Introduction
We built this warehouse heater as a straight swap for those old infrared tubes in high-bay spots. It’s a 400V, 2500W halogen unit, just 300mm long, and it hooks up through a standard R7s connector. So you can drop it in fast. It was designed for one thing: getting that radiant heat out there, fast. Especially in places where the air keeps moving and the ceilings are so high, regular convection heat just can’t cut it.
Technical Deep-Dive
We went with 400V because that’s what most industrial spaces already have. It keeps the current down, which means you don’t need to run heavy, bulky wire. And that 2500W packed into a 300mm tube? That’s a lot of heat in a small footprint. It creates a tight, powerful hot zone—perfect for spot heating. It warms up quickly, which is great, but it also means the fixture and the wiring around it feel the heat. So plan your mounting clearances, and make sure there’s room for the unit to breathe.
Material & Design
Halogen technology keeps the filament running hotter. That means more infrared output, and it stays steady over the life of the tube. The quartz envelope has a special coating. It helps control UV and can handle the shock of turning on and off fast, over and over. The R7s connector makes wiring in the field simple. Slide the tube in, lock the contacts, and you’re done. It’s built to hold steady, even when things are shaking and the temperature is swinging wildly.
Application & Benefits
In warehouses, workshops, and loading bays, this heater puts its energy right where you need it: on people and on the work area. Not into the vast empty air around them. You feel the comfort faster. There are fewer drafts, and the heat feels predictable. Because it’s compact, you can plan out several units to create different zones without tearing into ductwork. Just keep one thing in mind: that high heat density means you need to space the fixtures properly and keep the air moving, so the overall temperature stays under control.
