Abstract: A tunable lighting system for controlling the intensity and/or correlated color temperature (CCT) of light output from a tunable light source. The system includes one or more switch modules for sending user commands for a desired intensity and/or CCT. A driver of the tunable light source drives one or more channels (508) of a tunable lighting module using an adjustable constant current circuit (604), a DC-DC converter (602) with an adjustable output voltage (Vadj) and short circuit protection circuit (610). In some embodiments, calculation of drive current for the light source is performed in real- time using parameters of the tunable lighting module. In some embodiments, a network collision avoidance process avoids network collisions by assigning any one of a plurality of switch modules on a network as a master.
