1. A method for near synchronous control of networked lighting devices, the method comprising:
receiving a target color point, in a target color space having a target color space resolution, or receiving a target intensity level, in a target intensity space having a target intensity space resolution, and further receiving identifiers for networked lighting devices that are to be synchronously controlled to emit light based on the target color point or target intensity level,
determining whether a target control command based on the received identifiers of the networked lighting devices and the received target color point or the received target intensity level will exceed a maximum control command length, and if the target control command will exceed the maximum control command length:
determining an approximate color space resolution, relating to an approximate color space, of a lower resolution than the target color space resolution, or an approximate intensity space resolution, relating to an approximate intensity space, of a lower resolution than the target intensity space resolution, based on the number of networked lighting devices that are to be synchronously controlled, and further based on the maximum control command length,
determining an approximate color point in the approximate color space based on the target color point or an approximate intensity level in the approximate intensity space based on the target intensity level, and
sending an approximate control command based on the received identifiers of the networked lighting devices that are to be synchronously controlled and the approximate color point or the approximate intensity level.
