First of all, I am not a native English speaker, please forgive me.
I recently rented the room I am currently living in. On the ceiling there are fluorescent fixtures like the picture below (I found this image on the Internet, but looks very similar to mine).
When I first came, two lamps would light up when I turned the light switch on. (I just found that it had 3 lamps moments ago. So, there had been one lamp that did not light up all along.) But, two were too bright for me. I had been thinking about opening the cover and taking one out (leaving only one) but I was just too lazy.
Yesterday, suddenly one of them would no longer light. So currently only one lamp (out of three) is on. The brightness of one lamp is fine for me, but I wonder if the two non-functioning lamps are still drawing power? Is it OK to leave the non-functioning lamps there?
As I said earlier, I rented this room and I will leave here in 9 months. So if there are no downsides other than they do not light up, I do not want to take the hard work of removing/attaching the cover and taking them off.
