I don't have any direct experience with Beachcomber other than I have passed by their headquarters right next to Hot Spring and D1 in Vista, CA. In fact, I'm pretty sure they vacated that building since I've been there.
I do know however, that Ultra Violet Light is a very powerful tool for killing bacteria. That's how plenty of Ozone units were made in the late 90's-early 2000's. Most Ozones since then has gone to a Corona Discharge system since you don't want to be replacing their UV bulb every year or so.
Is it their Ozone that is UV and them just trying to market it? Or something completely different in addition to their Ozone unit? Either way, how often does the UV light have to be changed and how much is it going to be to change it?
Just some questions you may want to ask your dealer.
