- Three colour temperature options: amber light (1600 K), natural light (4200 K) and cool white light (6000 K). Amber mode filters out 99.9% of blue light, protecting eyes when reading. - Five-level brightness with memory: five levels of adjustable brightness, plus a brightness/color temperature memory function for convenient later use. - Mini folding and flexible positioning: small enough to use independently or docked to a book. The lamp head rotates 90° counterclockwise and 90° clockwise, and the flexible holder can be adjusted to achieve the best viewing angle. - Lightweight and portable: made of high-quality ABS and metal; compact and easy to carry. Foldable design allows clipping between pages or carrying in a bag, making it suitable for reading in bed or while travelling. Use scenarios: - Bedtime reading without disturbing others, thanks to adjustable colour temperature and brightness. - Reading on planes or trains, clipped to a book for stable, focused light. - Travel or study sessions in dim environments, with a compact light you can clip to pages or keep in a bag.
