<human>: Sorry for the wall of text!  
  I was getting ready for work on Friday, when I had a knock on my door, which I almost didn't answer because I wasn't expecting anyone. Anyways, it was an electrician who told me that he was changing the light fixture on my front porch (my apartment unit is in an old house) because my landlord thought the street corner was dark, and he told me that he had a key to get inside to check the wiring in the switch that I had to my outside porch light.   
  I didn't think much of it, I just thought he was putting up a more modern, updated light fixture so I didn't really question it then. I get off of work that night, and when I get home there is a bright ass light on my porch. My neighbors were outside, so I thought maybe they installed a motion detector light. 2 hours later and the light never goes off, and I personally cannot turn it off because the electrician came into my apartment and put a flat plate over where my light switch used to be.  
    I flipped my breaker, and the light is wired up to my electric, so my landlord is expecting me to pay for a dusk-to-dawn light to stay on allllllllll night every night because he thinks the street corner is dark at night.   
    I normally receive a typed letter taped to my door 24 hours before something like this occurs for maintenance issues or anything else, but I never received anything for this. Am I justified in being upset over this (the no notice AND expecting me to pay for a light I can't control), and should I call my landlords office when they open back up tomorrow, or should I cap off the wires to kill the light and stay quiet about it?

Can you summarize the given text in a few sentences?
<bot>: Landlord had electrician enter my apartment with NO notice to instal a dusk-to-dawn light outside that is hooked to my electric, and to remove my inside switch to the light so I can never turn it off.
