Mercury UV lamp for textile printing

On a 24/7 textile line, downtime isn’t a metric—it’s lost rolls. And ink that doesn’t cure through? That’s rework, or worse, scrap. For predictable, high-intensity output that drives photoinitiator cross-linking through pigmented inks and thick coatings, mercury UV lamps are still the workhorse. What matters under the hood A mercury vapor lamp gives you a broad spectral output with strong peaks around 254nm, 313nm, 365nm, and 436nm. That breadth is exactly why it plays nice across multiple photoinitiator families and ink chemistries in textile work. We spec lamps by electrical power density, arc length, and end-of-life output retention. In practice, you’re chasing peak irradiance at the substrate—often 800–1200 mW/cm² in the UVA band—and enough curing energy density to clear the ink’s required dose, typically 300–800 mJ/cm² depending on opacity and coat weight. High-purity quartz envelopes keep UV transmission solid. Dichroic reflectors shape the spectral energy distribution and help keep heat off the web. Ozone-free variants exist, but you still need solid airflow and the right lamp-to-web spacing to keep substrate temperature in line. Why it holds up on textile lines Textile printing moves long meters at high speed, and mercury lamps deliver the intensity headroom to cure fast without chasing the press. The broad spectrum keeps cure consistent through pigments and thickeners, so you get better through-cure and less residual tack. That means fewer off-spec rolls, a stable print-to-cure window, and lamp replacement cycles you can plan around. The practical details you can’t skip Mercury lamps run hot, and output drops over time—expect around a 10–15% irradiance drop by end-of-life. Match the lamp arc length and reflector geometry to your printer’s web path and dwell, and make sure the power supply is compatible. Keep the quartz clean and keep an eye on substrate temperature; heat buildup will distort synthetics. And run with interlocks and shielding—UV exposure is hazardous, and proper safety design is non-negotiable.

UV curing lamp for 3D printing

We built these UV curing halogen lamps for one reason: to make your 3D prints come out right, every single time. In 3D printing, the heat has to be spot-on and steady. If it isn’t, the print quality falls apart. So we designed these lamps to pack serious, repeatable heat into a small space—the kind of tight spots you find inside most printer enclosures—and to keep running, even when your production schedule is nonstop.

These lamps run on 400V at 2500W. That power is exactly what you need to push a strong current through a long, 300mm quartz tube without losing any oomph along the way. The 300mm length is a game-changer. It gives you a wide, even cure zone that covers the whole build plate. And that high wattage? It means the lamp snaps to the temperature you need almost instantly, then holds it steady while each layer cures. Just one heads-up: with this much power, you’re going to generate heat. Make sure your printer has the airflow to keep things cool. The lamp can handle the heat, but your setup needs to keep pace.
