Wall-Mounted Outdoor Halogen Heater: 400V Power, R7s Connection, and a 300mm Footprint
We built this wall-mounted outdoor heater for the plant floor—the kind of place where you need serious heat in a seriously small space. It’s a 400V halogen infrared tube, just 300mm long, cranking out up to 2500W. Designed to wire up fast and tough it out in the elements.
Power, voltage, and size—why it matters
Here’s the thing about the 400V supply: it lets you push higher wattage over longer cable runs without the voltage dipping at the terminal. That means you get consistent power, even when the run isn’t short. And the 300mm length? It focuses the heat into a tight zone. So you get a lot of heat density without giving up mounting space. It warms up fast, and the moment that lamp strikes, the output is immediate.
The guts: halogen, coating, and the R7s connection
The halogen element runs hot—and steady. The quartz envelope handles thermal shock without cracking, so it doesn’t get brittle when the temperature swings. A special coating keeps output consistent over time, even as the element cycles on and off. And the R7s connector? It drops straight into standard sockets. No adapters. No messing around. It clicks in solid and stays put, even when things are vibrating.
Where it shines: outdoor heat, easy install
Mount it on a wall, aim it where you need it, and it throws direct infrared heat right at targets, equipment, or work areas. The footprint is small, so the unit stays out of the way. The R7s termination speeds up the install because you’re not hunting for extra parts. One note, though: that high heat density needs proper airflow and heat management. Make sure surrounding components aren’t getting cooked. Give it room to breathe, and it’ll do its job—no fuss.
