There is provided a high brightness lighting device 10 comprising a laser 1 for providing high brightness coherent light and a light scattering element 2 arranged for receiving light from the laser. The light scattering element comprises luminescent material adapted for converting part of the provided light into a different wavelength. The light scattering element is further arranged to transmit and scatter part of the provided light without conversion. Thereby, upon receiving the coherent light, light being outputted from the light scattering element has a dual lighting effect, due to the outputted light comprising high brightness incoherent light originating from converted light providing a sparkle lighting effect, and coherent light providing a speckle lighting effect. Further, a corresponding lamp 30, 40 comprising such a lighting device is provided.
