Hot selling 420mm 220vac 1500w halogen bulb short wave electric heater parts

May 6, 2026

Introduction

We built this shortwave halogen bulb to be the heartbeat of your industrial heating system. It’s a direct-fit, 420mm heater element, running on 220VAC and cranking out 1500W of focused heat. If you’re an engineer, you know the drill. You need something that just works—predictable heat, a compact fit, and zero drama when you’re integrating it into a machine. That’s what we set out to deliver.

The Nitty-Gritty: Power, Voltage, and Size

Let’s get into the numbers, but keep it real. The 1500W rating at 220VAC means you’re getting a solid, stable load that’s a breeze to spec out for your standard control panels. And that 420mm length? It’s not a random choice. It’s all about nailing the heated zone geometry, so you can perfectly match the focal distance in focused-heat setups. Shortwave means the filament runs hot, which gives you intense radiant heat that kicks in fast. But here’s the thing—that kind of wattage density comes with a catch. It demands proper heat management. If your reflector or enclosure is too small, you’ll push component temperatures too high and shorten the bulb’s life. So, do yourself a favor and plan your airflow and clearances before you even think about wiring it up.

What’s Inside: Halogen, Quartz, and the Right Fit

Inside, the halogen cycle is the unsung hero. It keeps the quartz envelope cleaner by sending tungsten back to the filament. This keeps the light output stable and cuts down on blackening over time. And the quartz tube itself? It’s tough. It handles the searing filament temperatures and shrugs off thermal shock, even when you’re power-cycling quickly. For the install, we went with an R7s-type double-ended base. It gives you a rock-solid mechanical hold and perfect alignment. You just drop the lamp into the reflector assembly—no wiggle, no bad contacts. On the shop floor, that means fewer alignment headaches, fewer hot spots, and a lot fewer service calls.

Why It Works: Built for Real-World Heat

This setup is the go-to for industrial processes that need concentrated radiant heat and a lightning-fast start-up. Think plastics heating, drying components, or any localized heating job where you need a ton of heat in a small space. The shortwave spectrum delivers energy that materials just soak up, making heat transfer way more efficient right where you need it. The 420mm size slides perfectly into tight reflector assemblies, and the 220V 1500W rating makes sourcing parts simple. You get fast warm-up, rock-solid output, and a seriously tough element. Just make sure your machine’s cooling and mounting are up to the task of handling all that concentrated power.
