Magnetic and modular LEDs can cover a wall in light
whole wall. That is the principle behind the Helios modular LED lighting system, where hexagonal units can be joined together magnetically to cover any area and turned on or off individually by touch. The Helios system is similar to the Nanoleaf Aurora Smarter Kit, which uses 8.25 x 9.4 in (21 x 24 cm) triangular panels in a similar way. The hexagonal Helios modules are smaller, though, at 4.3 in (11 cm) across their longest span and 0.4-in (1-cm) thick, and do not feature the smart and color changing properties of the Nanoleaf system.
