Picking the Right Halogen Infrared Lamp: 300W to 2000W

If you need a serious heat source, these halogen infrared lamps are your best bet. They basically use a tungsten filament inside a quartz tube filled with halogen gas to crank out high-intensity heat. We carry everything from 300W up to 2000W, so you can pick the one that actually fits your project. Picking your power The choice between 300W, 500W, 1000W, or 2000W really comes down to how much heat you need hitting your workpiece every second. Think of it this way: a 300W lamp is like a gentle soak. It’s steady and soft. But a 2000W tube? That’s an aggressive thermal punch. It hits hard and fast. Just a heads-up on the electrical side. More wattage means more current. You’ve got to make sure your wiring and relays can actually handle the amperage. If you try to push 2000W through a circuit built for 500W, you’re going to fry your contacts. Not a fun way to spend a Tuesday. The build and the fit We use high-purity quartz for the envelopes. Why? Because standard glass would just warp or melt under this kind of heat. Plus, the halogen cycle keeps the tungsten moving back onto the filament, which means these last way longer than the old-school light bulbs you’d find in a closet. When it comes to getting them installed, we usually stick with R7s or SK15 connectors. They’re designed to slide right into most industrial heating banks. They fit tight, which is exactly what you want—it keeps the electricity flowing smoothly and stops those nasty arcs from jumping at the terminals. Real-world use (and the catch) You’ll see these all over the place—PET blowing, curing paint, welding plastics. The best part is the speed. You can hit your target temperature in seconds. No more standing around waiting for a machine to warm up. But here’s the thing. These high-wattage lamps put off a ton of ambient heat. If your cooling fans aren’t doing their job, that heat is going to bleed back into the lamp housing. Before you know it, your wiring insulation starts to degrade. To keep things from failing early, just leave a bit of a gap for the air to move. Your equipment will thank you.
