Thought I'd check out the lounge here ... and have a question ..

My wall switch in our master bedroom has a wall switch at the entrance. which in turns feeds both our outlets ( 120v) so when we enter the room we hit the switch and the bedroom lamps on both sides of the bed come on .. my query is why does one of the lights or lamps take just a split second longer to come on over the other light ..? both lamps are identical and both bulbs are 60w .. ( not sure if the manufacturer of said bulbs are the same though) ....


Merry Christmas and Happy New Year all ..
