Years of testing and development has made the Educational Light Cube one of the very best light sources available. Upgraded, extra bright lighting, lightweight structure and a variety of elements allow for endless learning and sensory experiences. This light cube is the perfect size for individual and group activities. The flashing mode sends non-verbal signals to students. The white light can be switched to a number of gorgeous colors or can automatically fade from one color to the next for a soothing effect that will enhance quiet time. Perfect for use with transparent objects, games and building activities.
