kreon diapason is one of our most iconic signature luminaires. It embodies the pure kreon product design and is the perfect example of an elementary tool of light to give architecture a timeless character. This first generation kreon diapason has been updated with full LED and LED retrofit sources. kreon diapason is available in two sizes with a choice of black or white painted finishes with the option to add cylindrical glare preventors for maximum light restraint. kreon diapason can be M10 thread fixed, or surface or track mounted on a gearbox accessory.
