I agree with you that the glass shell lamp is too small for your bedside table. The other ones are a better scale. As for whether to put one or two lamps on the foyer table, I think it depends on how many other pairs you have in the same sightlines and how much light you want because either arrangement can work.

I like the bigger lamp on the nightstand.

As for the foyer table, I prefer one lamp with decor on the other side I think. If the picture had the wall space behind it, it would be easier to tell though.

Looks nice though and congrats on the house!

I like the larger one and I'd love to see it with a light beige textured shade.

I like the larger lamp on the nightstand.
And I like the skinny lamp on ONE end of the hall table.
Looks nice! I'm currently in lamp dilemma myself LOL
Why is it easy to tell someone else what looks good in their house but not so easy in your own? :o

Thanks, all! The wall above the foyer table is a vaulted ceiling that is probably 15' so I will do a large mirror above the table. That is why I purchased the clam/shell lamps - they are substantial in size and I thought would work well with the vaulted ceiling. I am returning this weekend, so I will take a better picture showing the wall.
