Not sure who made these posttops but I do know they use HPS and the lamp is actually horizontally mounted inside the white dome. The PC is inside the finial.
This looks very similar to the post-tops you find in Breckenridge, Colorado. A slight different design but VERY similar. The ones there are HPS as well.
Even the ones there have the little white thing on top.

I wonder who makes this as well.
But still VERY similar to this one. I wonder if the ones in Breckenridge are the same manufacturer as the one in this picture.
