They go down because the UV output slips below the energy the ink system needs to fully cross-link. As mercury <a href="https://henruite.com">lamps</a> age, the spectral output <a href="https://goldisgood.com">drifts</a>, reflectors lose reflectivity, and peak irradiance collapses. The result is predictable: incomplete cure—tacky surfaces, adhesion issues, and the need to throttle back press speed just to avoid defects.</p> <h2 id="what-matters-technically">What matters, technically</h2> <p>We build high-intensity UV lamps that hold steady output, tuned for mercury vapor emission. You get strong energy in the 365 nm band, plus usable output in the 385–405 nm range so you can match the photoinitiator package. Peak irradiance is engineered to exceed 12 W/cm² at the arc, and in typical press setups, the curing energy density on the substrate runs above 800 mJ/cm². The reflector uses a dichroic coating to bounce the useful UV while letting heat pass through. That improves spectral efficiency and keeps substrate heat load in check. Depending on power density and how you run the lamp, life targets are 2,000–5,000 hours, with output held steady through controlled arc stability and <a href="https://o-yate.net">consistent</a> quartz transmission.</p>
