Shortwave Clear 300mm 500w Infrared Halogen Heater Parts

Let’s talk about 300mm 500W Shortwave Halogen Heaters

If you’re looking for heat that hits now—not in five minutes, but right this second—these 300mm shortwave lamps are your best bet. We built them for those specific jobs where you can’t afford any lag. The 500W power spread across that 300mm length is a sweet spot. It gives you a punchy, rapid surface heat without burning through the filament too quickly. Why shortwave? Basically, the energy just moves faster. It penetrates your material almost instantly. To make sure nothing gets in the way, we use clear quartz envelopes. Some people use coated tubes, but that shifts the spectrum. We stick with clear glass so the full force of that shortwave energy actually hits your workpiece. The secret sauce inside We use a halogen gas fill to keep things running smooth. Here’s the deal: as the tungsten evaporates, the halogen cycle pushes it right back onto the filament. It stops the wire from thinning out, which means your heat output stays steady instead of dipping over time. Most of these come with R7s or similar slide-in connectors. They’re designed to be a simple drop-in replacement for most industrial banks. One quick tip:**keep your sockets clean.**If you’ve got oxidation on the contacts, you’ll get hotspots. And trust me, you don’t want to be the person who accidentally melts their own housing. Where this actually works These are perfect for “flash” heating—think PET blowing, curing paint, or welding plastics. But a heads-up: these things are intense. They put out a lot of visible light and a ton of heat. Make sure your team has the right PPE and shielding so nobody is staring directly into the UV and IR rays. Also, keep an eye on your materials. Darker colors soak up this energy way faster than reflective or light-colored surfaces. Just something to keep in mind when you’re dialing in your timing.
