Its time for a special issue about LED-Throwies, because i like this simple and illuminated concept so much! A LED-Throwie is a LED mounted on a coin cell battery in combination with some sort of a glueing material, such as a magnet for throwing it on metal. LED-Throwies were invented by the Graffiti Research Lab (GRL), as a destruction free variant of a lightning graphity. LED-Throwies are used mainly for street art or as light effects for events. There are no limitations for endless applications on public statues, buildings, bridges or transport.
