We built this portable industrial heater for the plant floor—the kind of place where you need serious, focused heat, but you’re tight on space. It’s a halogen heating lamp, designed to throw a lot of heat fast, without hauling in a giant furnace. Here’s the power behind it: it runs on 400V and hits 2500W. That’s a lot of heat packed into a small footprint. The tube is just 300mm long, so the heat stays concentrated on the spot you care about—no need to warm up the whole work area. Just keep in mind: that kind of punch needs a stable electrical setup. Make sure your branch circuit can handle the load, and give the fixture room to breathe. It runs hot, and it deserves the space to manage that heat. The halogen element inside? It comes on fast and stays steady, sealed inside a quartz tube. The tube’s coating helps spread the heat evenly and shields the filament, so it can handle repeated heating and cooling without giving out early. And the connector is R7s—industry standard for this type of lamp. That means it’s a straight swap. It locks in clean, with solid contact, so you don’t end up wrestling with hot terminals or unreliable connections. This setup is made for the industrial jobs that need quick, localized heat: preheating molds, warming bearings, keeping a process warm inside a tight work cell. It’s portable because it’s compact and plugs in clean—not because it skimps on power. The trade-off is honest: you get intense heat in a small footprint. So your machine or enclosure needs enough cooling and clearance to keep everything in check—ambient temperature, parts, and the lamp itself.
