Review on YJHome Screenbar Monitor Light Bar - LED Computer e-Reading Lamp - Over Monitor Clamp Lamp - USB Powered - Adjustable Brightness & Color Temperature - Ideal for Home Office by Keith Desjarlais

Installed on a computer monitor 32" 4K. Connects to the USB-A port, has two simple controls, one for on-off level and light, and the other for the cold and warm color of the light.It persists after USB power is removed and restored, which is handy - I plugged it into a USB outlet that turns on and off with my office lights , keeping this light on All modern flat panel displays have an anti-glare surface, so this light (and any other similar monitor light bar) can illuminate your work surface and keyboard without sacrificing picture quality This light reduces eye strain placed my webcam on top of the lightbar, the only difficult part was balancing the webcam and adjusting it the height you're monitoring so I'm not looking directly at the light source. Image taken from my vantage point. The light itself is of good quality and the style goes well with my monitor frame; once installed, it effectively disappears. Highly recommended.
