We built this 400V halogen heater for engineers who need serious heat in a small footprint. At its heart is a 300mm quartz tube, packing 2500W and running on 400V. The result? Focused infrared power that gets straight to work.
Power, voltage, and size—why it matters
We chose 400V and 2500W so you can push high watt density without overloading your wiring. The 300mm length concentrates all that power into a tight zone, which means fast response and a clean thermal profile. That kind of heat density lets the lamp replace bulky heating blocks. But heads up—it also means your machine’s cooling needs to be up to the task to keep everything around it in range.
Materials and design—built to stay steady
Inside the quartz tube, the halogen element keeps output stable over long runs and handles on/off cycling without burning out. The quartz body shrugs off thermal shock, and the coating helps manage surface temperature while keeping contaminants off the element. Then there’s the R7s connector. Two pins, straightforward wiring, and a drop-in fit for many industrial lamp holders. Simple, solid, and quick to install.
Where it shines—and what it feels like
Take a bedroom heater, for example. The shortwave infrared heats objects and surfaces directly, so you’re not wasting energy warming air. Warm-up is fast, and the unit stays compact. The 400V design lowers current draw on the line, but you’ll want a control system that can handle the thermal load. If you need intense heat in a small envelope, this is the clean, direct way to spec it—and wire it—and get on with the job.
