Create a Light Wall with These Magnetic and Modular LEDs

Stu Robarts at New Atlas profiles the Helios modular LED lighting system, which magnetically pieces together hexagonal LED light units on a wall. The individual lights can be turned on and off just by touching them. The modules measure 11 centimeters across and are .4 inches thick, and can be attached to the wall using either nails or adhesive pads. The magnets between each piece double as electrical connections, allowing power from one module plugged into an adapter to be relayed between up to 105 linked modules.
