400v 3500w infrared halogen heating lamp

June 3, 2026

We built this 400V, 3500W infrared halogen lamp for one reason: to get heat where you need it, fast—especially when space is tight and the clock is ticking. It’s the kind of direct-heat solution you lean on when you’re forming plastic, curing coatings, or testing components, and you can’t afford to wait around. The heat is focused. The footprint is small. And the response is almost immediate.

Power, voltage, and output—kept simple

At 3500W, this lamp delivers serious heat density. It warms up quickly and holds steady in those localized zones that demand precision. We chose 400V because it lowers the current draw compared to lower-voltage options. That means less line loss and wiring that’s easier to manage inside industrial panels. So you can spec this heater into your system without having to oversize cables and contactors. And the 300mm tube length? That concentrates the heat into a tight footprint, so it slips into cramped machine bays without a fight.

Materials and design that do the job

Inside the quartz envelope, the halogen element keeps output consistent over time. It regenerates the filament, so you don’t get the blackening that would otherwise dim performance. The shortwave infrared profile means energy transfers straight into the target—quickly and directly—so less heat goes to waste in the surrounding air. And the R7s bi-pin connector? It’s straightforward and secure. You get a drop-in fit into existing fixtures, with no fuss.

Where it shines—and what to watch for

This setup is at its best when you need rapid, focused heat with minimal warm-up. You’ll see it used for PET preheating, thermoforming, and adhesive curing. Here’s the trade-off: that high heat density needs proper airflow and thermal management. Keeping ambient temperatures in check matters. So you’ll want to get the mounting distance right and align the reflector properly. That’s how you hit the target temperature without cooking nearby components.
