We built the 420nm Gallium UV Lamp for one reason: to be a focused heat machine. Not a do-everything bulb. It’s all about delivering serious, controllable infrared energy—exactly when you need it—where industrial work demands a fast response and rock-solid output. Here’s the guts of it: a 420nm gallium UV emitter running at 400V and 2500W, packed into a 300mm tube. That kind of power density means it wakes up fast and concentrates the heat where you want it. The 400V rating keeps the current lower on longer runs, so you get less voltage drop and your power supply stays happy. And the 300mm length? It lines up neatly with standard concentrator zones—easy to mount, easy to shield, and simple to aim at the part. Inside, the halogen cycle works inside a high-purity quartz envelope. That keeps the filament steady even at high temps, so the output stays consistent over time. The quartz handles rapid heating and cooling without cracking, and it lets the UV output through for the process chemistry you’re running. Then there’s the R7s bi-pin connector. It’s the kind of industrial-grade plug that just drops in on a lot of machines—quick to wire, secure in the socket, and built to take heat and shop-floor vibration without fuss. You choose this lamp when you need heat on demand that you can count on, again and again. It shines in curing, drying, and polymer processing, where that 420nm output helps drive the reaction you’re after. A heads-up, though: that 2500W density means you need proper cooling and careful reflector alignment to avoid hot spots. Treat the cooling and mounting as part of the setup, not an afterthought.
