Introduction
We built this 235V, 1600W halogen lamp for one place: PET blow molding. It’s small, but it hits hard—delivering fast, focused heat right where you need it, for preform reheating and keeping the parison under control.
Technical Deep-Dive
It runs on 235V at 1600W, so it pulls real power. And that’s exactly the point: it gets to temperature fast, giving you the quick heat rise PET work demands—because on these machines, time is everything. The voltage is chosen to match the panels you already run, so you can wire it in without having to step down the supply. You get a lot of heat from a tight footprint. Just keep in mind: the surrounding fixtures need to be ready for the extra warmth.
Material & Design
Inside, you’ve got a halogen-filled quartz envelope. It keeps the filament stable even at high heat and helps fight blackening over time, so output stays steady shift after shift. Then there’s the R7s base—simple, tough, and made for high current. It’s a drop-in replacement in most standard holders, so you get solid contact and repeatable alignment. That means fewer headaches and less downtime when it’s time to swap lamps.
Application & Benefits
On the PET blow molding line, the lamp focuses on the preform walls, heating them quickly and evenly before stretching. That concentrated heat helps you stay inside the process window without overheating the material—so you can protect clarity and strength. It responds fast, which helps you keep control on high-speed machines. Here’s the trade-off: with that much wattage, you do need proper airflow and thermal shielding. That’s how you protect nearby components and keep everything running at a safe temperature.
