MadebyLight is a designers’ alliance for the lighting culture. Our activities include creating lighting designs and developing design methodology tools. Thanks to the realistic modelling we make our partners can make efficient decisions - either independently or relying on our services - not only concerning lighting but also with regard to light modelling and architectural and interior design issues. Another important area of our activities is the development of a database-aided methodology for improving efficiency and minimising defects in the graphic design and data processing phases of lighting design.
