Installed them in 2008, took them through some very nasty weather with lots of water over the bow and they keep on shining just fine.
I also do have the Orca Green Tri-Anchor light, installed in early 2009, while the mast was down. When I ordered the Tri-Anchor light, which is normally supplied with only a 3 feet or so pigtail, I was able to talk them into supplying me with a customs length wire of 75 feet because I did not want a splice inside the mast. They charged extra, of course, and it took an additional 3 weeks or so but they delivered.
