We built this electric garage heater around a direct-radiant halogen lamp. Its whole purpose is simple: blast high-intensity heat right where you need it—on the work—without wasting energy heating the entire building. Power that just plugs in. These run on industrial voltages—230V or 400V—so you can wire them straight into your shop power. No transformer needed. We chose wattage that packs a lot of heat into a small footprint, typically 2500W to 3000W. And the tube length, around 300mm, gives you a tight, defined heat zone that slips into tight mounting spots without fuss. Built to take the heat. The halogen element sits inside a quartz envelope because quartz handles the high filament temperature and doesn’t crack under thermal shock. Inside, the halogen cycle keeps the output steady and fights blackening over time. A reflective coating on the back pushes more infrared energy forward, so you get tighter, more directional heating. And the R7s bi-pin connector makes installation solid and tool-free, with clean, repeatable contact in a compact design. Workshop-ready, day in and day out. In a garage or workshop, this setup delivers fast, localized heat—perfect for spot heating and keeping processes moving. The high wattage and short tube mean you can warm a targeted area quickly. That also means the housing and wiring are rated to handle the thermal load, so it stays safe under real-world conditions. And here’s the best part: it’s designed as a drop-in replacement for existing R7s-based heaters. So upgrading or fixing your heat doesn’t mean re-engineering the mount. You just swap it in and get back to work.
