Let’s talk about the 620mm 2000W halogen Lamp
When we built this short-wave infrared (SWIR) lamp, we weren’t looking for a “gentle warm.” We were looking for raw power. With 2000W packed into a 620mm frame, this thing hits your target temperatures in seconds. It’s fast. Really fast. And for processes that can’t afford to wait around, that’s exactly what you need. The secret to the heat Here’s the thing: when you’re pushing this much energy, the tungsten filament wants to evaporate and cloud up the glass. To stop that, we use a halogen cycle. It keeps the quartz tube crystal clear, which means the lamp lasts longer and keeps performing. Since the 620mm size is a standard for PET blowing machines and industrial drying tunnels, it usually drops right in. Just a heads-up: keep your reflectors clean and lined up, or you’ll lose that consistent heat spread. Getting it wired up We used a high-grade quartz envelope because, frankly, anything else would warp under this kind of stress. We also stuck with standard industrial connectors so you aren’t fighting with the wiring. But wait—check your power supply first. 2000W is a lot of juice. If your system isn’t ready for that peak load, you’re going to be tripping breakers or frying your contactors. It’s a pain to fix, so just double-check your current draw before you flip the switch. Where it works (and where to be careful) These are the go-to for curing coatings, drying inks, or getting plastics pre-heated. The short-wave radiation just sinks right into the material. But there’s a catch. All that heat doesn’t just go into your product—it beats up the housing, too. You can’t just tuck these into a sealed box and hope for the best. You need forced air cooling or some heavy-duty heat sinks. If the air around the ends of the lamp gets too hot, the quartz will fail. Simple as that. So, make sure those cooling fans are screaming before you power everything up.
