Spectral measurement of an Arquiled Arquicity R1 LED streetlight installed at Cumeada, Dark Sky Alqueva

During late 2016 the national Portuguese electricity operator, Electricidade de Portugal (EDP), changed the streetlights of the hamlet of Cumeada, Reguengos de Monsaraz, Évora, to white light emission diodes technology (LED). The hamlet of Cumeada is within the borders of the Starlight Tourism Destination Dark Sky Alqueva (DSA). We evaluated in lab the spectrum and the CCT of one of those LED. The results revealed the LED luminaires installed in the hamlet are not appropriate for use in a dark skies reserve.
