Savio UVinex Purifier Replacement Bulb, 18-watt

We bought the last one in August 2022. We use it 24/7 from spring start up (end of March-early May) through late October, early November. The bulb just went out and we ordered a replacement here at the end of May 2025. Savio stands by their products too, so I feel confident they will replace a defective one. We use it in a savio skimmer and pull it if it will rain enough to overflow the pond to be safe. That's maybe 2x/year. They're spendy, but to us, cheaper over time. We had cheap replacement ballast and bulb, they lasted 30 days. So we just replaced the savio ballast and got a savio bulb. I highly recommend this brand! More up front, but cheaper per year!
