Abstract: An illumination system and method is disclosed for maintaining a consistent change in illumination value among a group of illumination devices whenever a change command is manually sent from a keypad to those illumination devices. The consistent change results from maintaining a common start illumination value among not only the group, but also the keypad which controls the group. From the start illumination value, the keypad can then compute an end illumination value depending upon the amount of time that the increase or decrease in illumination value button is depressed and held.
