I did the same thing and it was good for a long time, then one day I came in to find the maintenance people replacing it - thinking it was broken - instead of just twisting it back. I guess they weren't too bright (lol).
Could be worse. I worked in an old building in London which I think used to be a warehouse. It was renovated but the lighting was very low and they said they couldn't install stronger diffused lighting because of the local code. They eventually added hanging spotlights. Very bright and very narrow. But they would always end up shining right into someone's eyes. Every once in a while someone got annoyed by one and would rotate it in some other direction, only to piss someone else off.
It helped a lot until maintenance would come in at night and "fix" the light and I'd have to do it all over.
