Panel Heater: 400V Halogen Shortwave Lamp with R7s Connector
We built this panel heater to be a straight-up, drop-in heat source for industrial machines that need serious power in a tiny package. It’s a halogen shortwave lamp, designed for one thing: getting hot fast and staying steady, even when it’s crammed into a tight spot.
Let’s get into the details.
This thing is rated at 2500W and 400V, which means it packs a ton of heat into a small footprint. The lamp itself is 300mm long and just 10mm wide, so it slips right into crowded reflector setups without pushing other parts around. And that 400V rating? It keeps the current down, so you can keep your wiring short and avoid voltage dips.
What it’s made of, and why it matters.
The shortwave halogen element fires up almost instantly, giving you that intense infrared heat. No waiting around. The quartz tube is coated to keep the output spectrum consistent and shield the filament from gunk, which helps the lamp stay stable over time. And the R7s connector? It’s a solid, two-point connection that’s easy to wire up and stays put, even when the machine is shaking and the heat is cycling.
Where it shines.
This lamp is your go-to when you need focused heat with almost no warm-up delay. Think panel heaters, plastic processing zones, or drying stations built right into the machine. But here’s the thing: it throws off serious heat. So plan your clearance and cooling. If the surrounding area can’t shed that heat, the lamp will run hotter, and that shortens its life.
