You said the 4" base could be even better if it were bigger. So here it is, 6" wide and twice the LEDs. Includes 40 red, green, blue and white LEDs with a multi-function lighting feature that will bring objects to life. Features include many color combinations that will continually change or can be stopped on any color combination. Batteries will last 10+ hours. The base includes an acrylic cover to provide a continuous solid surface for your object to rest on.
