【3 Color Temperatures and Adjustable Brightness】The bedside reading lamp has three color temperature modes: amber (1800K), normal reading (3400K), and focus mode (6000K). The reading lamp has three adjustable brightness levels. Easily switch between brightness levels with a single button press or adjust the brightness by pressing the light button from 5% to 100%. 【USB-C Rechargeable】This book reading light comes with a 500 mAh battery that provides 15–80 hours of continuous light (depending on the brightness level). The included standard USB-C cable makes charging quick and easy. A battery indicator shows the remaining battery level. 【Flexible Lighting Angle】This reading lamp has a clip that opens up to 210°. You can easily adjust the light's angle to direct it exactly where it's needed for optimal visibility. The connection between the fixture and the lamp body is designed to stay securely in place, even after prolonged use or frequent angle adjustments. 【Eye Protection and Memory Functions】The reading lamp emits a soft and even light, without glare, shadows, or flicker, so it's not strenuous for the eyes, even after prolonged use. Each time you turn on the reading lamp, it automatically adjusts to the last used color temperature and brightness; you don't need to adjust it manually. 【Small and Portable】This reading lamp is very small, even lighter than an egg; you can take it with you or hang it on a paperback. Easy to use, perfect for travel, bedside, and reading. Perfect gift for friends, children, and book lovers.
