A method may comprise: commanding, by a processor, a lighting system to generate a first desired effect in accordance with a first spectral weighting mode; determining, by the processor, a first optimized predetermined variable within a first predetermined domain to generate the desired effect based on the first spectral weighting mode; commanding, by the processor, the lighting system to transition from the first desired effect to a second desired effect, the second desired effect in accordance with a second spectral weighting mode; and determining by the processor, a second optimized predetermined variable within a second predetermined domain to generate the second desired effect based on the second spectral weighting mode, the first optimized predetermined variable being different from the second optimized predetermined variable.

A programming device includes a plurality of signal lines including a first signal line and a common ground line, and a first programming circuit coupled between the first signal line and the common ground line, and including a first configurable switch configured to receive a first switch configuration, the first programming circuit being configured to receive a first power signal from the first signal line and to supply a first programming signal to the first signal line, the first programming signal having a level corresponding to the first switch configuration.

A lighting apparatus includes a main module and an extended module. The main module includes a power circuit, a light source, a first network interface and a controller. The power circuit is controlled by the controller to generate a driving current supplied to the light source by converting an external power source. The extended module includes a function circuit and a second network interface. The function circuit communicates with the controller via the second network interface and the first network interface to add an extended function for the controller to enhance controlling of the light source. When the extended module is detachable from the main module, the main module is operated independently without the extended function.
