Sometimes it's too dark to see one's work! For those moments, there's a worklight.
Did you get here earlier and see no writeup? Ha HA! It was a test! To, um, illustrate just how hard it is to see your work without a worklight! And now you can see the writeup, because we're illustrating just how easy it is to do your job WITH a worklight. Nope. Certainly wasn't a mistake at all. Just a demonstration of how a worklight can enchance your life.
Phew. I think they bought it.
