We built this room heater for industrial spaces—the kind where you need heat, and you need it now, without rewiring the whole place. It’s a quartz halogen heater, designed to pack a serious punch into a small footprint. Here’s the power, straight up. It runs on 400V and cranks out 2500W, which means the temperature climbs fast in enclosed areas. The tube is just 300mm long, so you can slip it in tight spots—right next to machinery or along a conveyor line. You get focused heat where you need it, fast. But with that kind of power, the surrounding area takes a hit. Make sure you’ve got enough cooling and ventilation to keep the overall temperature in check. What makes it hold up? The quartz tube is filled with halogen, which helps keep the filament temperature steady. That means it can handle repeated on-off cycles without burning out early. Inside, a special coating spreads the heat evenly and shields the filament from hot spots. And the R7s connector? It’s a simple, two-pin setup. Plug it in, and it works as a direct replacement for what you already have. Why you’ll actually like using it. This heater is for when you need heat that’s quick, dependable, and easy to maintain. The 2500W at 400V, the compact 300mm size, and the straightforward R7s connection make retrofits simple—so you spend less time down. The output stays steady, and the heat lands exactly where you aim it. Just double-check that your fixture and wiring can handle the current draw.
