Yeah - its a mixed bag of some people having them and swearing by them and others that say its a grift or aren't sure. My current stance/opinion is that routine yearly maintenance would suffice.Have you talked to your neighbors to see what they do?
In NE FL as well - I'd never heard of them until my wife saw something on one of our community FB pages from one of our neighbors...think we'll go with regular maintenance.I don't know anyone in Florida with UV, but we're NE florida. And even though the bulbs say they're good for 1 year, they slowly start losing their strength from the moment you start running them, so after half a year even if they're still running its only at 50% or so of effectiveness.
