The 1PUCK LP by MINIMIS, a studio based in Austin, Texas, and run by Luciana Misi and Alex Lorenz, is the world's smallest recessed floor light. Barely the diameter of a US half-dollar, it looks like an enlarged piece of hardware, which allows it to blend into whatever material it is screwed into.
Despite its diminutive size, the 1PUCK LP by MINIMIS emits a strong, directional glow that illuminates pathways and other perimeters more than sufficiently. Although it is purported to be used in floors, this light can be used anywhere on walls and ceilings as well. It has been designed to run on 12 volt DC, plug-and-play on photovoltaic systems or discarded electronic waste such as old cellphone chargers, laptop chargers and more.
