Review on 🔧 S463RL - STERILIGHT S5Q PA S5Q Gold Replacement by Donald Cummings

Three notes. The lamp I received had droplets of mercury in the tube which I had never seen before. Mercury fumes fall off naturally, I doubt it. Second, there are two opaque plastic strips on the outside of the bottle that run the full length of the tube from cap to cap and a ring in the center of the bottle as if holding these strips on the tube. Why? The problem with the stripes and the ring is that they prevent the UV radiation from getting into the water on the way: they create a shadow. Think about it. Attention is drawn to the fact that solids are filtered out of the water and that the quartz sleeve is clean to avoid shadows. Here is a lightbulb with a built-in shadow generator. Third, the image on the side clearly shows the "R-CAN" printed on the lamp. These are not R-CAN bulbs. In conclusion, I would like to note that the reviewers of these types of lamps say that these lamps work. How do they know what the intensity of the UV light they are generating is? Some say it can be called ballast. No! The ballast has a timer that counts down a year and can also detect if there is an electrical connection. OK. Lamps need to be replaced once a year or, depending on who you're reading, between 9,000 and 12,000 hours of use. Why 9000-12000 or why a year.? As the time is an approximate average based on actual testing of the intensity of UV radiation emitted by the lamp. This cannot be determined with the ballast. Drops of mercury and streaks that cast shadows on the flask are telltale signs to me of dubious quality and effectiveness. The designation R-CAN is misleading. I sent the bulbs back because I absolutely need to be sure my drinking water is adequately disinfected.
