4kW Quartz Tungsten Halogen Heat Lamps: The Industrial Heat You Can Count On

We built the 4kW quartz tungsten halogen heat lamp for one simple reason: to give you serious infrared heat, in a package that doesn’t eat up your floor space. It’s for the moments when you need heat—fast—and you need it to be controllable. Think plastic forming, curing coatings, or drying parts. Places where you’re squeezed for room, but you can’t afford to wait around.

Power, Voltage, and the Size That Fits

Let’s start with the power. The 4kW rating isn’t just a number; it means you get a lot of heat without needing a giant setup. But that power also needs a steady electrical feed. That’s why we set these lamps up for 400V operation. It keeps the current manageable, so your wiring and connections stay safe and practical. And the size? The lamp is usually around 300mm long. That gives you enough surface area to spread the heat evenly, while still fitting into those tight, crowded machine bays. Pair it with the right reflector and mounting hardware, and you get a predictable, focused hot zone exactly where you need it.

What’s Inside: The Design That Works

The envelope is made of quartz, which handles the extreme heat and stays clear enough to let that infrared energy pass through efficiently. Inside, the tungsten filament runs hot—really hot. But the halogen cycle is the quiet hero here. It catches the evaporated tungsten and sends it back to the filament, which keeps the lamp from getting that dark, burnt look over time. The result? Consistent heat output, for the long haul. And for the connection? We use an R7s base. It’s simple, solid, and gives you two points of contact. It’s a common, serviceable choice in industrial heating setups, and it makes replacement straightforward when you’re out on the floor.

Built for the Real World

On a production line, you need heat that responds instantly and holds steady. These lamps deliver. They get hot fast, so you can keep your cycles moving and maintain a consistent temperature, every single time. The compact size is a lifesaver in tight spots, and the halogen design keeps the output stable as the lamp ages. Here’s the thing: packing 4kW into a small tube creates serious heat density. That means your fixture needs to be set up right—with proper airflow and shielding. But get the cooling and reflector setup dialed in, and you’ve got heat you can rely on. Heat that keeps your line moving, no excuses.
