Portable Halogen Heater: 400V, 300mm, R7s Heat for Home and Workshop
We built this portable heater for folks—engineers, makers, anyone—who needs serious heat in a tight spot. You want something compact that fires up fast and just stays steady, whether you’re at home or in a light workshop. The heart of it is a 300mm halogen tube, putting out 2500W at 400V. That gives you focused infrared heat without taking up much space at all.
Power, Voltage, and Size—Straight to the Point
This thing runs at 400V, so it pulls a strong current. That’s exactly why it warms up almost instantly and packs a lot of heat into a short 300mm length. Perfect when you need intense, concentrated warmth in a small area. Just keep in mind: the circuit has to be ready for it. Make sure your fusing, wire gauge, and connections are all properly matched to the load.
Built to Run Hot—and Keep Doing It
The halogen element lives inside a sealed quartz envelope. That means it can run hot and bright without the output fading quickly. And the R7s connection? It’s a straightforward, double-ended design. Changing the tube is a simple drop-in job—no adapter plates, no messing around with complicated wiring. The outer coating helps spread the heat evenly and protects the element from those concentrated hot spots that can cause trouble.
Where It Shines—And What to Watch For
Use this heater whenever you need quick, directional heat—spot warming, process support, or keeping a specific area comfortable. The short length, high wattage, and standard R7s termination make installation easy, and the output stays predictable. Just be mindful: it runs hot, so give it enough clearance and ventilation. And the quartz envelope can crack if it gets bumped or handled roughly during setup and mounting.
