We built these dimmable patio heaters for people who crave control—engineers who want outdoor comfort that just works, every single time. Here’s the magic: they use shortwave infrared halogen elements to put the heat exactly where you need it. No wasted warmth drifting off into the night air. Just direct, localized comfort. Power, voltage, and the nitty-gritty We tune the heating element to a specific wattage and voltage—usually 2500W, either at 230V or 400V, depending on what the site’s electrical setup can handle. The tube stays compact, around 300mm, so the heat concentrates into a small footprint. That tight geometry delivers serious heat density. But it also means the fixture and wiring have to be built for the long haul, handling the constant current without breaking a sweat. We run the lamp hot, so the reflector and housing are engineered to take the heat without warping or drifting. What’s inside: the details that matter Halogen keeps the filament steady, even at scorching temperatures. That means the heater fires up fast and keeps delivering steady output over the life of the lamp. The quartz envelope handles the thermal shock, and a selective coating shapes the infrared spectrum so the warmth stays focused. We chose an R7s base for a reason: it’s a solid, two-terminal connection that’s easy to wire, holds alignment, and stays stable even when things get a little shaky. For certain assemblies, we also use SK15 fittings to match specific mounting rails and make service access straightforward. Why it feels so good in real life Out on the patio, the dimmable control is a game-changer. You dial the heat to match the crowd, the weather, the mood. The shortwave infrared profile warms people and surfaces directly, so you’re not paying to heat empty air. And because the tube is compact, the unit slips into slim housings that stay out of the way while still throwing serious radiant warmth. One trade-off: packing that much power into a small envelope means the fixture needs proper airflow and smart heat management. We built for that reality, so you just feel the comfort.
