We built this mini space heater to be a compact powerhouse—a shortwave halogen lamp that throws serious heat, fast, in those tight industrial spots where you just can’t spare a lot of room. Here’s the thing: it packs a ton of heat into a tiny footprint. Running at 400V keeps the current draw lower for the wattage, so your wiring and line-side contacts stay happier. And with 2500W on tap, the temperature climbs quickly. The whole unit is just 300mm long, so all that energy gets focused into a narrow target zone. When space is tight, you get a lot of heat right where you need it. The heart of it is the shortwave halogen element—built to run hot and respond fast. The quartz envelope takes the thermal shock without cracking, and a specialized coating helps keep output steady by limiting degradation at those blistering filament temps. And the R7s end-cap? It’s a proven industrial standard, so installation is a straight-up drop-in on compatible fixtures. Wiring stays clean, and it holds steady even when things get shaky. This is the configuration you reach for when you need quick, localized heating—pre-heating zones, drying components, or curing a small area. The response is fast, the heat is concentrated, and the profile is slim enough to slip into crowded machines. Just keep one thing in mind: with 2500W packed into a short tube, the surrounding gear is going to feel the heat. Make sure your cooling and clearance specs are squared away before you run it.
