The NoBlue Amber Book Light features the BlueBlockLight proprietary amber spectrum— a flicker-free, warm light that is 100% free of any sleep-disturbing blue light! It has 360-degree flexibility, making it adjustable to the exact position you need. This is especially useful when reading in bed with a partner. It is a lightweight, 100% blue light-free, portable light which is perfect for using anywhere you need some reading light; whether that be while camping or travelling, using in the baby’s nursery, or if you’re sharing a space with someone else. It is 100% free of any sleep-disturbing blue light, which means your body won’t be robbed of restful sleep and recovery after use. A protective rubber pad on the clip makes clamping secure and stable and ensures that book pages won’t be damaged. The large clip has a flat base to convert it into a table lamp, so you have a blue-free light source wherever you need it! FULLY RECHARGEABLE—This book light is powered with a rechargeable lithium battery (1200mAh) that allows up to 30 hours of use before needing to be recharged. The NoBlue Book Light has three brightness settings of 25%, 50% and 100%, allowing for an easily adjusted variable brightness of 20, 40 and 80 lumens.
