The lights are beautiful.  I like the fact that you don't see the light bulb but they still give off plenty of light. We have  horizontal siding with a 7" width exposed to mount the light on.  We wanted the lights to lie flat against the house without gaps so my husband had to make adjustments with shims.  It worked out beautifully.  We especially wanted to make sure that nesting insects couldn't get behind the light as that is an issue in our area.  The lights would have worked out fine without the adjustments but not quite what we would have been happy with.
