We have this hanging up at our home bar. It��s very bright and has a great uniform lighting throughout. We chose the Alien Head light. It was easy to mount on the wall with the little tab and hole. It��s light enough so we just used a thumb tack to hold it up. It��s powered by a traditional USB Type A plug. It does not come with a power adapter. We just used an old iPhone power adapter. The cord is plenty long as you can see we have it hung about 8 feet up and the plug reached the floor. Also, I like how the color and thickness of the power cable is small and almost transparent. It��s around the size of a dinner plate. Not large and not too small. Overall, very satisfied and priced well for what you get. This would make a great gift for any Alien/ET fan.
