There are tons of questions about installing and replacing ceiling lights already, and I was looking through them but I didn't feel like checking 106 pages of results to make sure my question isn't a duplicate of another one! So... here we go. :)
I am very illiterate when it comes to electric installations and wiring, but I have a dated flush mounted ceiling light in a hallway I'd like to replace. Today I removed all the parts I dared to, but now I'm not sure where to continue.
First of all, what is all that insulation stuff inside the base of the old fixture? I'm hoping I didn't just expose myself to asbestos...
Second, many of the new fixtures I've looked at are for two bulbs and this one is just for one bulb. Is there any way I can use the existing wiring to install a two-bulb light fixture?
Third, I've seen pictures and read about there being a ceiling bracket that the light connects to. Will that be above this round box? I don't want to go too far and remove everything from the ceiling if it's not necessary.
I haven't bought a new fixture yet, but decided to get this much done for now.
