low profile junction box for we location light

I have a pergola similar to this one but with 3 posts that are each 5.75" wide:

I need to mount lights on the posts about two feet down from the top. I want to run conduit directly into the light fixtures. I don't want to have to mount the light fixture on a junction box and then have the conduit go into the junction box. The only light I've found that would work for this is this one:

But the customer does not like it. Anybody know of another wet location LED/CFL light fixture that is at most 5.75" wide and would allow for conduit to go directly into it from the top?

Or do you know of a low profile aesthetically pleasing wet location junction box that I could use?

Thanks!
