This one’s only about 9” wide by 19” long, so it wouldn’t make much of a statement. I think you may need something a bit larger for this space. Thinking outside the box, maybe an electrician can wire globe pendants in three sizes at different lengths into one fixture.

You're really looking for a white fixture? Or is that some kind of typo? Personally I think you should paint your storm door to match your front door (which is otherwise invisible) and then use a light like this installed on the wall above the door:

There's not enough protection for anything that hangs, but I guess you could do a fancier flushmount instead of the can you have now, if a gooseneck isn't the effect you're looking for. It's hard to make suggestions with no guidance as to your style, but here are a couple to mull.

It was a typo. Definitely not white. I was actually hoping to do a shorter ish hanging light if possible to take up space as it’s wired for a ceiling mount.

The door will be a walnut wood color door with a storm and white sidelights. Unless someone has a better idea :)

You do have a lot of vertical, so maybe something like this?

Without seeing the whole house it's not really possible to know what kind of statement would fit with the house. Also, even if you get suggestions you like looking at the picture of, you probably should wait until you've actually installed the new door and completed all your painting to see what you've actually got going there. You will need to decide if you simply want to light the door (essentially) or if you want to illuminate that whole setback of the facade.

You didn't ask but I think even in this short-range photo, the look of your entry would be improved if you got a wide and deep charcoal mat and either removed all the plantings completely or settled on 2 positioned somewhere on the porch landing. If you decide on just 2, your choice of planters will probably influence your choice of overhead light.

I O without seeing the whole house we have no clue as to your style so all we do is guess. Post a pic of the whole front of the house and also one of the new door. Post here in a comments DO NOT start another post .
