6 Brightness Levels & 3 Colour Modes Each lamp head has an independent switch for 3 brightness levels and 3 colour modes. You can switch on only one side to make the area where your husband or wife sleeps darker. Make reading in bed at night no longer a bother to others nearby . Designed for Nighttime Reading Unlike other neck lights, our neck reading light provides a special amber mode for reading in bed at night. It is eye-caring with blue light blocking to avoid your eyes strain, and stimulate your body to produce more melatonin naturally for a better sleep after reading . Perfect for Knitting Simply put the led reading light around your neck so that both hands are free when knitting or crocheting. This practical neck lamp helps you just focus on what you are doing without worrying about the illumination. And it is easy to see stitches clearly especially when dealing with dark colours . USB Rechargeable & Long-Lasting The reading light for books in bed features rechargeable 1000mAh battery, provides up to 80 hours wireless reading time after a quick charge of just 1.5 hours. With the included type-C cable, it charges like a cellphone without need to spend money on buying batteries
