700mm 415v 2500w infrared tungsten heat lamp replacement infrared halogen lamp

May 9, 2026

Introduction

We built this 700mm infrared tungsten heat lamp to be a straight swap for the infrared halogen units already in your setup. It’s made for industrial heating—where you need intense, focused radiant heat, fast, and in a standard tube size. Rated at 2500W on a 415V circuit, it packs serious heat density without overloading typical three-phase power. In other words: you get a lot of power where you need it, without the electrical headache.

Power, Voltage, and Size—What It Really Means on the Floor

At 700mm long, the lamp gives you a solid emitting area. That length helps spread the heat across the target more evenly, which matters when you’re running consistent cycles. And with 2500W, this thing comes up to temperature quickly and holds steady under load. No long warm-up wait. No drift when the line is busy. The 415V rating is designed for three-phase industrial supply, which keeps the current lower than you’d get on a 230V alternative. Lower current is good news: you can run smaller wiring, and you get less voltage drop over longer cable runs. But here’s the part you can’t ignore—this wattage throws off a lot of heat. Make sure the fixture and the machine enclosure have enough airflow and thermal headroom. Plan for it, and you won’t be chasing overheating issues later.

Inside the Lamp: Filament, Quartz, and Connections That Stay Honest

Inside, a tungsten filament runs in a halogen gas fill. That chemistry helps reduce blackening on the inner quartz envelope by sending evaporated tungsten back toward the filament. The payoff is stable output over time and a longer service life than you’d get from a standard incandescent element. The quartz tube is tough enough to handle rapid on/off cycling without cracking under thermal shock, and it stays highly transparent in the infrared range—so the heat goes where you want it. Out at the ends, the terminations are built for industrial mounting and solid contact. Wire it up, and it stays connected. No worrying about hot spots forming at the joints.

Where It Shines: Curing, Drying, Preheating, and Testing

This lamp is for the places on the floor where infrared heating is the right tool—curing, drying, preheating, or component testing. And the best part? It’s a drop-in replacement. You can install it into your existing fixtures without redesigning the machine footprint. That saves time, and it saves head-scratching when you’re trying to keep a line running. The fast thermal response means less idle time during startup. And because the output is focused radiant heat, you’re heating the product directly—not wasting energy heating the air around it. Just remember: this much power density deserves respect. Keep the area around the lamp and fixture properly cooled, and it will keep doing its job—cleanly, steadily, and without drama.
