Abstract: The invention relates to a lighting arrangement comprising, among others, means for supporting rods from the ceiling, light fixtures at the lower ends of the rods, and coupling means between the supporting means and the rods, allowing a modular light fixture to be installed with multiple configurations. The invention is characterised in that it comprises one or more nodes, each node occupying coordinates that are pre-determined using a corresponding configuration method, with one or more holes being made in the ceiling or roof, into which a support or rosette is inserted in order to act as a supporting means for one or more pairs of rods at the upper end thereof, said rods being of equal or different length, while at the lower end the rods are connected with the incorporation of the light fixtures and/or bulbs.
