Getting Your Infrared Tube Voltage Right
Clear quartz infrared lamps do the heavy lifting when it comes to curing and drying. But here is the thing: when these tubes fail, it’s rarely because the quartz gave out. Most of the time, it’s because the lamp’s electrical specs and the building’s power grid are fighting each other.
The trick to voltage
Most lamps you find on a shelf are set to 230V. That works for some, but if you’re setting up a shop in North America or dealing with a heavy industrial site, you’re probably looking at 110V, 480V, or 575V. We don’t just slap a transformer on there to make it work. Instead, we actually change the length and diameter of the tungsten filament. We tweak the hardware itself so it hits the right wattage for your specific voltage. Plus, there’s a practical perk to going higher. A 480V tube pulls less current to get the same amount of heat as a 110V tube. That means you can use thinner wires and put way less stress on your switchgear. It just makes the whole setup cleaner.
A word on the quartz
We use high-purity clear quartz because it lets short-wave IR pass straight through. The heat goes right to your target instead of getting trapped in the tube wall. But you have to be careful when you’re installing them. Clear quartz hates skin oils. If you touch the glass with your bare hands, those fingerprints create little hotspots. Once the lamp heats up, those spots cause the glass to crack.**Always wear lint-free gloves.**Trust me on this one.
Making it fit
We design these to be simple drop-in replacements. Whether you need a specific length or a weird end-cap, the electricals have to be a perfect match for your grid. If you plug a 230V lamp into a 480V line, it’ll pop in seconds. On the flip side, if you under-volt it, you’ll get weak heat and your cycle times will drag on forever. To get the intensity and wavelength you’re actually paying for, the power supply and the lamp need to be on the exact same page.
