OHM Electric LED Desk Lamp White LED desk light with USB power and smartphone stand. I purchased this but never had a chance to use it, so it has been stored at home. The arm can be bent freely to adjust the angle. It uses USB power, so if you want to use it with a wall outlet, you will need to use your own "USB port adapter". Comes with the original box and instruction manual, and the operation has been confirmed. - Brand: OHM - Model Name: DS-LS12USB-W - Color: White - Features: USB power, with smartphone stand - Light Source: LED
