Of course, wall switches aren't going to work if you're wanting to control bulbs that aren't in wall switch-controlled fixtures. And as expensive as Insteon wall switches are (~$42 from Amazon) they might not make economic sense unless each switch controls at least 3 or 4 bulbs. White smart bulbs from Hue & GE are normally about $15 each, can be had for as little as $10 each on sale (I just picked up 3 GE Link bulbs at Target for that price), and have an estimated life expectancy of 20 years.
