We built this 400V, 2500W halogen infrared heater for the places that need serious, dependable heat—industrial spaces, process work, the kind of environments where warmth isn’t a luxury, it’s part of the job. If you’re an engineer, you know the drill. You want predictable watt density, output that stays steady, and a component that slides right in without forcing you to redesign the whole fixture. That’s exactly what this is for.
Why it works the way it does
The 400V rating isn’t random. It matches up with industrial power lines, which keeps the current lower than you’d get with a 230V setup at the same wattage. That means less voltage drop on longer runs, and wiring and contactors that stay comfortably within their limits. The 2500W rating packs a lot of heat into a small footprint. So it heats up fast—like, immediately—when your control system says it’s time to go. And the 300mm tube length? It’s a sweet spot. Long enough to spread the warmth evenly, short enough to fit snug spaces without feeling flimsy.
The stuff that makes it last
Inside, the halogen chemistry keeps the filament from evaporating, which helps the lamp hold its output over time. The quartz tube can handle rapid heating and cooling without cracking, and the reflector coating pushes the energy forward instead of letting it spill out the sides. Then there’s the R7s base—a no-nonsense industrial connector that locks the lamp in place, carries current reliably, and makes swapping it out a quick, simple job.
Where it shines
This heater is your go-to for fast, focused infrared heat in workshops, drying stations, and equipment enclosures. The 400V power, compact 300mm size, and halogen stability give you heat you can count on, over and over, with hardly any fuss. Just keep one thing in mind: that high watt density means you need solid ventilation and a bit of thermal planning around the fixture. You don’t want nearby components getting too hot.
