What These Infrared Heaters Are Really Built For

We built these infrared heat lamps for engineers who need heat that’s direct, easy to control, and doesn’t take up a ton of space. At the heart of it is a 300mm halogen bulb, usually set up for 400V and 2500W. That kind of power isn’t random. It’s about getting intense heat exactly where you need it, fast. If your process depends on ramping up temperature quickly, this is the kind of punch that gets the job done. And the 400V rating? That’s a practical choice. It’s meant to plug straight into standard industrial power, so you don’t have to mess around with extra transformers.

The Pieces That Make It Work: Halogen, Coating, and the R7s

Inside the quartz envelope, the halogen element does the heavy lifting. It delivers a steady shortwave infrared output that cuts right into materials. The quartz tube is often coated, and that coating isn’t just for looks. It helps shape the emission spectrum so the energy hits the right absorption bands—especially for materials like plastics or coatings. It protects the filament and steers the heat where it matters most. Then there’s the R7s connector. It’s the standard for a reason. This bi-pin end-cap gives you a secure, high-temp electrical connection that can take the heat at the ends of the lamp without melting or losing contact.

How It Fits In: Real-World Use and Setup

These lamps are the backbone of heating zones in manufacturing—think PET blowing lines or thermoforming setups. The 2500W output gives you the heat flux you need, but here’s the trade-off: packing that much power into a 300mm tube creates serious localized heat. So your machine’s cooling system needs to be set up to handle the temperature rise around it. We include a rheostat for analog control, which means you can dial in the exact temperature profile you want. That makes this lamp a straightforward, drop-in replacement for existing halogen systems—so you can get it installed and keep downtime on the line to a minimum.
