Type-C Charging: The USB Type-C rechargeable reading light is reversible compared to other micro-USB models and easy to insert. It provides up to 30 hours of wireless reading time after only 2 hours of fast charging. The indicator light changes from red to green once charged. The flexible and ultra-long arm of the reading light can be wrapped or bent into the desired shape and held in place, providing you with a stable and optimal lighting angle. Use the provided fixing rope for double fixation. No need to frequently adjust the reading light, free your hands and focus more on your task. Soft Light Eye Protection: Each arm of the reading light is equipped with two LEDs (1 warm and 1 white) and offers 3 color temperatures: warm light, white light, and warm white light. Each head has a separate touch switch, allowing you to quickly select the mode with a simple click. The narrow beam angle allows the reading light to illuminate your space without disturbing your sleeping partner.
