WTF do you want that level of light for? If it's just security all
you are creating are deep balck shadows that whole tribe for tea
leaves can hide in.

Lighting for a working yard is another matter but a few the very
bright point sources can produce glare and areas in their vicinity
that are very difficult to see things in even if they are lit. They
iris in the eye closes up... It may well be better to install more,
but individually less bright, luminaires.

There are a lot of these LED floods out there not all at similar
price points. I'd look for one that says stainless screws *and*
bolts, I have one that has stainless set screws holding the glass
frame in place and I think the rear cover but the nuts, bolts and
washers used for the bracket are chromed steel. Needless to say they
showed rust within 24 hours of being installed...
