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

Sofia ★★★★★

Mounted this on the front of my truck as a searchlight and it cuts through fog way better than my old halogen setup. Just remember it's polarity sensitive, so check your wiring before you power it up.

Daniel X. ★★★★★

The brightness on this little cube genuinely surprised me — it throws a clean, wide beam that lit up my whole backyard. Wiring it was simple once I remembered LEDs are polarity-sensitive, so it only works one way around.

Eli ★★★★★

Mounted this on my truck as a searchlight and the beam cuts through fog like nothing I've used before. Just remember it's polarity-sensitive, so double-check your wiring before you power it up or you'll get nothing.
