I’ve got 6 Hue White bulbs and 3 dimmer switches scattered around the house (bedroom, office and kitchen), having 3 in the kitchen area makes for some impressive lighting scenes by linking multiple bulbs to a single switch. The dimmer switch can be programmed to do different actions on multiple presses (e.g. 1 press turns it to the last state, 2 presses sets it to dimmed, 3 presses to night light, etc.), that comes in handy in evenings.
Adding the Hue Bridge really opens you up to home automation and from there a downward spiral to endless accessories.
