Background: Needed some light on the side of the boat, as the finger pier she sits at is quite dark. Wanted something to hang on the lifelines that wouldn't offend the rest of the dock residents.
I bought a string of these, liked them so well, I bought 2 more. They do a great job of lighting up the dock when suspended on the lifeline (I bought brass S hooks and attached them to each of the lanterns, the top of the S hooks to the lifeline - easy on, easy off!)
Pros: Really very nice looking and quite bright - they are 7 watt Christmas bulbs. Perfect for the application. I'm going to buy a couple more strings for our back porch.
Cons: I dropped one of the lantern bases in the drink (fished it out.. ohh, the muck of the ages down there 8' below...) and it was because the tabs that attach it were not bent enough to 'snug it down'. Fixed that issue and all is safe now. Can't really call this a negative, but there is a lot of cord on the plug end. Probably 5 - 6 feet, thus the picture is not accurate. I'm going to cut out the extra cord between the strings and shrink wrap the splice. Should work fine.
Anyway, I really like these, and as I said, will buy a couple more strings.
