SK15 head carbon fiber

May 3, 2026

Introduction

Picture this: you’ve got a heating job that needs power—real power—but space is at a premium. That’s exactly why we built the SK15 head carbon filament halogen lamp. It’s not the kind of heater you’d use to warm a room. This is a focused, industrial beast. It’s all about getting intense heat, fast, right where you need it. Think of it as the precision tool for machines where speed and a small footprint are everything.

The Power Behind the Design

Let’s get into the guts of it. The SK15 is built with a compact, linear shape, usually running between 150 and 300 mm long, depending on the wattage. We run these on high voltage—typically 400V—and here’s why that’s smart. It keeps the current low, especially when you’re packing several lamps close together. Lower current means you can use thinner wiring, simpler insulation, and you won’t get that frustrating voltage drop over long runs inside your machine. And when we pick a wattage, it’s never about hitting some flashy marketing number. It’s about delivering the exact heat flux your process needs. A 2500W lamp in a short body gives you a huge punch of heat per inch. That’s perfect when you’re heating a narrow zone—like for preform heating, sealing bars, or localized curing. But there’s a trade-off. That kind of power density demands respect. You have to manage the heat properly. If you’re pushing it hard, the reflector and airflow have to be designed to keep the lamp and nearby parts from overheating.

What Makes It So Tough?

We chose carbon filaments in a halogen environment for a reason. They deliver stable infrared output and last a long time, even with the constant on-off cycling you see in factories. That halogen cycle is the secret sauce. It stops the glass from blackening by putting the evaporated material back onto the filament. So the output stays consistent, hour after hour, for thousands of hours. The quartz envelope can handle extreme heat and the kind of vibration and thermal shock that would break a lesser lamp. And the SK15 end-cap? That’s pure industrial practicality. It gives you a rock-solid mount and a reliable electrical connection, so the lamp stays perfectly aligned in its reflector. No arcing. No drifting, even when the machine is shaking.

Where This Lamp Really Shines

This design really earns its keep in plastic processing. If you’re doing PET blowing or preform heating, you know how crucial fast, localized heat is. The SK15 gives you that, with precise control over the heated zone. Its shortwave response means it can change temperature almost instantly, keeping pace with high-speed cycles. For you, that translates to predictable heating and a simple retrofit. The lamp is designed as a direct drop-in replacement, so you can swap it out quickly and get back to work. The stable output from the carbon/halogen mix, combined with the secure SK15 termination, means you can trust it to stay put, even when things get hot and shaky. Just keep one thing in mind: managing that heat load is key. You get incredible speed, but that also means more ambient heat in the machine. Plan your cooling and shielding up front, and you’ll be golden.
