500mm 400v 1200w Halogen Lamp Replacement Parts

May 14, 2026

Introduction

We built this 500mm, 400V, 1200W halogen lamp to be a straight-up, no-nonsense replacement for industrial heating setups. It was designed for machines that need heat fast, keep it steady, and fit right into what you already have. No fuss, no modifications—just a clean swap.

Power, Voltage, and Size: What It Means on the Floor

The 1200W rating is all about the heat you get—the kind that gets the job done. And the 500mm length? That sets the shape of your hot zone. Running at 400V instead of 230V drops the current for the same power. That matters. Lower current means less energy lost in the wiring and less voltage drop over long runs. In real plant conditions, that helps keep the element temperature steady, so your heat stays consistent where it counts. The 500mm size also makes your life easier. You get a long, even hot zone in one piece, so you don’t have to stack shorter heaters. Fewer pieces to manage. Fewer connection points. Cleaner control.

What’s Inside: Halogen, Quartz, and a Connector That Just Works

Inside, you’ve got a tungsten-halogen element in a high-purity quartz tube. The halogen cycle keeps the filament from blackening the tube, so the lamp holds steady output over its life. The quartz handles thermal shock and runs hot enough to keep the element clean, which helps keep performance consistent. The connector is an R7s, double-ended, ceramic-based. We chose it because it stays stable at high temps and mounts cleanly. It’s a direct mechanical and electrical match for standard halogen sockets, so you can swap it in without changing the fixture.

Where It Shines—And the Trade-Off You Should Know

This configuration is for the moments when you need intense, localized heat, fast—think plastic processing, forming, and other industrial heating tasks. The lamp comes alive quickly and gives you tight control over heat, so you can hold repeatable temperatures on your parts. Here’s the trade-off: packing 1200W into a 500mm tube means high heat density. So your machine needs good airflow and shielding to keep nearby components from getting too hot. Plan for that, and this lamp performs like it’s meant to—dependable, direct, and ready.
