1. A An outdoor luminaire system comprising:
a support comprising a plurality of first light sources and a plurality of second light sources;
one or more first optical elements associated with the plurality of first light sources;
one or more second optical elements associated with the plurality of second light sources; and
a drive and control means configured to drive and control the plurality of first light sources according to a first profile and the plurality of second light sources according to a second profile different from the first profile,
wherein the first profile defines a first drive output as a function of time and the second profile defines a second drive output as a function of time,
wherein the plurality of first light sources and the one or more first optical elements are configured to output a first light beam having a first color temperature according to a first intensity distribution within a first solid angle, and
wherein the plurality of second light sources and the one or more second optical elements are configured to output a second light beam having a second color temperature according to a second intensity distribution within a second solid angle, said second intensity distribution being different from the first intensity distribution and said first color temperature being different from said second color temperature.
