Meet the R7s tungsten halogen lamp. It’s the kind of workhorse you want when you’re squeezed for space but still need serious, focused infrared heat. We built these for the moments when you need power on demand, right where you need it.
The Specs, Straight Up
These lamps come in 230V or 400V, with wattages that run from 1000W to 2500W. You can pick a tube length anywhere from 300mm to 1180mm, so you can match the heat zone to your machine without overthinking it. Go for the 400V version and you get a nice bonus: lower current draw. That means you can use thinner wires and take the strain off the socket. It’s a small detail that makes a big difference in the long run. Packing all that power into a short tube means you get a serious heat punch. The ramp-up is fast—really fast. But that also means you need to plan for cooling. Keep the enclosure happy and the whole system stays stable.
What’s Inside Matters
We chose a quartz envelope because it handles the shock of turning on and off, again and again. No drama. The tungsten halogen cycle keeps the filament clean, which helps the lamp live longer and stay consistent. And if you need the heat to hit just right, many versions come with a coating that pushes the output into the shortwave infrared band. That’s the sweet spot for plastics and coatings—they soak it up fast. And the R7s double-ended connector? It’s simple, solid, and makes the lamp a drop-in replacement. Hook it up, line it up, and you’re good to go.
Where It Shines
These lamps are your go-to for jobs like plastic forming, sealing, and drying—anything that needs fast, controllable heat in a tight spot. The infrared output hits the target directly, so you get immediate response and skip the long warm-up. Just keep one thing in mind: the heat density is high. Plan your shielding and airflow so nearby components stay protected, and your control stays steady.
