The Baseus i-wok Screen Hanging Light provides three light modes-white light, mixed-light, and warm light. It has a colour temperature range of 2900K-5000K. It is more comfortable and protects your eyes for more efficient work and study. It is easy to install by clipping the product on top of the computer screen. The clip range is 1-3cm. Any USB socket can power the LED task lamp, whether it's a computer, a mobile phone charger, or a mobile power source. This product adopts an asymmetric light path design, which only illuminates the desktop space, reduces screen reflection, and effectively protects the eyes.
