Three colors, dimmable: The reading light offers three color settingswhite, warm white, and natural white. A single press of the button changes the color, while a long press and hold for more than 2 seconds adjusts the brightness. Adjustable brightness allows you to customize the lighting for different reading environments. Book light clip: The built-in clip on the back allows you to securely attach the light to books, enabling hands-free reading. The light features a flexible silicone gooseneck that can be bent to direct illumination precisely where needed, without disturbing others nearby. Convenient storage: The book light includes a side slot to neatly store the gooseneck when not in use. Compact and portable, it takes up minimal space and is easy to carry. Sized similarly to a car remote, it is ideal for studying, reading, working, traveling, or camping.
