Light Efficient Systems

Light Efficient Systems (LESS) develops distributed lighting systems based on active nanostructured fiber technology with a thickness less than a human hair, offering an alternative to LEDs and discharge tubes. The company claims benefits including high integration potential, uniformity, and brightness. Its product range includes microscopy lighting, workbench lighting, and machine vision products, with applications in automotive, medical, and industrial inspection. Founded in 2012 and headquartered in Lausanne, Switzerland, LESS has raised approximately $39.3M in Series C funding from investors including Venture Kick, VI Partners, W.A. de Vigier Stiftung, FIT, Daniel Gutenberg, and Zurcher Kantonalbank. The company's nanostructured fiber optic lighting technology enables flexible, uniform illumination for precision applications where conventional lighting cannot achieve the required form factor or light distribution characteristics.
