Under desk heater

We built this under-desk heater around a high-density halogen tube, because when space is tight, you need heat that’s focused and compact. It slips into snug spots and throws off direct radiant warmth—no bulky convection parts getting in the way. Here’s how it punches. It runs on 400V and pulls 2500W through a 300mm tube. That’s a lot of heat packed into a short body, giving you high heat flux without needing a long heater. You feel the temperature rise fast. Because the power is concentrated, your control circuitry and local ventilation need to be properly rated. We’ve made sure the lamp can handle the electrical load, but you’ve got to match it with the right supply and cooling on your end. What’s inside, and why it matters. Halogen keeps the filament running hot and steady, and the quartz envelope handles the shock of frequent on/off cycles without blinking. A reflective coating pushes more output forward, so more warmth lands where you aim it and less gets wasted sideways. And the R7s connector? It’s a simple, proven way to wire it—just line it up and clamp. No special tools, no fuss. Where it shines. In under-desk setups and compact equipment layouts, this is the kind of heat source you can drop in and get moving quickly, with output that stays predictable. You get tight thermal control in a small footprint, and the halogen design keeps its cool through repeated cycles. The trade-off is straightforward: high heat density means you need solid cooling and the right voltage match. But when you need concentrated warmth in a confined space, this approach just works. Reliably.
