Out on the press floor, a great print is more than just ink—it’s photon energy delivered exactly where it needs to be. When the lamp doesn’t pull its weight, you get incomplete cross-linking, adhesion that fails, and a pile of rework. We’re here to make sure the light behind every sharp, durable image is up to the job, with voltage choices that match the plant’s wiring, not wishful thinking. What matters, electrically speaking We size UV lamps around three real-world voltages: 110V, 220V, and 380V. Pick the right one and you cut current draw, keep conductor sizes sane, and reduce I²R losses in the supply and ballast runs. The lamp itself is a high-pressure mercury vapor source, built to hold steady spectral output across the UVA band. Peak irradiance stays consistent at the arc, and the reflector’s dichroic coating shapes the spectrum to fit the photoinitiator absorption profile. Curing performance comes down to delivered energy density (mJ/cm²), not just wattage on a label. Keep the wavelength envelope stable—centered where your ink cures fastest—and the cure window stays repeatable, job after job. Why this plays in industrial printing In offset, flexo, and screen, throughput hinges on curing fast without scorching the substrate. These lamps deliver output you can count on, so you can push speed without chasing marginal cure. The voltage flexibility lets you standardize lamps across lines—110V for compact setups, 380V for the big presses. The payoff is shorter makereadies, fewer off-spec sheets, and less energy per cured meter. The practical details Match the lamp to the ballast and reflector geometry. Mismatched arc lengths and ignition profiles will skew the spectral curve and shorten service life. Check the substrate’s tolerance to peak irradiance, and make sure ozone management is handled at the exhaust. And expect output to decay over time—replace on accumulated hours, not the calendar.
