Forget a standard bulb. This is a proper thermal tool. It packs intense heat into a small footprint, fires up fast, and keeps the heat focused where you need it—whether you&rsquo;re heating plastics, curing finishes, or testing equipment.</p> <h2 id="power-voltage-and-size-the-practical-details">Power, Voltage, and Size: The Practical Details</h2> <p>Here&rsquo;s the thing: this lamp runs hot. Really hot. We&rsquo;re talking 2,500W to 3,000W, pulling serious current to push the filament past 2,500°C. That kind of heat demands a serious power setup, which is why we spec these for high voltage—often 400V. Why 400V? It lines up with industrial power systems, and that higher voltage means lower current. Lower current means smaller wiring, less voltage drop, and fewer hot spots at the connections. It just makes the whole circuit cleaner and safer. As for size, the 300mm length is a deliberate choice. It&rsquo;s long enough to give you a stable arc and plenty of radiating surface, but short enough to slip into tight spaces inside machinery. So you can design focused heating zones without needing a huge enclosure.</p>
