Product Description: Red and Yellow Light: Blue light has been shown to disrupt melatonin production and thus interfere with the body's natural sleep cycle. For night owls who enjoy reading and working at night, this portable reading lamp uses the two warmest colors in the spectrum – yellow and red light. Blue Light Blocking: This warm-toned LED night light has a color temperature of 1600K/1000K, blocking up to 99.99% of the blue light reaching the eyes via electronic reading devices. Our night lamp battery can be fully charged in 45 minutes via the included USB cable, providing up to 30 hours of use on a single charge! Dimmable Reading Night Light: Unlike other night lights, this reading lamp's brightness is 100% adjustable. It features a stepless dimming button design; a long press adjusts the brightness from 0-120 lumens to your desired level. The non-slip clip easily attaches it to any device or book. Lightweight and Portable: Weighing only 100 grams, it is lightweight and portable, perfect for travel. The 360-degree ultra-flexible telescopic pole makes it easy to adjust the angle of the warm light. The LED beads are enclosed in a diffused light shell that emits a soft candlelight effect to create the perfect reading atmosphere. An excellent helper for night reading: the perfect gift for book lovers! Its lightweight and portable design, long battery life, and two rich warm-colored LED lights make it ideal for night reading or working.
