A lighting device (10) adapted to be used, for example, in the show and entertainment sector, comprises a light source (100) which in turn includes:
a set (200) of electrically-powered red, green and blue light generators (R1, R2, G, B), wherein the set (200) comprises an alignment of laser light generators (R1, R2, G, B) as well as optical combination elements configured to combine, into a beam of red-green-blue (RGB) light, light produced by the individual laser light generators (R1, R2, G, B) in the set, and wherein the set (200) of laser light generators (R1, R2, G, B) includes a first red light generator (R1) and a second red light generator (R2),
mixing optics (400) configured (300) to receive the beam of RGB light from the set (200) of laser light generators (G, B, R1, R2), and
a diffuser (408), intermediate the set (200) of laser light generators (R1, R2, G, B) and the mixing optics (400) and being traversed by the beam of RGB light.
