tu 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.
Dyena , the firm behind the Helios system , explains that the aim is for users to be able to turn the interior architecture of a space into a light source. A few of the modules could be use together at a desk to provide light when working or a whole wall could be covered in them. Each 6.3 W unit is said to produce 400 lm , which is about the same brightness as a 40 W incandescent bulb or a 6 W LED bulb. Each module added , therefore , will be like lighting a room with an additional bulb and up to 105 modules can be joined together in one circuit. A display can be bigger than 105 modules , but they must be on different circuits.
