A spectrum that&rsquo;s off doesn&rsquo;t just slow you down—it throws off the photoinitiator chemistry. You end up with uncured monomers and cross-linking that&rsquo;s all over the map. You need a UV curing lamp that acts like a precision tool, not a heat gun with a <a href="https://henruite.com">broad</a> output.</p> <h3 id="what-matters-technically">What matters, technically</h3> <p>We build the lamp around controlled spectral output, usually nailing a narrow band at 365nm or 395nm, depending on the photoinitiator package. Peak irradiance is tuned so you hit the required light energy density at the coating surface—often 500–2000 mJ/cm² for full cross-linking—without cooking the stone. A dichroic reflector and a quartz envelope keep the spectrum stable, so the photoinitiator absorbs efficiently and the cure happens in seconds. The payoff is repeatable conversion, not seat-of-the-pants guessing.</p>
