What's the proper way to seal a exterior wall mounted luminary from water entry? I was unable to find one for purchase with any sort of gasket, and it appears that any water sheeting down the wall will simply pass through the fixture:

The pictured fixture reads "suitable for wet locations" on UL sticker, and is from a respected brand. There's a weep hole at the marked bottom. I checked every wall mount fixture at several home and building supply stores and they all had the same basic design.

Caulk is an option of course, but caulk must be maintained over time. A retrofit 'mounting block' might help, but those need caulk also. Are there better options for keeping the inside of the light reasonably dry?

Caulk it with a high-quality, paintable silicone caulk like this. I have been using this caulk for 8 - 10 years and have never had to re-caulk after applying it.

What's the proper way to seal a exterior surface mounted lamp from water entry?

Here's what I ended up doing. I applied a bead of paintable silicone caulk directly to the stucco, tooled it for good adhesion, and smoothed it with a soapy finger. This in essence built up a nearly invisible gasket. The fixture already had a weep hole. Fastening the fixture compressed the gasket and made a seal that won't tear with future motion:

I then ensured all three wire nuts were pointed with the open end down, so condensation does not build up and rust the spring wires.
