Let’s talk about what makes this heater actually work.
We built this electric heater around a 400V, 2500W halogen tube that’s 300mm long. That’s not just a random set of numbers. Here’s the why: running at 400V keeps the current lower for the same wattage. That means less voltage drop across the line, and you can get away with smaller wiring. And the 300mm length? It gives you enough surface area to blast 2500W of heat into a tight zone—without having to build a bulky, oversized assembly.
The guts: halogen, a smart coating, and an easy fit.
Inside, you’ve got a quartz envelope filled with halogen. This design keeps the filament temperature steady, which fights that annoying blackening and keeps the output consistent over the tube’s life. And that gold coating on the glass? It reflects infrared heat back toward your target. So more of the warmth goes exactly where you need it, and less of it spills over and heats up surrounding parts. Then there’s the R7s connector—a straightforward, bi-pin fit. That means this tube drops right in as a replacement for many existing fixtures. No fuss.
Heat on demand, where you need it most.
This setup was made for industrial work that needs fast, localized heat. Think heating plastic, curing adhesives, or spot drying. The heat density is high, so you get a rapid temperature rise. That also means your machine’s cooling and clearance need to be properly set up. The payoff is simple: a low-cost electric heater that installs quickly, runs hard, and puts the heat exactly where the job calls for it.
