We built this mercury lamp to be the heart of UV ink drying on high-speed printing lines. It’s a direct-fit heat source that blasts out intense UV, so inks cure the instant they need to—no smudges, no waiting around. Just keep the line moving. Power, voltage, size: the practical details A typical unit runs at 400V and 2500W, packing a lot of punch into a small footprint. We made it 300mm long on purpose—so it slides right into standard lamp housings and reflector setups. No redesign needed. And that 400V rating? It’s essential. It’s what strikes and holds the arc inside the tube. Your ballast has to match it exactly—no shortcuts. What it’s made of, and why it stays steady The tube is quartz, with a special coating that keeps UV output stable and fights off solarization, even through long shifts. The connector is R7s—double-ended, straight-wire—so the lamp locks in clean and transfers current without fuss. That means installation is quick, and contact resistance stays low. In plain terms: fewer hot spots at the ends. What it does on the line, and what to keep in mind On UV ink drying jobs, this lamp delivers the photon density needed to fully cure even dense ink layers. The payoff is consistent line speed and cure quality you can count on, run after run. Now, the trade-off: 2500W puts out serious heat. So your machine’s cooling and airflow have to be sized to handle the chamber temperature. Get the lamp matched to your setup, and it becomes the dependable, drop-in workhorse you want—quietly doing its job while the line keeps humming.
