I am an architecture student and I have to make a lot of physical and digital models in my classroom. There's a group of students who insist on working with the dark with one string of Christmas lights. They can see it at their desks but I can't get any light on my desk from it. We often work at night and when it's dark. I can't see my desk when they only have the one string of Christmas lights on and they have confronted me about turning on the overhead lights and they are pissed at me for using the big light.

How can I destroy those lights without anyone knowing it was me? The fire Marshall okayed them in the classroom so beaucracy is out.
