The secret? A 400V, 2500W halogen infrared tube, packed into a compact design that puts out serious warmth.</p> <h2 id="why-400v-2500w-and-that-specific-size">Why 400V, 2500W, and that specific size?</h2> <p>The 400V rating isn’t just a number. It keeps the current lower, which means less copper in the wiring and less voltage drop over the line. And that 300mm length? It concentrates all that power into a tight zone, so you feel the heat fast—predictable, right where you need it.</p>
