499mm 277V 1600W R7S Halogen Infrared Heat Lamp: Built for Heat, Right Now

We built this lamp for the moments when you need heat—fast. No waiting. No lag. Just immediate, focused warmth, packed into a compact space. If your industrial process needs that kind of punch, this is your workhorse.

Power, Voltage, and Shape—Why It Matters

Here’s the thing: this lamp runs at 1600W and 277V, which lines up perfectly with the voltage you’ll find in most industrial setups. That means you can keep wiring runs shorter and avoid the headache of voltage drop you’d get trying to push the same wattage at 120V. And that 499mm length? It concentrates the heat into a tight zone. You get a sharp, focused hot spot, exactly where you need it. That shape also lets you use a smaller reflector and still hit your target temperature on the part.

Introduction

We see a lot of interest in swapping out legacy linear tungsten halogen lamps for LED-based R7s replacements. The goal is straightforward: keep the same footprint and mounting, but get better control and lower operating costs. However, you cannot just wire an LED module into a halogen fixture and expect it to behave the same. The physics of heat generation and the electrical constraints are fundamentally different.

Technical Deep-Dive: Power, Voltage, and Dimensions

Linear tungsten halogen lamps are designed to run hot—typically 2500W to 3000W at 230V or 400V, in tube lengths around 300mm to 350mm. This power density is what gives you the rapid temperature ramp-up needed for industrial heating, curing, or shrinking. When you replace these with an LED R7s unit, the LED driver must handle the input voltage and deliver stable power, while the LEDs themselves convert electricity into light, not bulk heat. A 400V input rating on an R7s LED replacement is not arbitrary. It allows direct connection into high-voltage heating circuits without extra step-down transformers, which simplifies the wiring and reduces cabinet heat. But here is the trade-off: an LED replacement that specs out at 2500W equivalent may only draw a fraction of that actual power, so the total heat output is lower. That is good for energy draw, but you have to verify your process actually needs the lower heat flux. If your process relies on high-intensity infrared heat to penetrate a material, an LED replacement may require retuning cycle times or increasing dwell time.
