Gritin’s 9 LED rechargeable book light offers a thoughtfully designed lighting experience tailored to personal comfort. It features three distinct color temperatures - warm, cool, and mixed - combined with stepless dimming via a long-press control, allowing for granular adjustment to suit any reading environment. The eye-caring LED design eliminates flicker and harsh shadows, providing a gentle, strain-free glow that works especially well in dark bedrooms.

The built-in 1000 mAh battery charges via USB-C and delivers up to 80 hours of runtime on its lowest setting. The addition of four indicator lights provides clear battery status updates, avoiding surprises during use. Its 360° flexible gooseneck is sturdy and holds position well without drooping, while the anti-slip clip can securely grip books, Kindles, desks, or shelves.

Despite its small footprint and light weight (64g), the Gritin light feels robust. However, the clip may feel bulky on thinner paperback books, and the flexible neck can be overly sensitive to repositioning. 

Overall, it excels in performance, offering a reliable and versatile solution for anyone needing focused, adjustable lighting in compact form.
