Fades are LED bulbs that change from once color to the next slowly. You can see the changes between each color because they will actually produce dots before it shifts to the next color. These are great for thumbs, palms. and top of palms. Easily change up the look of your lights by purchasing new colored led bulbs. You can purchase the LED bulbs by themselves or have us install it into a rave light. If you would like us to install it into a housing with brand new batteries please select it from the options.
