Getting Your Quartz IR Lamp Voltage Right
If you’re running a glass oven, you know that hitting the right thermal profile is everything. But before you even think about the heat, you’ve got to look at your power. If your quartz infrared lamps don’t match your local grid or your machine’s transformer, you’re asking for trouble—usually in the form of a burnt-out lamp or a system that just won’t get hot enough. The deal with voltage We build these lamps for 110V, 480V, and 575V. It’s not just about making sure the plug fits; it’s about how much “juice” (amperage) is flowing through your wires. See, a 110V lamp has to pull a lot more current to hit the same wattage as a 480V lamp. That means you’ll need thicker wires and beefier contactors so your terminals don’t start overheating. If you go with 480V or 575V, you drop that current. It keeps your electrical footprint smaller and stops you from losing voltage over those long cable runs. Inside the lamp These things use high-purity quartz glass to protect the tungsten filament. The magic here is that shortwave IR radiation passes right through the glass without getting stuck, hitting your workpiece directly. We can actually tweak how the filament is wound to hit the exact wattage you need. If you need a ton of heat in a tiny tube, we wind it tighter. Just a heads-up, though: cramming more wattage into a smaller space puts more stress on the ends of the quartz. Making it work in your shop We design these to be simple drop-in replacements. Whether you’re using standard R7s or specialized SK connectors, they fit snug. No wiggling, no loose connections. One thing to watch out for: when you’re running high-voltage lamps (480V+), arcing becomes a real risk if things get dirty. Keep your tubes spotless. Dust and oils are the enemy. A single smudge on the glass creates a hot spot, and that’s usually when the quartz cracks and the lamp dies on the spot. A quick clean saves you a lot of headache.
