half white coated halogen infrared heating lamp

May 7, 2026

We built this half-white-coated halogen infrared lamp for engineers who need pinpoint heat—without getting blasted by the harsh glare of an open filament. It’s a shortwave infrared emitter, made to jump to temperature fast and aim that heat right where you need it.

Here’s what makes it tick

This thing packs serious power into a small footprint. It typically runs at 400V, pulling strong current to generate intense heat from a short tube. That tight concentration means you can heat small zones almost instantly—but it also means your electrical setup needs to be up to the task. And don’t forget the cooling. Your machine’s cooling system has to be properly sized to handle the extra heat. If it’s not, the lamp and its electronics will start running way too hot.

The guts of the design

Inside, you’ve got a quartz envelope around a halogen filament. The halogen cycle keeps the filament clean at high temps, which helps the lamp last longer and keeps output steady. The half-white coating? It’s not just for looks. It reflects infrared forward while shielding your eyes from direct visible light. And the R7s double-ended connector gives you a solid, high-temp connection that handles the quartz tube’s expansion without shifting or shorting out.

Why it matters on the floor

On an industrial line, you want heat where you need it—and absolutely nowhere else. That coating directs the energy, so you waste less heat and your process runs more efficiently. Plus, shortwave infrared penetrates surfaces faster than long-wave options, so cycle times move quicker. It drops straight into existing fixtures, making it a simple upgrade for lines doing PET preform heating, thermoforming, or adhesive curing. Expect rapid ramp-up, steady output, and a rugged build that keeps performing—cycle after cycle.
