Laser Classroom’s LED Light Blox are great to use for a variety of optic experiments. The Light Blox are super high tech LED Light Sources that come in the 3 primary colors (red, blue, and green). Light Blox allow you to demonstrate to your students and children the concept of parallelism, diffusion, and convergence of light (works great with the Optical Block Set, not included).

Each Light Blox unit comes with a removable “slit” cap on the front. When the cap is on, the units produce a ray of light for studying simple geometric optics such as reflection and refraction. When the caps are removed, the units produce a block of light for examining color and shadows. Light Blox are a STEM integrated item that makes learning about physics and optics fun!
