Synchronized light board and heat sink rotation for illumination beam redirection

A light fixture, comprising:

• a housing;
• a first light emitter member rotationally coupled to the housing;
• a first intermediate heat sink defining a first semicylindrical heat transfer surface, the first intermediate heat sink fixedly and thermally coupled to the first light emitter member;
