Introduction
We built these halogen lamps for one reason: dental chairs. They need serious, controllable heat in a ridiculously small space. So we made a shortwave infrared lamp that jumps to temperature the moment you need it, right where your handpiece and tools are. It’s about one thing: steady, reliable heat that fits where it has to.
Technical Deep-Dive: Power, Voltage, and Dimensions
Here’s the core of it: we typically run these at 2500W and 400V. Why? Because that combo lets us pack a lot of heat into a small quartz tube without making the lamp bulky. The tube itself is 300mm long and just 10mm across. That size gives you a wide, even heating zone, but it’s still slim enough to slip into the chair arm and leave room for your tools. And the shortwave spectrum? That’s what gives you the fast warm-up and instant response when you flip the switch. No waiting around.
Material and Design: Halogen, Coating, and R7s Connectors
The halogen cycle does the quiet work of keeping the quartz envelope clean. It sends tungsten back to the filament, which keeps the light output steady and stops the glass from blackening over time. We use high-purity quartz because it can handle the intense internal heat and stay tough mechanically. Then there’s the reflector coating. It focuses the infrared energy forward, so you get more usable heat where you need it and less stray heat where you don’t. And the R7s connector? It’s a simple, two-pin linear contact that handles the current safely and drops right in when you’re replacing a lamp. No fuss.
Application and Benefits
Inside the dental chair, this lamp is doing the heavy lifting: heating handpieces, curing components, and supporting sterilization cycles. Because it’s compact, it fits neatly into tight arm assemblies. And because it responds quickly, you get immediate control the second you need it. The halogen design stays stable for thousands of hours. But let’s be honest—2500W creates a lot of heat, so your chair’s cooling and thermal management have to be up to the task. When you wire it in with the R7s base, the install is straightforward, and you end up with a heat source that can handle the nonstop pace of a busy clinic, day after day.
