Introduction
Picture this: you’re in your workshop or lab, and you need warmth right where you’re working—not a blast of heat that turns the whole room into a sauna. That’s exactly what we built this desk-mounted heater for. It’s small, focused, and gets straight to the point. A 300mm halogen quartz lamp throws out direct radiant heat, so you feel the warmth on your hands and face without wasting energy heating the entire space.
The Power Behind the Warmth
This thing runs on a 400V supply and pulls 2500W. That’s a lot of heat packed into a tiny footprint. The 300mm tube is intentionally sized to fit neatly on standard desk mounts—no awkward overhang. It heats up fast. Seriously fast. But that also means your circuit and fixture need to be ready for a steady, heavy load.
What It’s Made Of
The lamp uses a quartz envelope with a halogen fill. Why does that matter? It keeps the filament stable even when things get scorching, and it helps prevent that annoying blackening over time. So the heat stays consistent, day after day. The R7s connector is ceramic-based and handles the high current and high temps at the ends of the tube. It’s a straightforward, drop-in replacement for what you’ve already got.
Who It’s For, and Why It Works
This heater was made for engineers who need heat right now—right at their workstation. Think control panels, test benches, inspection points. Radiant heat means no dust being blown around, which is a huge win in a clean workspace. And the slim tube design keeps it out of your way. Here’s the trade-off: you get intense, focused heat, but you do need to keep an eye on airflow and clearance to make sure nearby components stay cool.
