My Aunt Marian had two of these in her living room. I loved them. As a 3 or 4 yr old child, I can remember digging my toes into her white flokati supershag rug, my hair tangled up in the blood red velvet drapery, staring up at the velvet bullfighter paintings on either side above the white vinyl foldout couch. I thought those lamps were where the tomatos came from to make her meatball sauce. (They were the same color). Man, I miss those meatballs! Her house was so cool!

My suggestion would be to suspend your pendants centered on the upper glass window approx 24" or so down from ceiling. Sometimes, with a pitched ceiling, the light will suspend slightly to the downside of the j box even though the box is centered in the space. I would go for a round shaped pendant under 12" diameter each. My preference would be to illuminate wall and ceiling as well as down. Keep it simple because there will be a lot of them in a line. Will there be artwork on the walls or anything that might want a more focused light?

I can't really make out how the globes attach to the fixture from the pictures. Normally I would think a washer inside the globe would work, but that doesn't look possible with the new globe. But, I think that you could attach a washer, if you can find one that is large enough yet has the opening size that you need, to the top of the globe. Maybe something brass so it looks like it should be there. You would need a very strong, permanent adhesive, something like JB Weld.

I have the same pendants as @mihelene. I have NO issues with glare although plenty of folks on this site warned about that and said it would be a problem ----- it has not been. I will second, though, that they do have to be cleaned regularly and that is another task to keep up on; although I often wonder if I had something not clear, surely it would be getting just as dirty and need cleaning.....? Maybe I should just feel grateful that my lights make me keep a cleaner house. ;) Also, it seems to me that the height of your ceiling isn't such an issue as the height the pendants are recommended to be hung is 30-36" above your counter top regardless of what height your ceiling is. I have 9' ceilings and my globes are about 15.5" long. I don't think an 8' ceiling would be a problem. (My sister in law has 8' ceilings and she just installed fixtures similar to your posted picture. They seem bigger than mine (perhaps just in width) and they look good.)
