L-shaped corner joint. 230V rails are linked with this kind of joint to create angled paths. Two tracks can be joined perpendicularly to one another using an L-joint, creating right angles on the ceiling. This can be used to make square or linear patterns, which look great in modern, minimalist rooms. To separate light into different directions or create complex lighting patterns, this type of joint can also be used to create junctions and intersections between tracks.
