What this bulb is really built for
We built this infrared carbon fiber heat bulb for engineers who need serious heat—packed into a small space. It runs at 400V and 2500W, and it’s just 300mm long. That means you get a fast temperature ramp, right where you need it. No heating up the whole room. Just intense, focused warmth.
How it holds up under pressure
Inside, the carbon fiber filament sits in a quartz envelope. That’s there because it can handle the shock of rapid on/off cycles without cracking. Halogen gas protects the filament, so the bulb lasts longer and keeps output steady. And the R7s two-pin connector? It’s a simple, direct fit. You can drop it straight into many industrial fixtures—just wire it up and lock it in.
Where it shines—and what to watch for
This bulb is a natural fit for PET blowing, plastic welding, and curing lines. If your work depends on fast response and stable heat, this delivers. The short-wave infrared profile gives you precise control over surface heating, so your cycles stay consistent. But here’s the thing: packing 2500W into a 300mm tube means serious power density. You need proper cooling and thermal shielding. Plan your heat management up front, or the enclosure will get too hot.
