This is such a cool disco light! It is so colorful! The light show it puts on never gets boring because it is constantly changing. The colors are so pretty! It changes between red, green, and blue. It has mini led bulbs around the bottom of the disco light that are constantly changing also. There are 48 LED bulbs. It is powered by an AC wall outlet. You can set it on a table, or hang it on the wall. It has two holes on the bottom for easy hanging. It is lightweight and made well. It has a long life of 5,000 hours. The light is 5 inches in diameter. I find it fascinating just as much as my 10 year old son! He can not wait to show it off to his friends when they come over.
