What Makes These Lamps Tick
When we’re sizing up lamps for big water treatment setups, it’s all about the physics. You need serious power, but you can’t afford to waste space. So these run at 400V and crank out up to 2500W. That’s what it takes to hit a UV dose that actually knocks out pathogens, even when the water is flowing fast. And that 300mm length? It’s a sweet spot we landed on. Long enough to give the arc a stable path and plenty of surface to radiate, but still short enough to fit neatly into tight manifolds. No fuss, no oversized footprint—just right.
The Build, Inside and Out
At the heart of it is a shortwave halogen lamp, wrapped in a quartz envelope. This stuff is tough—it handles sudden temperature shifts and lets the UV pass through cleanly. The halogen inside keeps the filament steady and fights off the blackening that kills performance over time. We also added a specialized coating on the quartz to stand up to hard water scaling and harsh chemicals. So output stays steady, even when conditions get rough. And the R7s connector? It’s a simple two-pin setup. Wiring is straightforward, and swapping a lamp in the field is quick. No tools needed. Seriously.
Real-World Performance
These lamps live in large treatment plants, where they run nonstop. The 400V, 2500W setup gives you a lot of heat in a small space, so you do need to make sure your cooling and sleeve flow are on point. Keep that right, and you avoid overheating and early failures. The whole design is meant to drop right in. If your system already needs reliable disinfection, you don’t have to tear things apart to make it work. Expect consistent output, hour after hour, for thousands of hours—as long as the water chemistry and flow stay within the design limits. That’s the kind of steady you can count on.
