When I moved into my apartment there were - as expected - no lights. I quickly got the lights up in the study and the bedroom, but the other rooms required some drilling into the ceiling. Since I had no impact drill I just filed the whole project under "later".
The problems soon became apparent. As soon as it turned dark outside - and trust me, in Sweden during winter, that is pretty much all the time - my hallway became a pitch black hole of darkness. Having guests over was fine, until it was time for them to go home. Then I had to send them down a corridor of darkness with the promise that "the door is at the end, just keep walking straight ahead".
Come to think of it, had this been the US, I would probably have been sued already.
But no more! My new lamp shines with the strength of a thousand suns!
