R7S Medium Short Wave Infrared Halogen Lamps: Power, Precision, and Process Control

We built the R7S medium short wave infrared halogen lamp to be one thing: a focused heat source that gets straight to work. You need heat that turns on fast and hits hard, without taking up a ton of space. That’s exactly what this lamp brings to the table. It’s the kind of tool you lean on when the job is simple: heat the target quickly, and don’t waste energy warming the air around it.

Power, Voltage, and Size—Without the Overkill

These lamps are all about packing serious heat into a tidy package. A typical unit runs at 400V and 2500W, and it does it from a 300mm tube. The medium length gives you a clean, defined heating zone—no more reaching than you need, no more bulk than necessary. That high-voltage setup also lets us keep the filament compact. In practice, that means the heat ramps up fast, and your thermal profile stays tight and predictable.

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

The short wave output comes from a halogen cycle inside a high-purity quartz envelope. That halogen cycle keeps the filament clean, even when things run hot. So you get steady output, and the lamp lasts longer. The quartz envelope handles thermal shock, too. Switch the lamp on and off repeatedly? No drama. It’s built to take the cycling. And the R7S connector is a straight, double-ended bayonet. It’s a standard industrial interface, so you can swap it in as a drop-in replacement for existing fixtures. No redesign needed.

Real-World Use: Where Space Is Tight and Timing Is Everything

You wire this lamp into machines where space is at a premium and cycle time can’t afford to slip. It’s commonly used in PET blowing and plastic forming—jobs where you need rapid, localized heating to soften material fast. Because the lamp heats the target directly, preheat time drops and repeatability improves. But here’s the part you plan for: this is high heat density. A 2500W lamp runs hot. So you have to manage the fixture and cooling carefully to keep nearby electronics and components in a safe temperature range.
