Abstract
Methods and apparatus for controlling illumination. In one example, one or more multi-color light sources are controlled based on one or more interruptions of power supplied to the light source(s). In another example, a pool or spa is illuminated by one or more multi-color light sources that may be employed as individually and independently controllable devices that may be controlled based on one or more interruptions in power. In another example, the selection of a particular illumination program for such light sources (e.g., by one or more interruptions in power) is indicated to a user via the radiation generated by the light sources.
