We build commercial patio heaters for restaurants, and honestly? The heart of the whole system is a halogen heating lamp that’s built to work—not to look pretty. This isn’t some residential bulb. It’s a serious heat source, designed for outdoor comfort when the temperature takes a nosedive. Here’s the thing: these lamps are spec’d for industrial duty. Most run at 230V or 400V, pulling 1500W to 2500W, so you getinstant radiant heatthat covers a big seating area. The tube is usually around 300mm long, which gives you enough radiating surface to warm a crowd while keeping the heater itself from taking up too much space. High wattage in a short length means serious heat density, so the fixture has to handle that load. That’s why it leans on sturdy reflectors and smart airflow—keeping things running safely, even when it’s working hard. Inside, the lamp runs on a halogen cycle inside a quartz envelope. Quartz handles the shock of flipping on and off quickly, and it runs hotter than glass. That heat keeps the element clean and keeps output steady. The halogen chemistry also stops blackening, so the infrared heat stays consistent over the lamp’s life. And we use an R7s connector because it’s straightforward—two pins, line voltage, and a direct fit for many commercial heater sockets. That means replacements are fast, and wiring stays simple on the shop floor. In a restaurant, you need heat that turns on the second you need it and stays steady, even when wind and drafts are doing their thing. These lamps warm people and surfaces directly—no waiting around for air to heat up. The R7s connection and standard tube size also make installation and maintenance easier, so you spend less time down during service. But yes, there’s a trade-off: the lamp runs hot. So you’ve got to respect the heater chassis and clearances. Keep that in mind, and you’re good.
