About us

LUMAX.SI is an interactive sales platform with a digital tool - the LUMAX configurator - for choosing the right luminaires for your space.

In 3 steps to a new luminaire: upload a picture of the room, choose your luminaire and make your purchase. In our virtual showroom, you can choose the right luminaire for your space, all in the comfort of your own home.

Our team has many years of experience in lighting engineering, integrated solutions and consultancy.
