UV exposure lamp gallium

On the press floor, metal and glass jobs are where UV curing earns its keep—and where a mistake hits hard. With these substrates, under-cured ink isn’t just a cosmetic issue. It delaminates when you handle it, when solvents hit it, when heat hits it. The real question isn’t whether UV works. It’s whether your lamp is putting out the right spectrum and enough irradiance to drive full cross-linking.

What matters, technically

Gallium-doped UV exposure lamps push more energy into the 365–405 nm window, which lines up with the photoinitiators in most metal and glass ink formulations. That targeted output boosts photon absorption at the top of the film, so polymerization kicks off fast and then builds inward. Match that with a high-reflectance dichroic reflector, and peak irradiance stays high across the arc length. You get the energy density—measured in mJ/cm²—needed for deep conversion without trying to chase it by slowing the conveyor.

Introduction

We make replacement gallium lamps specifically for exposure jobs. Think of them as the perfect plug-and-play swap for whatever system you’ve got running. They’re built to give you that steady, powerful blast of UV light, so your line keeps humming without a hitch. The whole point? Pure reliability. And they meet the standards you need, so you can upgrade without tearing your whole setup apart.

Technical Deep-Dive

We build these lamps to exact specs. The 400V setup with high wattage gives you the kind of energy punch needed for fast curing or exposure cycles. That power is matched perfectly to the lamp length, so the arc stays right where it should be. The payoff? You get a focused heat profile that gets the job done efficiently, without wasting energy heating up the housing around it.
