We built these halogen drying lamps for one place: the industrial drying house. Where you need heat, and you need it fast—focused, direct, and without burning through time or energy. These aren’t your run-of-the-mill bulbs. They’re shortwave infrared emitters, engineered to dump a lot of heat right where you want it. Let’s talk power and size. The lamp is 300mm long and runs on 400V. That 400V setup is a smart move for industrial circuits—it means the lamp pulls less current for the same wattage. Less current means you can use smaller cables and you won’t lose as much voltage over distance. And the 300mm length? It slips right into tight drying chambers, so the heat stays concentrated where you need it, and you’re not wasting space. Now, what’s inside. The tube is quartz, because it can handle the shock of heating up and cooling down quickly, over and over. The outer surface has a reflective coating that pushes infrared energy forward, so more of it hits the product. The connector is an R7s, double-ended and linear. It gives you a solid mechanical and electrical fit that’s straightforward to wire and easy to swap out when you need to. What this looks like on the floor. In a drying house, you’re up against moisture and line speed. Shortwave halogen radiation cuts through surface moisture fast, so evaporation speeds up. That lets you run the line quicker without scorching what you’re drying. But here’s the reality check: you’re dealing with serious heat density. A 400V, 2500W lamp throws off a lot of power, so your machine’s cooling and airflow have to be set up right to keep ambient temps in check and protect nearby parts. If you’re an engineer who needs dependable, high-output drying with minimal downtime for maintenance, this is a straight drop-in solution that gets the job done.
