The invention provides a light generating system (1000) configured to generate in an operational mode system light (1001) having a spectral power distribution with at least 85% of the spectral power in emission bands (111, 121, 131, 141) in four basic wavelength ranges of each at maximum 50 nm width, of which at least three of the four basic wavelength ranges are selected from a first wavelength range of 445 nm +/−25 nm, a second wavelength range of 518 nm +/−25 nm, a third wavelength range of 579 nm +/−25 nm, and a fourth wavelength range of 633 nm +/−25 nm, wherein the emission bands (111, 121, 131, 141) have full width half maxima of at maximum 25 nm.
