THE SIMPLICITY OF A LINE THAT COMBINES MINIMAL SHAPES AND RESOLUTION OF ELECTRICAL DESIGN PROBLEMS: THIS IS ELECTROSOPHY, THE CONCEPT THAT GIVES RISE TO THE LETROH COMPANY AND THAT FROM MILAN SOON TRANSLATES INTO A SUBTLE GLOBAL ELECTRICAL REVOLUTION WITH THE REALIZATION OF PROJECTS PRESTIGIOUS

Letroh was born as an innovation lab within L&S Group — one of the leading manufacturers of lighting solutions. Its goal: to create a modular magnetic system that’s easy to install, expand, and reconfigure to meet an architect’s needs. Today, Letroh offers dozens of compatible fixtures and tracks, forming an integrated, flexible ecosystem

Don’t Follow the Flow — Direct It

Everything starts with the NODO system, an innovative track that allows you to position and move sockets, lighting fixtures and accessories with a simple gesture and without tools. The architectural project is free from the rigidity of the electrical system, leaving room for decisions, choices and any changes.
The flexibility of the system translates into economic advantages due to the limitation of masonry works and the reduction of the design limits offered by the freedom to move, add and remove elements as needed

VIAVAI

VIAVAI is a 48V linear system that blends the precision of low-voltage tracks with the elegance of architectural lighting profiles. Designed for both direct and indirect illumination, VIAVAI also comes in a wall-mounted version. Light sources can be snapped into place with a single motion thanks to an innovative locking mechanism

NODO

NODO is a breakthrough power and lighting rail system that allows sockets, fixtures, and accessories to be installed or repositioned anytime, anywhere — without tools, in one motion. It liberates architectural planning from rigid electrical layouts, offering freedom to adapt and evolve at any stage of the project.
NODO is internationally protected by industrial invention patents and attentive to environmental problems through the use of a noble and recyclable material such as aluminum. The essential design and the ultra-thin profile make it an innovative system, with an aesthetic that easily adapts to any type of environment

LEVEL

LEVEL is a new way to approach lighting — combining the lightness of a cable system with the functionality of a track. Its flexible structure allows for easy transport and adjustment to any length. Simple by design, it installs quickly. LEVEL can be mounted on walls, ceilings, or as a tension system between floor and ceiling.
LEVEL uses an innovative power line communication technology for the control and dimming of the LED circuit. LEVEL combined with the ZOOM sources can be connected to systems of different types [DALI, DALI 2, corridor FUNCTION, switchDIM, DSI, 0-10V, CASAMBI]. In combination with the DALI / DALI 2 control, the ZOOM sources can be managed separately, one by one

SURFACE

SURFACE completes the LETROH ecosystem by enabling the use of the same light sources found in LEVEL, NODO, and VIAVAI. SURFACE fixtures integrate seamlessly into interiors — whether wall-mounted, recessed, or ceiling-installed — ensuring visual continuity, consistent lighting performance, and a unified design language across the entire system
