The Specs, But Make It Real
Let’s talk about this greenhouse heater the way you’d actually talk about it—like something that solves a real problem. It’s a 400V, 2500W shortwave halogen infrared lamp, and it’s 300mm long. Why 400V? Because when you’ve got long runs in a greenhouse, that higher voltage keeps the current lower, so you don’t need thick, clunky wiring. And the 2500W? That’s how you get serious heat in a small footprint. You can warm just the zone you care about, without turning the whole structure into a sauna. The 300mm length keeps the emitting area tight, so you can mount it close to plants without eating up headroom. When the thermostat calls for heat, it responds fast. No waiting around.
The Build: Simple, Tough, Thoughtful
The tube is quartz, filled with halogen, and coated. That coating is there to keep output steady and protect the filament, so you don’t get that annoying fade over time that throws your climate off. It connects via an R7s two-pin interface—no adapters, no hassle. You wire it in and you’re done. The bi-pin contact is built to handle the 400V load without getting sloppy.
What It Feels Like to Use in a Greenhouse
Here’s the magic: it delivers heat right where you need it—on the crop line—without pushing air around. That means less spreading humidity and fewer headaches with disease pressure. The power density gives you quick recovery after nighttime setbacks, and the size fits tight spaces like benches and narrow aisles. Now, a heads-up: 2500W at 400V is serious, so you’ll want proper fusing and a fixture that can handle the heat. Plan your load and cooling, and you get predictable, controllable warmth with minimal fuss.
