LED Reading Lamp Clamp Light USB Rechargeable Book Lamp Small Book Light Feature: Customize Your Lighting: The book light in bed has 3 color temperatures and 3 brightness settings. The brightest setting easily illuminates 2 full pages of any size book, and the lowest creates a private reading area for you when your partner is sleeping next to you. Rechargeable and Long Lasting: The built-in battery provides 4 to 70 hours of consistent and eye-friendly light depending on the brightness setting. In just 1.5 hours, you can fully charge the rechargeable book light with the included micro USB cable. Ultralight: The mini reading light is so lightweight (only 1.3 ounces) that you hardly feel the extra weight when you clip it onto the book. The foldable design makes it take up very little space like a mouse and is easy to store for travel. Well-designed clamp: The LED reading light clip opens about 1.2 inches and provides a secure grip for thin items, which is very suitable for books, e-books, tablets, etc. The non-slip clip is also padded with a soft sponge to avoid leaving marks on your book and e-book cover. Flexible metal gooseneck: The gooseneck is flexible so you can position the light exactly where you need it. And it is covered with metal material, which increases the durability and lifespan of the book reading lamp and prevents the lamp head from wobbling during use.
