Introduction

We built this USB-powered halogen heater for engineers who need serious heat in a seriously small space. Think of it as your go-to pocket powerhouse—ready the second you flip it on, delivering a tight, focused blast of infrared energy. When you’re running small-scale thermal jobs and every second counts, it’s the kind of tool that just gets out of the way and does its job.

The Inside Story

Let’s get down to the brass tacks. It runs on 400V and packs a 2500W halogen lamp inside a 300mm quartz tube. That kind of power means you get heat—fast. And once it’s up, it holds steady. But here’s the thing: all that power comes with a catch. It throws off a lot of heat. So you need to plan for that. Make sure the enclosure around it has proper airflow and cooling. This isn’t something you just plug in and forget about. That 300mm tube length is a sweet spot, though. It gives you a predictable heating zone, so you can match the heat to your part without having to build some over-the-top fixture. It just works.
