We found the IKEA one pictured (first one) to be worthless. It gave off no light. It is rated for too small a bulb I put two of them in our basement hall years ago. For our new guest room we decided we didn't want to go with such a BAM fixture it is what people noticed when coming into the room. I think there are times the fixture is part of the decor and make a statement but for us the guest room wasn't one of these places. We replaced the circa '70s builder's grade square glass cover with a frosted round one. Not a huge step up by any means, $6.00 at Menards..but it updated and can hold 60 watt bulbs.

What size back plate do you need? Your title says black/silver or bronze...what finish are you looking for? What is your budget? Can you be a little more specific with the help you need?

Do you have canned lights all around that fixture? It's very possible that your light is a refit that changes a canned light into a hanging fixture. They screw into an existing can, like a light bulb, and hang by a thick cord. If you have this, you can buy a new fixture, or change back to a can. See example: Canned light Conversion Kit

I think a triple light is too much. 9 lightbulbs? you could land a plane in there! go w/a double light fixture. 6 bulbs is plenty. any chance of removing that huge mirror, doing two separate mirrors, and installing sconce lighting ? (these are pendants, but sconces would give the same look) lighting like this is so much better for doing make up or something like this?
