The USB lamp measures 4.25 x 3 x 8.65 inches, comes with 12 LED lights that offer you much light for your reading or computer operation. And the rotatable joint allows you to adjust the light angle up to 270-degree. Moreover, in addition to USB port, the LED lamp is also powered by 3 AA batteries.
The USB LED desk lamp is priced at $9.99 USD. If you like this kind of style, jump to ThinkGeek for more details. By the way, don’t forget to check the funky USB key shaped light.
bought one from ThinkGeek, there is no USB!! runs on batteries only.
Their description is very clear. “powered by USB”, “Also can be powered with 3 AA batteries” Maybe you can try it again on your laptop just like what has been shown in the image.
