High intensity mercury UV tube

We built this high-intensity mercury UV tube for one reason: to give you heat that hits hard—and hits exactly where you need it. This isn’t a “do-it-all” lamp. It’s a focused thermal tool, born for industrial heating, curing, and material work—jobs where speed on the ramp-up and steady output aren’t optional. Power, voltage, and size—kept tight for a reason. These tubes run on high-intensity discharge physics, packing a lot of radiant energy into a small footprint. The 400V operating voltage keeps the arc steady, which helps prevent output drift from current ripple. At 300mm long, the heating zone stays concentrated. And the 2500W rating? That’s the muscle behind the heat density, so setpoints come fast. It’s fast. Really fast. You’ll feel that in the rhythm of your process. But with that kind of power density, you’ve got to plan for cooling. The surrounding hardware needs to manage the heat—otherwise you’re inviting nuisance trips and pushing components to wear out early. What it’s made of—and why it matters in the real world. The heart is a quartz envelope, chosen because it can handle thermal shock and still transmit UV strongly. A halogen fill keeps the arc stable and helps keep the quartz clean during operation, so output stays consistent over time. Inside, mercury vapor delivers the high-intensity radiation profile that makes rapid heating possible. And the R7s bi-pin connector? Practical choice. It locks in, carries the current, and makes replacement quick—just pop it in on compatible fixtures. How it feels when you’re running production. This setup is built for repeatability. Predictable heat. Consistent cycle times. Maintenance that doesn’t turn into a project. You’ll see it shine in jobs like plastic welding, coating curing, and component drying—places where the process window is narrow and you can’t afford surprises. The intensity is high, the voltage operation is stable, and the length stays compact, so you can steer the thermal profile without overhauling the whole machine. Just make sure your cooling and fixture clearance are dialed in—then the tube does the rest.
