400V 2500W Infrared Halogen Heater: Big Heat, Small Package

We built this 400V, 2500W infrared halogen heater for the moments when you’re squeezed for space but still need heat—fast. It’s a shortwave lamp that throws a concentrated punch in a compact body, perfect for spot heating and getting things hot quickly.

Power, Voltage, and Size—Why It Matters

That 2500W at 400V wasn’t chosen by accident. Running at higher voltage means less current for the same power, which lets you use thinner wires and cuts down on voltage drop over distance. In practice, that makes wiring easier and the heater less sensitive to how long your feeder lines are. And the size? It’s typically a 300mm tube, so it slips into tight spots without fuss. That high watt density delivers intense heat right where you need it. But here’s the catch: that same intensity means the surrounding equipment has to handle extra heat. Plan your cooling and shielding before you flip it on.

What’s Inside: Halogen, Quartz, and a Simple Connection

Inside, the halogen cycle keeps the filament stable and helps extend the lamp’s life by putting evaporated tungsten back where it belongs. The quartz envelope can take the heat and lets shortwave infrared pass through efficiently. The R7s connector is a no-brainer—industry-standard, solid contact, and it slips right into many existing fixtures. And the reflector coating? It focuses the energy forward, so more heat lands on the target and less gets wasted.

In Real Life: Fast, Focused Heat

This setup shines when you need rapid, localized heating—think plastic forming, sealing, or curing. The shortwave output responds quickly, and the high power density lets you bring small zones up to temperature in no time. You get heat that’s predictable, output that stays steady over the life of the lamp, and a design that’s tough enough to handle repeated heating cycles. Just keep one thing in mind: with this much heat packed into a small space, you’ll want a cooling and mounting setup that’s up to the job, so the rest of your gear doesn’t cook.
