222mm 144v 1200w infrared tungsten heat lamp half white coated halogen heat lamps

Introduction

We built this infrared tungsten heat lamp to be a tough, direct-fit heat source for industrial machines that need fast, focused energy. At 222mm long, 144V, and 1200W, it’s designed to get the job done—no fuss. The quartz envelope has a half-white coating, and the halogen cycle keeps output steady even when the lamp gets knocked around on the shop floor. It just keeps going.

Power, Voltage, and Size—Why It Matters

We made it 222mm long and 1200W so you get serious heat density without needing a bigger tube. That means it slips into tight heating zones where space is at a premium. And the 144V rating? That wasn’t random. It’s a deliberate match for specific industrial control systems and busbar layouts. Run it at this voltage and you cut down on current draw compared to lower-voltage options, which helps keep conductor sizes and contact stress in check. If your machine was designed around this voltage and envelope length, this is a straight swap. No re-engineering, no headache.

Inside the Build: Halogen, Coating, and Tungsten

The tungsten filament runs hot, giving you shortwave infrared that ramps temperature fast. The halogen cycle keeps the filament from blackening the envelope, so both light and heat stay consistent over time. The half-white coating on the quartz tube tames glare and spreads the beam, so your heat profile lands more evenly across the target. And because it’s quartz, it handles thermal shock better than standard glass. Quick cycles, repeated starts and stops—less risk of cracking.

Where It Shines—And What to Keep in Mind

This setup is made for industrial heating where speed matters. You’ll see it spec’d into plastic processing, curing, and drying equipment that needs to heat up fast and hold steady. The compact size makes mounting simpler, and the standardized voltage makes integration cleaner. One thing to keep in mind: 1200W is dense. Make sure there’s adequate airflow or heat sinking around the socket and reflector area. Run it within the rated voltage, and you get repeatable heat with predictable maintenance intervals. On the shop floor, that kind of consistency is the kind of peace of mind you can feel.
