What This Heating Lamp Is

We built this quartz heating tube to be a carbon fiber heating lamp—made for industrial machines that need intense, pinpoint heat. It slips right into systems that demand a fast thermal response and a small footprint. Wire it up, and you get serious watt density without wrestling with a bulky heater.

Power, Voltage, and Size—The Real-World Details

This unit runs on 400V and cranks out 2500W, packing a lot of heat into a small space. At 300mm long, the heated zone stays tight, so you can focus that energy on one specific part or step. And because it’s shortwave, the filament comes up to temperature fast—often in seconds—so your cycle times stay short. That high voltage at this wattage is a trade-off. It lowers current compared to low-voltage options, which helps keep wiring and contactors sized sensibly. But it also means your power supply and control circuitry need to be rated for 400V. If your machine uses a different voltage, you’ll need a matching transformer or a different element.

Materials and Design: What Makes It Hold Up

The quartz envelope can take the heat and handles thermal shock well. Inside, the carbon fiber heating element keeps resistance stable as temperatures swing, so output stays consistent during long production runs. The halogen fill gas helps the filament last by cutting down on hot spots and slowing evaporation. For connections, the R7s base is a practical choice. It handles high current and gives you a secure, repeatable fit in industrial sockets. The SK15 end caps add mechanical stability and help manage heat at the seals, which eases stress on the leads.

Where It Shines—And What to Expect

Use this lamp when you need fast, focused heat in tight spots—like plastic heating zones, coating curing, and material preheating. The shortwave response gets you to setpoints quickly, and the compact 300mm size fits right into existing housings as a drop-in replacement. You’ll get strong temperature uniformity across the tube, but plan for cooling. With 2500W in a small footprint, nearby components feel the heat. Make sure the reflector, holder, and wiring around it are rated for the temperatures you’ll see.

Installation Tips (So It Just Works)

Mount the tube with proper alignment and clearance. Check the socket before you install—pitted contacts cause voltage drop and run hot. Set your controls to match the 400V rating, and make sure thermal protection is in place. Run a short burn-in to confirm stability, then set your maintenance intervals. If you’re replacing an older heater, match wattage, voltage, length, and base type. Get any of those wrong, and the heat profile shifts—and service life takes a hit.
