I bought a bunch of these and had nothing but trouble with the led bulbs  Once you put them in, they are hell to replace and everyone I had went bad within a few months.  The bulbs are a weird size that you can't buy anywhere.  I solved the problem by buying a screw bulb assembly that worked with more common LED bulb sizes.  One other thing, the mounting plates are big and an odd size, so you'll have trouble finding a back plate to work with your siding.  These fixtures look great, but definitely were not worth the hassle.
