It’s direct-radiant, designed for industrial work where you want the heat to show up fast, behave predictably, and take up as little room as possible.</p> <h2 id="power-voltage-and-size-the-practical-trade-offs">Power, Voltage, and Size: The Practical Trade-Offs</h2> <p>It’s rated at 800W because we wanted high heat density without forcing you to run huge wiring. Run it at 400V and the current stays lower than many low-voltage lamps, <a href="https://henruite.com">which</a> helps reduce voltage drop over longer runs and keeps terminal temps from climbing. The 400mm length? That gives you a clean, focused heating zone without wasting real estate on the machine. Here’s the trade-off: you get intense, localized heat. That’s the point. But it also means your reflector and mounting setup need to be built to handle that concentrated thermal load—so nearby parts don’t get cooked.</p>
