Introduction
Picture this: you need serious heat, but you’re working in a tight spot. You can’t afford to redesign the whole machine just to fit a heater. That’s exactly why we built the 118mm Ruby Halogen Heat Lamp. It’s a compact powerhouse, designed to deliver intense infrared heat right where you need it. It’s rated at 400W and runs on 220V, and it’s got an R7s base, so it slips straight into the standard ceramic holders you already have.
Let’s Talk Power, Voltage, and Size
The magic here is the 118mm length. It’s short enough to pack into dense heater arrays without forcing you to overhaul your equipment. And that 400W rating at 220V? It gives you predictable heat density, so you can figure out exactly how many lamps you need to hit your target temperature. Since this is an infrared emitter, it delivers energy as radiant heat, not by wasting time heating the air. The result? It warms up fast and avoids all that unnecessary convection heat. Now, there is a trade-off. Packing 400W into a short tube means the surface gets seriously hot. So, your machine needs to offer enough clearance and ventilation. And that reflector or guard has to be up to the task, keeping nearby parts from overheating.
What’s Inside Matters
That ruby-tinted quartz envelope isn’t just for looks. It filters out the visible light and focuses on shortwave infrared—the kind that plastics and coatings absorb like a sponge. Inside, the halogen cycle keeps the filament clean, even at scorching temperatures. This means stable output over the life of the lamp, with way less of that blackening you see on ordinary bulbs. The R7s connector is a no-brainer for industrial use. It gives you a solid, two-point contact that can handle repeated heating and cooling cycles, and it makes replacing the lamp on the line a simple job. We run it on 220V because that’s what most plants use, but you still want to double-check that your wiring and control circuit are rated for the full load.
Where It Shines
This is your go-to lamp when you need focused heat, fast, in a small space. Think plastic sealing, adhesive curing, drying components, or localized preheating. Its compact size lets you build modular heater blocks that are a breeze to service. The halogen design keeps the output steady, and thanks to that R7s base, swapping out a lamp is a quick fix, not a full-on rewire. For best results, pair the lamp with a reflector that puts that infrared energy right on the target. And make sure your thermal control can keep up with the required duty cycle.
