870mm 2500w paint infrared heat lamp halogen bulb

May 6, 2026

Introduction

Here’s the thing: we built the 870mm, 2500W halogen infrared heat lamp to be a straight-up workhorse for industrial finishing and curing lines. It’s all about direct, powerful heat—exactly where you need it, when you need it. We packed serious power into a compact size, so it slips right into your existing fixtures. It’s not just a lamp; it’s a focused blast of heat designed for processes where speed and temperature control are everything.

Power, Voltage, and Geometry—Why It All Matters

That 2500W rating isn’t just a number. It’s what gives you that rapid heat-up on moving parts, like wet paint or coated materials. The 870mm length is another deliberate choice. It gives you a wide, even heating zone, so you don’t need a bunch of lamps crammed together. That means fewer hot spots and a smoother line speed. And the voltage? It’s all about matching your setup. You choose the voltage that fits your plant—230V or 400V—so the electrical draw lines up with your machine’s wiring. For example, at 400V, the current is lower than at 230V, which takes the strain off your terminals and switchgear. But, you still need to size your cooling and electrical drops right. High power density means the enclosure and reflector have to shed heat effectively, so you don’t cook the components nearby.

The Heart of the Lamp: Halogen, Quartz, and a Simple Base

Inside, the lamp runs on a halogen cycle, all sealed in a high-purity quartz envelope. Quartz is tough—it handles the shock of rapid on/off cycles and stays crystal clear for that short-wave infrared heat. The halogen cycle keeps the filament clean by putting the evaporated tungsten right back where it belongs. The result? Stable output and a longer life than your standard incandescent bulb. Then there’s the R7s base. It’s the standard for double-ended linear halogen lamps, and for good reason. It gives you a solid, aligned connection that can handle the vibration of a busy shop floor. Installation? Just slide the lamp into the ceramic socket, give it a twist to lock, and you’re wired up. That linear shape and R7s base make it a direct drop-in replacement for many existing heating setups, which means less downtime.

Where It Shines: Real-World Results

When you’re curing paint, that short-wave infrared heat gets right into the surface. It drives off solvents and cross-links the coating fast, without scorching the material underneath. You end up with faster line speeds and using less energy per part. And for drying or pre-heating, you can focus that heat exactly where you need it. That kind of precision boosts your efficiency and cuts down on waste. We built this lamp for the real World—the heat, the constant vibration, the long hours. It gives you a predictable heating profile, integrates easily, and can take a real beating. When your process needs fast, focused infrared heat, this is the lamp that delivers, again and again.
