Building the Balcony Heater: Powered by a 400V Halogen Lamp with an R7s Connection

Here’s how we built a balcony heater that actually keeps you warm. We started with a 400V, 2500W halogen lamp. The whole point? To give you that direct, focused radiant heat when you’re outside, because the smaller, low-voltage options just don’t have the muscle to get the job done.

Why We Chose 400V

Let’s talk about the voltage. We went with 400V on purpose. It lets us run a ton of power through a longer cable without that annoying voltage drop you get with standard 230V lines. And that 2500W rating? It means the heat comes on fast and stays steady, even when the wind starts to pick up. The 300mm tube focuses all that energy into a tight spot, so you’re not just heating the whole sky—you’re warming the spot where you’re standing.
