I like rope light (at my house) but I also dissagree it is commercial grade, in spite of seeing it in bars and resturants all the time.
They say bulb life is 25,000 hours, I assume that is how long it takes to burn out all of them. The first one (really 18 at a time) may go out in less than a week. It is not something I would want to warranty. I only use the stuff where it is easy to swap out and I do end up cutting bad segments out, using the good part on a smaller run. The stuff I have does say it is wet location listed but it is not OK for locations where it will be subjected to damage.
