380mm 400v 2500w Shortwave Halogen Heater Lamps

Technical Deep-Dive: Power, Voltage, and Dimensions

We built this 380mm shortwave halogen heater lamp for the machines that need serious heat—fast—without taking up a ton of space. It runs at 400V, and that matters because it keeps the current lower than a 230V version would. Less current means less energy lost in the wiring, and it lets you use thinner wires inside the equipment. Then there’s the 2500W rating. That’s the “get moving” power. It heats up quickly, which can mean shorter cycle times on your process. And the 380mm length? It’s a thoughtful balance. Long enough to spread heat evenly across the target area, but short enough to slip into tight spots without forcing you to redesign the whole machine chassis.

Material & Design: Halogen, Quartz, and Connectors

Inside, you’ve got a shortwave halogen element sealed in a quartz envelope. That pairing is why the response feels so immediate—and why the output stays steady, even when you’re flipping the lamp on and off again and again. The halogen cycle helps keep the filament clean, so the wattage stays consistent over the lamp’s life. And the quartz tube is tough: it handles thermal shock and the kind of high heat that comes with running around the clock. We spec the connector as R7s—double-ended, linear contact—because it’s meant to drop right into standard fixtures. Installation is simple: line up the pins, seat the lamp, and lock it in. No drama.

Application & Benefits

This lamp is for industrial heating where you need focused infrared energy on demand—plastic processing, sealing, curing, that kind of work. Shortwave means the heat goes where you want it: right at the surface. You get a fast temperature rise without overcooking the parts around it. That speed helps keep things moving, but it also means you need to plan for it. 2500W packs a punch. Give the system proper cooling and thermal management. Set up airflow and spacing from the start, or both the lamp and nearby electronics will run hotter than intended. We built this to be a dependable, easy-to-wire replacement that puts you in control of how fast you heat up. If your process needs repeatable temperature control in a small footprint, this configuration is a practical, down-to-earth choice.
