Claim 1:
2. An illumination device apparatus, comprising:
a user actuatable element
communications interface circuitry;
memory circuitry; and
control circuitry communicatively coupled to the user actuatable element, the communications interface circuitry, and to the memory circuitry, the control circuitry to:
receive, via the communications interface circuitry, a first signal that includes information indicative of a maintained actuation of the user actuatable element;

determine whether the duration of the maintained actuation of the user actuatable element exceeds a defined hold time, wherein the defined hold time includes a mask value
greater than or equal to a temporal duration of the greatest communication latency between at least two of the plurality of networked illumination devices;
retrieve, from the memory circuitry, data representative of a starting value associated with an output parameter for each of the plurality of networked illumination devices responsive to the determination that the maintained actuation of the user actuatable element exceeds the defined hold time;
cause a communication, via the communications interface circuitry, of a command to at least one other of the plurality of networked illumination devices, wherein the command includes an instruction to begin changing the output parameter of each of the plurality of networked illumination devices;
receive, via the communications interface circuitry, an input indicative of discontinuation of the maintained actuation of the user actuatable element;
determine an ending output parameter value associated with the output parameter for each of the plurality of networked illumination devices responsive to receipt of the input indicative of the discontinuation of the maintained actuation of the user actuatable element;
cause the communications interface circuitry to communicate the determined ending value associated with the output parameter to each of the plurality of networked illumination devices, the communication to cause each of the plurality of networked illumination devices to reach the determined ending value
over an adjustment period less than or equal to the mask value, wherein the adjustment period commences with the receipt of the input indicative of the discontinuation of the maintained actuation of the user actuatable element; and
cause a replacement of the data representative of the starting value associated with the output parameter with data representative of the determined ending value associated with the output parameter.
