The bulbs act as repeaters for Hue stuff. So long as you don't have any bulbs miles away from anything then you'll probably be OK with one bridge. Can't remember exactly but each bridge can handle something like 75 things attached to it.
my mums already intrigued by the idea of automatic hall lights and have the lights change based on time of day in her little flat so I think the second bridge will be put to use there instead.
