We built the 500mm Halogen Infrared Lamp for those tight spots where you need serious heat, right now. It’s a shortwave infrared emitter, designed to put the heat exactly where you want it—fast, focused, and direct. Power and size, in a nutshell It packs 400W into a 500mm length, so the watt density is high. That means you get a tight, concentrated heat zone that brings surfaces up to temperature in a hurry. Just make sure your voltage is steady—mismatched voltage pushes the filament too hard and shortens its life. And the 500mm length? It gives you a long, even heating window without having to rework your whole setup. What it’s made of, and why it matters The core lives inside a quartz envelope, chosen because it handles sudden temperature swings without cracking. Inside, the halogen cycle keeps the filament stable by putting evaporated tungsten back where it belongs, which helps the lamp last longer. The shortwave output is tuned to be absorbed quickly by many materials, so more of the heat goes into your work—not into warming the air around it. And the R7s base? It’s a secure, two-point fit, so swapping it into your existing fixtures is straightforward. Where it shines, and what to keep in mind This lamp is the kind of choice you make when fast, localized heating is the key to keeping cycle times moving—think plastic welding, coating curing, and drying parts. It’s compact, so it slots in easily, and the focused heat profile means less wasted energy. But here’s the thing: that high heat density means your fixture needs proper ventilation and thermal shielding. Keep airflow and clearance as specified, and it will keep performing reliably, even on sustained duty cycles.
