Amber, White, or Daylight Modes - Unlike the standard book light, with the NiteOwl reading lights, you finally get a product that offers amber and white daylight lighting modes. True amber lighting (not simply yellow light) eliminates 99% of harmful blue light, reducing eye strain and allowing for a better sleep. Gentle white light aids in better concentration, while natural daylight improves color perception and visual clarity, making these options ideal for studying, working, or crafting. | Long-lasting & Rechargeable - The NiteOwl reading lamp includes a high capacity 1200 mAh rechargeable battery, so you can conveniently read without interruption. The battery quickly recharges and lasts up to 30+ hours (on low) between charges. | The Optimal Amount of Light - With its high-quality LEDs, this reading light produces constant brightness, flicker-free, eye-friendly, comfortable reading conditions. It is designed to be wide enough for reading, yet narrow enough to not disturb your partner or the person next to you. | 360 Degree Adjustable Neck - The NiteOwl's flexible 7" neck allows you to position the light exactly where you need it, creating the perfect private space for you while reading in bed, in your college dorm, or on a plane, train, or bus. The lightweight, portable, & travel-friendly 2.5 oz. construction with padded grip makes this hands-free light easy to clip onto desks, headboards, books, computers, laptops, tablets, and kindles. Use it while playing music, doing a puzzle, writing, or working. | Exceptional Value (2 Pack) - Comes with 2 individually packaged book lights. Store one in your desk, keep one at your bedside, or gift one to a friend, child, coworker, or book lover.
