Let’s talk about the 370mm 2000W Shortwave IR Lamp

If you’re looking for a heat source that doesn’t mess around, this is it. We built this lamp for those moments when you need a massive hit of heat right now. Since it uses shortwave infrared, it doesn’t waste time warming up the air in the room. Instead, the energy punches straight through to your material. It’s fast. Really fast. The power behind the glow Packing 2000W into a 370mm tube creates some serious heat density. Inside, there’s a tungsten filament swimming in a halogen gas mix. That gas is the secret sauce—it stops the filament from evaporating too quickly, so the lamp doesn’t just burn out the moment you put it to work. We used a transparent quartz envelope for a reason. It lets that shortwave radiation fly right through without getting trapped, meaning all that energy lands exactly where you want it: on your workpiece. Getting it set up Installation is the easy part. It uses an R7s base, which is basically a push-in connector. You just slide it into the socket, lock it in, and you’re good to go. No need to spend your afternoon wrestling with complex wiring. But here is a pro tip:do not touch the glass with your bare hands. I know it sounds picky, but the oils from your skin leave invisible marks. Once the lamp hits full power, those spots become “hotspots” that can actually crack the quartz. Use a clean cloth or gloves. Your future self will thank you. A few things to keep in mind Because this thing ramps up so quickly, it can sometimes overshoot your target temperature. If your PID controller isn’t dialed in just right, you might find things getting hotter than you intended. Also, keep an eye on your reflectors. With this much energy concentrated in one spot, a crooked reflector doesn’t just waste power—it can actually warp your machine’s housing. One last thing: check your power supply. These lamps have a bit of a “kick” when they first start up, so make sure your breakers can handle that initial surge so you aren’t constantly resetting your power in the middle of a job.
