Power in a Tiny Package
We built this infrared lamp for mobile glass repair rigs—the kind of job where space is tight and you can’t just plug into an endless power supply. The whole challenge? Cramming serious heating power into a small footprint without tripping the circuit. So we went with a high-density halogen infrared emitter. It throws heat exactly where you need it, fast, right onto the borosilicate glass. Here’s the simple part: it’s a 400V, 2500W setup packed into a 300mm tube. We chose that ratio on purpose. It gives you intense heat without demanding a huge current draw, which keeps the wiring slim and the unit compact. And that 300mm length? It’s a sweet spot. Enough heating zone for standard repairs, but short enough to slip into a mobile gantry or a handheld frame without fighting for room.
The Heart of It: Halogen and the R7s Fit
Inside, you’ve got a halogen-filled quartz envelope. Why? Because it responds instantly and stays steady. The halogen cycle takes evaporated tungsten and sends it back to the filament, which keeps the glass clean and the output consistent. After thousands of hours, you still get the same reliable heat profile, which matters when you’re curing glass and can’t afford surprises. Then there’s the R7s double-ended connector. This isn’t just “nice to have.” It anchors the lamp at two points, so it holds steady when the truck is bouncing down the road. It also keeps the electrical contact solid, cutting down resistance at the terminals—so you don’t get hot spots that kill bulbs early.
Heat That Works on the Road
This setup was born for field work. The power density is high, so the lamp hits operating temperature quickly. That means shorter cycles and faster turnarounds on a repair. We tuned the infrared spectrum to be absorbed well by borosilicate glass, so the heat goes into the material—not into heating the air around it. Now, the catch is real: 2500W in a 300mm tube makes for some intense localized heat. You’ve got to plan for it. The mounting bracket needs enough clearance and airflow, or you’ll want to add active cooling. Get that right, and you’ve got station-grade heating performance in a package you can move, set up, and trust to finish the job.
What It’s For, and How It Performs
This lamp was made for mobile glass repair supports. It delivers the heat you need to cure adhesives and reshape damaged borosilicate sections. With high wattage, a compact size, and the R7s connector, it’s basically a drop-in upgrade for field service gear. It runs hard. It heats fast. And it takes the bumps of the road without whining. Just remember: that 2500W output means you need a solid cooling plan right around the fixture. Give yourself proper clearance and ventilation, or those nearby electronics and components will bake.
