Technical Specifications and Application of 1600W R7S Quartz Halogen Heating Lamps

Let’s Talk About the 1600W R7S Quartz Halogen Lamp

If you’re running high-intensity drying or curing, you know that timing is everything. That’s why we built these 20.25-inch halogen lamps. At 240VAC and 1600W, they don’t just warm up—they hit you with a concentrated blast of heat exactly where you need it. We use a high-purity quartz envelope because it can take a beating. It handles the thermal shock without cracking and stays crystal clear, letting that shortwave infrared energy fly right through.

Speed and Power

Here is the best part: there is no waiting around. These lamps hit their operating temperature almost instantly. If you’re running a conveyor line where a part is only under the heat for a few seconds, that speed is a lifesaver. Plus, we used the R7S base. It’s a simple, secure fit, which means when a tube finally burns out, you can just swap it for a new one and get back to work without messing with the wiring.

Why Quartz Matters

You can’t just use any glass here. It would warp or melt. Quartz is the only thing that actually holds up at these temperatures. Inside the tube, the halogen cycle does the heavy lifting. It stops the tungsten filament from evaporating and clouding up the glass. Cheap glass turns milky over time, and once that happens, your heat output tanks. With these, the tube stays clear, and the lamp lasts longer.

Getting the Most Out of Them

These are basically drop-in replacements for most industrial ovens or PET heating setups. They pack a massive amount of heat into a small space, but that comes with a catch. You’ve got to keep your reflectors clean. If they’re pitted or covered in grime, you’re wasting a huge chunk of that IR energy—and your housing might start to overheat. Also, double-check your wiring. 1600W is a heavy load. Make sure your gauge is thick enough to handle it, or you’ll deal with annoying voltage drops at the terminals.
