Gallium Iodide Lamps: The Secret Weapon for Deep-Cure Exposure in Textile Printing
We built our Gallium Iodide lamps for one reason: to give textile printers a cure they can actually trust. Not just a surface that looks dry, but a cure that goes all the way through. If your prints are cracking after a wash, you’re missing the kind of penetrating power that gets the ink to fully set. Our lamps deliver that deep-cure intensity, so your colors stay bold and your work holds up.
Let’s talk power: the kind that actually gets the job done
These lamps are all about high-intensity output. They run on 400V, which is what creates that short-wave, high-energy UV profile. It’s the muscle you need to push through thick layers of ink and hit the bottom of the stack, not just the top. We match the wattage and length to the exposure footprint. Our standard setup hits 2500W across a 300mm active arc length. That gives you even exposure across the whole width—no hot spots, no cold spots. It’s serious power, and it does mean your power supply and cooling have to be up to the task. Make sure your ballast and cooling system are ready for the heat.
The magic is in the chemistry
Here’s the thing that makes these lamps different: the gallium iodide fill inside the quartz tube. It shapes the spectrum to hit the photopolymer initiators right where they live—in screen-making and curing. That means the wavelengths target the reaction deep inside the ink, not just on the surface. The quartz envelope handles the high temperatures and keeps the UV transmission strong. And the R7s connector? It’s a solid industrial fit. It gives you a secure connection and makes swapping out lamps a simple drop-in job. These lamps are built to handle the thermal swings of a busy shop, but like any high-output tube, they need careful handling and a stable mount.
What this looks like on your floor
In textile exposure, consistency is everything. You need the lamp to deliver steady intensity to set the screen and cure the ink, shift after shift. Our Gallium Iodide lamps bring the deep-cure performance that cuts down on wash cracking. The payoff? Better color fastness, and prints that survive repeated washing without falling apart. Installation is straightforward. The R7s base drops right in, and the 400V/2500W profile lines up with standard exposure units. The lamp stays stable through long runs, but remember: more power means more heat. Pair it with cooling that’s properly rated, so the exposure chamber stays at the right temperature and your substrate stays protected. If you’re tired of post-wash failures, you need a lamp built for depth, not just brightness. We spec these to do the work, day in and day out, so your prints come out right—and stay right.
