Spectrometer measurements on a NM day, a full sun day and in a growth chamber. We simulated the luminous intensity of the moon in a growth chamber using four types of LED programmed at the main wavelengths 450 nm (blue), 660 nm (red), 730 nm (red) and in white light to emit a light intensity of 6 lx (< 2 PAR). Light intensity spectra (cd) and histograms of the color quality scale (CQS) and light values measured by a Rainbow-Light Portable Spectrometer MR-16 PPF under a full moon, a full sun day and in a growth chamber are shown. LHY and PHOT1 gene expression were analyzed by RT-qPCR. Plants exposed to this artificial ‘moonlight’ showed atypical transcription at ZT21 (dashed line)
