Introduction
We built this carbon glass heating lamp for one reason and one reason only: to get you raw, focused heat when your standard heater just throws in the towel. This isn’t some all-purpose bulb. It’s a beast of a radiant heat source, designed for industrial work where you need temperature to climb fast—and stay exactly where you want it. When you need heat that cuts straight to the core, this is the tool you build into the machine.
The Power, The Fit, The Specs
Let’s talk numbers, but the kind that actually matter. A typical unit runs at 400V and 2500W. That’s intentional. It lets us pack a lot of power into a long 300mm tube without overloading your wiring. The payoff? A huge amount of heat in a small space. That 300mm length gives you a clear, defined heating zone. Match the lamp to the spot you’re heating, and you’re not wasting energy on empty air.
What It’s Made Of, and Why It Matters
The tube is quartz, not regular glass. Why? Because quartz can handle the shock of going from cold to scorching over and over again, and it stays rock-solid even when things get extreme. Inside, the carbon element keeps resistance steady, so the output stays predictable over the life of the lamp. We also coat the quartz to tune the heat spectrum, focusing the energy on the wavelength your material absorbs best. And the R7s connector? It’s just practical. It handles the high current, makes end-to-end wiring clean, and lets you drop it in without rewiring the whole fixture.
Where It Shines—and What To Keep In Mind
This lamp really comes alive in jobs like PET blowing and plastic welding, where you need heat on demand. The radiant heat hits the surface directly, so you get to working temperature fast. But here’s the trade-off: that kind of power means your machine’s cooling has to be up to the job. If the cooling isn’t right, the surrounding parts will bake. Get the size right, wire it with the proper terminations, and you’ll have a heat profile you can count on—one that keeps the line moving without guesswork.
