I'm having trouble changing a ceiling mounted adjustable fixture lightbulb. So there's two issues: one, the metal housing is loose and when I try screwing it in, there's a lot of grinding and varying pressure and popping. I'm wondering if the bent section means it's broken? And two, even if I do get it reasonably tight, the light bulb socket rotates independently and won't allow me to loosen the bulb to change it.
Thanks all. I know this may be a simple question, but my level of home improvement skill is quite low; and with how high up and hard to see it is, I'm afraid of breaking something since I don't know what I'm doing.
