Design Our reading light for books produces no flickering or glaring light and is gentle on your eyes, it is a perfect bedside lamp for reading at night. It has an ergonomic shape that adapts to your neck; the arms are flexible and adjustable, making it easy to find the most comfortable angle - an ideal lighting aid for hands-free activities.
