Characterised by a single coaxial semi-opaque black PVC cable that makes up a continuous line between the various light sources, it can be composed by four different lampshades: Bull, Mark, Nox and Vox. It is possible to use combinations of Bull and Mark or, alternatively, of Nox and Vox in the same ZERO2 system, with a single coaxial cable. Each ceiling rose allows to mount at most 10 lighting fixtures for Bull and Mark, 3 for Nox and Vox and maximum 30 linear meters of coaxial cable. While mixing compositions, 
it would be necessary to use more canopies.
