Let’s talk about the 495mm 2500W Halogen Lamp

If you’re dealing with high-density thermal loads—think industrial curing or plastic forming—you know that waiting for a machine to warm up is a total productivity killer. That’s why we built these 495mm halogen elements. They’re designed to hit those high temperatures fast. The power side of things We’ve set these at 400V to push 2500W through the tube without blowing a fuse or overloading your current. It gives you a really concentrated heat footprint, which is great for keeping your cycle times tight. But a quick heads-up: if you’re swapping these into an old rig, double-check your transformers. A 400V draw gets hot—really hot—at the terminals. Make sure your wiring can actually handle the load, or you’re looking at a burnout. Why the “half-white” coating? You’ll notice a selective quartz coating on these. We call it “half-white.” Basically, it bounces some of that infrared spectrum back into the filament instead of letting it leak out. The result? The surface gets hotter and the heat goes exactly where you want it, rather than just heating up the rest of your machine housing. Plus, the halogen gas cycle stops the tungsten filament from evaporating too quickly. It keeps the tube clear and helps the lamp last a lot longer. Getting them installed These are pretty much plug-and-play for PET blowing and shrink-wrapping lines. While the 495mm length is a standard fit, 2500W is a lot of power. You’ll love how fast they ramp up, but that puts a bit more stress on the quartz. Here is the most important part:keep the glass clean. I can’t stress this enough. If you leave a fingerprint or a smudge of oil on the tube during installation, it creates a hot spot. That’s how you get a cracked tube. Just be careful with the handling and make sure your cooling fans are up to the task of handling the extra heat around the lamp bank.
