Hi Erin, sounds like a power surge which blew the bulbs.When you switch anything on ,you get a power surge, eg if you have a 60 watt bulb and the surge goes up to 65 watts the light will likely blow.This only happens in a spilt second.[the surge].However,if you are not happy i advise you to get the electrics checked out. The most common bulb to go is the bathroom one[cos of dampness].At least it does in mine!
