I am wondering, if this particular low profile box can be considered WEATHERPROOF?

If I want a low profile box for a front porch sconce and I want to avoid having a box sticking out 1.5" is this my best bet?
I looked around and was hoping BELL or REDDOT might have something but couldn't find anything.
