Review on Illuminate Your Workspace with HANUET LED Swing Arm Desk Lamp - Eye-Caring, Dimmable, and Memory Function Equipped Architect Table Desk Lamp for Home and Office by Eduardo Davis

I bought this arm light for my kids because their old light used to only illuminate the left side of the table. With this light, it can be moved to cover the entire table. Installation was super easy. You just need to tighten the clamp on the table and just slide it into the light. The light slides into a deep hole in the clip and stays in place by gravity. I was able to move it around the table and it remains stable. The light is USB powered, but no USB adapter was included. So I plug mine into a USB power hub. It has 3 light temperatures and I have found white light to be the most effective color for her homework. Overall this is good computer desk lighting and excellent value for money.
