The Inside Story: What Makes This Desk Heater Tick

Here’s the heart of the matter: we built this office desk heater around a 400V, 2500W shortwave halogen lamp. It’s the kind of power you usually find in industrial heating setups, but packed into a much smaller space. Running it at 400V is a smart move. It keeps the current lower, which means you can get away with thinner wiring. No more worrying about voltage dropping off over distance, like you sometimes do with 230V designs. And that 300mm tube? It focuses all that heat into a tight spot, giving you serious watt-density without needing a bulky setup.
