We built our lab glass annealing lamps for one reason—to put you in the driver’s seat of your heat profile. This isn’t just a heat source. It’s a precision tool, made to ease out the stress inside glassware without creating thermal shock. And we don’t stop at selling you a lamp. We send our engineers right to your shop floor to map out your whole thermal system, so the lamp we spec fits your process like a glove. Power, voltage, and size—what it all means for you At the heart of this system is a high-intensity halogen lamp, built to deliver heat that’s fast and focused. The power density matters—there’s no cutting corners when you’re annealing. A 2500W output at 400V gives you the heat flux needed to bring glass up to temperature quickly, so you hit the annealing point without wasting time. The 300mm tube length? That was chosen on purpose. It matches the standard footprint of most lab annealing ovens, covering glassware evenly—no hot spots, no cold spots. And because it’s compact, you can retrofit it into your existing equipment with minimal fuss. Material and design—built to take the heat We wrap the tube in quartz. It handles the high heat and repeated thermal cycling that would crack ordinary glass. Inside, the halogen cycle keeps the filament clean, which means steady light output and consistent heating over the life of the lamp. The R7s connector is the workhorse interface. It’s a secure, high-current connection that’s standard across industrial heating gear. Easy to wire, and built to handle thermal expansion and electrical load without giving up. It’s a drop-in part, made for reliability in a harsh, high-heat environment. Application and benefits—engineers working with engineers Here’s where the real value shows up. We don’t just hand you a 2500W lamp and say goodbye. Our engineers come to your facility, look at your glass, your oven, your cycle times, and then spec the exact lamp configuration to match your thermal load. That on-site diagnosis makes sure the lamp runs at its rated performance without straining your electrical setup. Yes, this level of power density means you need a cooling and power system sized for the job. But when it’s spec’d right, you get an annealing process you can count on, day after day—one that keeps rejects out of the bin. We don’t just provide the lamp. We deliver the solution.
