BIRO40 consists of a torsion-resistant aluminium profile and an LED circuit board providing either monochrome light in tuneable white or RGBW light colours. Available as a recessed, surface-mounted or pendant luminaire, as well as in different lengths, the lighting system integrates well into a given architecture and its room dimensions. Consistent with the lighting concept, it allows different arrangements: depending on conditions, a linear, a rectangular and an L- or U-shaped installation are available.
