Let’s talk power. And size.
Here’s the thing about this under-desk heater: we packed a lot of punch into a small package. It’s a 400V, 2500W halogen lamp, all wrapped up in a 300mm body. Why does that matter? Because when you need serious heat in a tight spot, you can’t mess around. The 400V setup is smart—it keeps the current down, which means you don’t need heavy-duty wiring and you avoid voltage drop, even over longer runs. And that 2500W output? It gets that heat zone up to temp fast. No waiting around. Just quick, powerful warmth without stressing the electronics nearby.
What’s inside? Halogen, quartz, and a simple fit.
This heater is built with a quartz envelope and a halogen fill. That combo is the secret to its long life. The halogen chemistry keeps the filament stable, so the output stays consistent over time, even with frequent on-off cycling. No premature burnouts. The quartz body is no slouch, either. It handles the high temps and gives you the thermal shock resistance you need for real, industrial-level work. And the R7s connector? It’s a straight-up, bi-pin fit. So you can drop this right into standard fixtures. No adapters. No custom brackets. Just plug it in and go.
Where it shines.
This setup was made for one thing: compact, focused heat. Think under your desk, under a machine, or inside a small enclosure—anywhere space is tight but the demand for heat is high. You get that fast response and predictable output. But, and this is important, you’ve got to manage the heat. A 2500W lamp puts out a lot of local warmth, so you need to plan for clearance and airflow. Get the mounting and cooling sorted from the start. Otherwise, it’ll run hotter than you’d expect.
