Introduction
We built this 400V, 3500W infrared halogen heating lamp for engineers who need serious heat in a small space. If your project demands focused warmth, fast response, and a footprint that doesn’t take over the whole work area, this is the kind of tool you can count on.
The Details, Without the Fluff
That 400V rating? It isn’t just a number. It lets us pack 3500W of power into a compact quartz tube without overworking the electrical connections. The payoff is a lot of heat in a small package, which means you get up to temperature quickly and stay there. At 300mm long and 10mm in diameter, the lamp stays small enough to fit into tight machine cavities. But with that kind of concentrated power, you need to plan ahead. The area around it gets hot—really hot—so make sure your setup has room for airflow or a little shielding.
What It’s Made Of
Inside the quartz envelope, the halogen cycle keeps the filament stable. That means you get consistent output over thousands of hours, instead of the quick burnout you see with standard incandescent elements. The shortwave infrared output is tuned to be absorbed by many industrial materials, so more of the energy becomes usable heat, with less wasted warmth. The R7s connector is a practical, shop-floor choice. It handles high current, locks in securely, and makes installation simple—slide the lamp in and you’re set. The ceramic base and tough seals are built to handle vibration and the daily push and pull of thermal cycling.
Where It Shines
This lamp is at home wherever you need fast, focused heat—PET blowing, plastic welding, adhesive curing, coating drying. Because it’s powerful, compact, and stable, it can slide right into machines that need more thermal output without forcing a full redesign of the heating block. Just keep one thing in mind: at 3500W, it runs hot. You’ll need a power supply that’s up to the job and a cooling plan that works. Line up your wiring, mounting, and heat management from the start, and you get a heat source you can tune for repeatable, dependable results.
