The kind that gets the job done, and fast. So, here&rsquo;s the setup we often go with: a 400V, 2500W unit, all packed into a compact 300mm tube. It&rsquo;s intentional. Using that voltage lets us push serious power through a smaller wire, which keeps the bulb small. But it still delivers the wattage you need for a rapid temperature jump. And that 300mm length? It&rsquo;s not random. It gives you a precise heating zone that fits right into common machine openings. So you can just drop it in. No need to re-engineer the whole housing.</p>
