Underscore perfectly defines the geometrical structure of spaces perfectly, in three versions: 6, 15 and 18 mm versions. Miraculously, these few millimetres of light create simple, yet highly dynamic shapes, and the luminous lines become one with the architecture. They subtly highlight architectural features and create magical atmospheres by giving surfaces a sense of infinity. Underscore is a complete system for highlighting paths, designing textures and even adding colour to environments. A new trend way to rediscover dark spaces using graphic light to give shape and character to shadow.
