I would just swap out the second one with a flush can…

If the ceilings are the same height why not just match them .

Yes, I think it is fine.

I would go with the SAME shape for all three, just different “types” vs. different “shapes.” The third one doesn’t go with the first two, in my opinion. If you prefer the third “shape” best, can you do it in the other “types” as needed?

The third one size is too small for the ceiling size by the door-it is 2” smaller (diameter) than the other flush mount fixture.. otherwise would’ve used 2 of those…

@Susan Marie if I understand you correctly, your favorite of the three lamps is too small. I found extremely similar light to your favorite. One was 9?" and the other 10". What size did you want? Would a 12" round ceiling medallion fix it?

Thank you- yes, the one I have is 10”. I need at least 12” to not look too small. The medallions won’t help as the globe gets lost in the wide flat ceiling there. Thank you for trying to solve my problem!

@Susan Marie I'm sorry I didn't have a workable solution. So I guess we need a light with a 12" globe then? Ok! 😁

This one is 13" diameter, but it's not silver like the one you like.https://www.lampsplus.com/products/merrimack-collection-2-light-flush-mount-ceiling-light__33759.html

This one is 12" but bronze again.

So the first one you pictured is semi-flush and 13" and you think that will work in the wider part of the hall. And you want to put one of the smaller flush mounts in a narrower part of the hall? Sounds ok. Same color metal and same type of glass.

Thanks everyone—didn’t work out- went another way
