Luminaire designed for under-cabinet and indirect lighting for both professional (shopping center, storefronts) and domestic use. The use of high-performance LEDs results in very low power consumption. Available in five sizes, it is equipped with feed-through wiring for series mounting. The series mounting is done by ensuring the continuity of the light emitted, thus avoiding shadow zones between one ruler and another. The adopted system allows the easy joining of individual rullets in a continuous row, with a single feed point (through-wiring with male/female plug) without interrupting the light "line."  In fact, the adopted screen is designed to diffuse the light over the entire length of the luminaire, without creating shadow areas at the joint. Series connection is possible without additional accessories: the connector to the power cable is the same one that ensures the connection with the next module, if any. Each module still maintains independent lighting from those preceding or following it.
