The whole point? To pack a ton of power into a small space, heating things up fast—<a href="https://o-yate.net">without</a> forcing you to overhaul your entire system.</p> <h3 id="power-voltage-and-the-right-kind-of-punch">Power, Voltage, and the Right Kind of Punch</h3> <p>Here&rsquo;s the thing about that 1000W rating on a 235V supply. It&rsquo;s a sweet spot. We wanted serious heat, but we also needed to keep the current draw reasonable for the control gear. High power density means you can heat a preform in a flash. That cuts down cycle time. And it&rsquo;s built for the real world, where the lamp gets switched on and off over and over again. But with that kind of concentrated heat, you&rsquo;ve got to plan for it. Make sure you have enough airflow and heat shielding around the lamp. Otherwise, you risk cooking the components nearby.</p>
