A colour tunable lighting module is described which includes at least three solid state lighting emitters (such as light emitting diodes) and at least two wavelength converting elements (such as phosphors). The three solid state lighting emitters are formed of the same semiconductor material system and the light generated by them has dominant wavelengths in the blue-green-orange range of the optical spectrum. The two wavelengths converters are used re-emit some of the light from two of the emitters in broader spectra having longer dominant wavelengths, while the third emitter is selected to emit light at a wavelength between the dominant wavelengths of the light from the two emitters and the two converters. A control system may be employed to monitor and control the module and the lighting module can be optimised for tunable high colour quality white light applications.
