TukzerMonitor Screen Light Bar with Smart Touch Sensor| USB Powered 5W LED E-Reading Lamp 19-Inch| 3 Color Temperature Modes, Stepless Dimming, 60-Min Timer, No Screen Glare Eye Health Care (White)

I had to return this as my monitor is about 2.8 cm thick and it does not fit on it, so please check the thickness of your monitor and the compatibility of the mount then purchase it, other than that it is a very good light source for desktop, it would be great if they make a version which have a bigger mount at 19 inches. Like they do on the 13 inch smaller varient

The product is sturdy and does the job but cannot be placed on a monitor above 1.2 cm thick.

Its has touch sensor with 3 variant tones and can adjust the brightness. USB power cable alone is enough to connect. Overall good for this pricing segment.

This thing is amazing! It fits perfectly on top of my 24 inch screen and is unobtrusive but the directional light it gives out over my workspace is worth every penny. The light does not spill onto the screen but only on your work space and your keyboard. I love the fact that it is so easy to change the color temperature as I like all my lighting to be of the "daylight type." You can also adjust the brightness and the direction of the lighting area to suit your needs. I have absolutely no complaints about it and I just wish something like this existed long ago when I first bought a computer If you find that you need lighting on your workspace, then just get this thing. Delivered in less than 24 hours. Thank You Amazon...

This is the best you can get for the price.The only thing that concerns me is the after sales and services, so not giving 5 stars :)
