The LED Cube is a really bright light, making a perfect searchlight for your vehicle or beacon on top of your lighthouse. An LED is a polarity- sensitive device, which means current only flows in one direction. If the LED does not turn on when you connect the wires to the battery, try reversing the wires to reverse the current flow.

The LED Cube is just one part of a circuit. Add a battery to power your creations, a motor to make them move, and a switch to take control!

  • Fits your bricks! Compatible with major brick brands
  • Seamless circuit connectivity (no soldering) 
  • Safety-tested & approved for ages 8+
  • Created by STEM teachers, tested by kids
