Claim 18:
19. A system for exciting two different chromophores in a microorganism, the system comprising:
a luminaire having:
a first light emitting element (LEE) that emits first light at a first pulse frequency with a first wavelength between 380 nm and 750 nm; and
a second LEE that emits second light at a second pulse frequency with a second wavelength between 380 nm and 750 nm;
wherein the second wavelength is different to the first wavelength;
wherein the first and second pulse frequencies are different;
wherein the first and second pulse frequencies are integral multiples of a fundamental frequency; and
wherein a pulse train of the first light has a controllable phase difference with respect to a corresponding pulse train of the second light;

a driver coupled to drive each LEE with an independently variable duty factor and an independently variable peak radiant flux output and to control the phase difference;
a sensor configured to detect a parameter of an environment of the microorganism; and
a controller configured to adjust, based on the parameter, either or both of a peak radiant flux and a duty factor, in either or both of the first light and the second light.
