Abstract: A device to monitor museum lighting has been developed and tested. It allows to control in real time both Visible and UV spectra. The device monitors, using five different channels, the colour rendering of a lamp and the ultraviolet part of the spectrum impinging on exhibit objects. The control on colour balancing of illumination allows to avoid the use of aged or deteriorate lamps. The continuous monitoring of UV and blue radiation is fundamental for avoiding serious damages on the exposed artwork. The device is compact, cheap and simple: it could be used in museums to control room illumination or it can be placed near important artworks to provide their lighting history.
