| abstract | The invention provides a lighting device ( 100 ) configured to provide lighting device light ( 101 ), the lighting device ( 100 ) comprising a solid state light source ( 10 ) configured to provide blue light ( 11 ) having a peak wavelength (λ PWL ) selected from the range of 430-455 nm, a first luminescent material ( 210 ) configured to convert part of the blue light ( 11 ) into first luminescent material light ( 211 ) and a second luminescent material ( 220 ) configured to convert part of one or more of the blue light ( 11 ) and the first luminescent material light ( 211 ) into second luminescent material light ( 221 ), wherein the solid state light source ( 10 ), the first luminescent material ( 210 ), and the second luminescent material ( 220 ) are selected to provide at a first setting of the lighting device ( 100 ) white lighting device light ( 101 ) having a CRI of at least 90, a R 9 value of at least 70, and a R 50 value of at maximum 465 nm, wherein the R 50 value is defined as a first wavelength (λ 50 ) in a spectral distribution of the white lighting device light ( 101 ) at the first setting, wherein the first wavelength (λ 50 ) is a wavelength closest to the peak wavelength (λ PWL ) but at a longer wavelength than the peak wavelength (λ PWL ) of the blue light ( 11 ) where the peak intensity (I 50 ) is 50% of the intensity (I PWL ) at the peak wavelength (λ PWL ). |
