Abstract: A method, device and computer program product for (near) synchronous control of networked lighting devices is presented. In networked lighting systems, a control command sent to the networked lighting devices is limited in length and as such it is not always possible to include the identifiers of the networked lighting devices, as well as the color point and/or intensity level they should change to in a single control command.

This allows a control command to comprise the identifiers of the networked lighting devices, as well as the approximate color point and/or approximate intensity level for (near) synchronous control of the networked lighting devices.
