Introduction

We built the Excelitas UV lamp for one place: the industrial curing line. The kind of line where you can’t slow down, and you can’t afford surprises. The whole point is straightforward—give you steady, dependable ultraviolet output that makes UV-curable inks, adhesives, and coatings cross-link instantly. When your line is screaming along, the lamp has to fire right away, stay hot without wavering, and keep delivering the same punch, shift after shift.

Power, Voltage, and Geometry: What’s Really Happening Under the Hood

UV curing comes down to power density. You need a burst of UV intensity strong enough to kick off photopolymerization in a blink. So we built a system that leans on high voltage and high wattage, packed into a footprint that doesn’t take over your machine. A 400V input keeps ignition steady and the arc under control, even when your line voltage wobbles a bit. Pair that with 2500W, and the arc gets up to temperature fast. That matters when you need full output after a short warm-up, not after you’ve been waiting around. We size the tube length to match typical curing zones, so the UV stays concentrated across the target width. You get an even cure without having to overthink the reflector cavity. Here’s the trade-off: packing high wattage into a compact tube creates a lot of heat. Your machine needs solid airflow and reflector cooling. If the chamber overheats, output dips—and your cure consistency goes with it.
