Why that number? <a href="https://henruite.com">Because</a> in the world of high-speed curing, it’s the &ldquo;sweet spot.&rdquo; It gives you the speed you need to keep the line moving without killing your lamps every few weeks.</p> <h2 id="the-real-world-physics">The real-world physics</h2> <p>Think of the 120W/cm rating as the amount of &ldquo;punch&rdquo; hitting your material. To make sure that energy actually gets where it needs to go, we use high-purity quartz glass. If the glass is cheap, it absorbs the UV radiation; with our quartz, the short-wave UV just glides right through. Now, you might be tempted to crank the wattage higher to cure things even faster. But there&rsquo;s a catch. Push it too hard, and you&rsquo;ll fry the electrodes. At 120W/cm, everything stays stable. Your standard air-cooled reflectors can handle the heat without breaking a sweat.</p>
