Commercial Radiant Halogen Heater: 400V 2500W Tube with R7s Connector
We built this heater for the places where you need serious heat, but you don’t have room to spread out. Think industrial work zones where space is tight and the heat has to show up fast. It’s a halogen-filled quartz tube, running at 2500W on 400V. That voltage choice isn’t random. It keeps the current lower, so you can run smaller wiring and lose less voltage over distance compared to 230V options.
Power, voltage, and the fit
Here’s the thing about 2500W on 400V: you get a lot of heat density without making the current scream. That means the heater warms up quickly and throws a tight, focused hot zone. Exactly what you want when the job calls for pinpoint heating. And the tube length is sized to sit neatly inside compact reflector setups, so the heat goes where you aim it—no wasted spread.
The build: halogen, quartz, and the R7s base
Inside, the halogen cycle does the quiet work of keeping the filament steady. It catches evaporated tungsten and puts it back where it belongs, so performance stays consistent. The quartz envelope handles the shock of rapid on/off cycling, and stays clear enough that the radiation output doesn’t drift. Then there’s the R7s connector—straight, double-ended, ceramic. It locks in fast and can take the heat at the tube ends without blinking. And because it’s a standard interface, it drops straight into many existing fixtures. No drama.
Where it shines—and what to keep in mind
This setup is for commercial heating where you need radiant heat on demand, repeatable results, and a replacement that’s easy to handle. But with 2500W packed into a compact tube, you’re dealing with serious heat density. The fixture around it and nearby components will feel that heat, so plan for airflow and shielding. Do that, and you’ve got a heater that hits hard, heats fast, and stays reliable when the work is relentless.
