Gallium doped UV curing lamp

On the press floor, a good cure and a sticky mess come down to millijoules per square centimeter. No opinion—just spectral output, peak irradiance, and timing. That’s why the press builders who run serious UV lines spec our lamps as their OEM cure source: we deliver repeatable, application-matched performance, lamp after lamp, across the life of the system. The backbone of that reliability is the gallium-doped UV curing lamp. It’s still a high-pressure mercury vapor lamp at heart, but the doping shifts spectral energy toward the longer wavelengths—typically 395 nm to 405 nm—while still keeping usable output around 365 nm. That shift matters because a lot of modern UV inks and coatings are built around photoinitiators that respond more predictably in the 395–405 nm band, especially when you’re running thick films or heavily pigmented inks.
