Technical Specifications and Application of 400mm 800W Halogen Infrared Lamps

Getting the Most Out of Our 400mm 800W Halogen IR Lamps

If you need heat—and you need it now—this is where these lamps come in. We built these 400mm halogen infrared lamps for the kind of jobs where you can’t afford to wait around for things to warm up. At 800W, the heat is concentrated. It hits the entire 400mm length evenly, so you don’t end up with those annoying cold spots that ruin a batch.

Why the Halogen Matters

Here’s the thing: the halogen gas inside the quartz tube is the secret sauce. It lets the filament run much hotter than your average IR lamp. Because it’s hotter, the heat penetrates deeper into your materials. It’s not just surface-level warmth; it’s a fast, deep soak. You’ll notice your workpieces hitting their target temperature way quicker than before.

No More “Blackened” Glass

We use high-purity quartz because it lasts. Plus, the halogen cycle stops the filament from evaporating and gunking up the inside of the tube. You know those cheap heaters that turn black and lose their punch after a few weeks? This doesn’t do that. The glass stays clear, the light keeps flowing, and your output stays consistent.

A Few Tips for Setup

These are designed to be simple drop-in replacements for most industrial drying or curing setups. They work easily with standard controllers, but**please double-check your voltage.**If the specs don’t match, you’ll fry the filament instantly. One more thing: 800W in such a small space creates a lot of intense heat. If your reflectors are off or your housing isn’t vented, you might warp your brackets or kill a nearby sensor. Make sure your cooling fans can actually handle the heat buildup around the lamp head.

Where These Really Shine

We usually see these working hard in:

Preheating PET bottles
Shrinking plastic films
Curing industrial paint
Powder coating lines
