This is a really fun LED bluetooth lightbulb. It has so many different colors. You can personalize it to any color you like. The color combinations are endless. It is very easy to use. Just install the bulb in any standard light socket. Turn the bulb on (will be a normal white color) , then download the app on your device ( you can find the app name on the box or use the scan code provided) , make sure your bluetooth is on , the color wheel will come on and you can start the party. It comes with several different modes such as flickering, disco, music, camera, and so on. The app even turns the light on and off. The kids really love this and like to see it change as they talk or play their music. The only con is I could not get it to work well with my Galaxy 6S Active . It would work sometimes and others it would not find the bulb but on my IPAD Air 4 it worked perfectly. I received this product at a discount. All my reviews are based on my own experience and evaluation of the product so that others can benefit in finding quality products that meet their needs & expectations.
