Technical Deep-Dive: Power and Electrical Specs
Let’s talk power. These greenhouse heaters are built as high-output halogen infrared units. They run on 400V and pump out 2500W. Why 400V? It keeps the current draw low, even when you’re running long cables. That means less voltage drop along the line. The tube is just 300mm long, which packs all that 2500W into a small footprint. You get serious heat density exactly where you need it. And it’s direct heating—energy goes straight to plants and floors, not into warming the air.
Material and Design: Why Coating and R7s Matter
The quartz tube is filled with halogen and often coated to tweak the output spectrum. That coating helps shape the infrared so plants and surfaces absorb it better. Then there’s the R7s double-ended connector. It’s practical, reliable, and makes the lamp a simple drop-in replacement. The build can handle rapid heating and cooling, but keep this in mind: the hot end gets intense. Give it proper mounting clearance.
Application and Engineering Benefits
In a greenhouse, you want steady zone control without pushing your electrical system too hard. These heaters deliver fast, directional warmth that cuts down cold spots and helps you hold your target temperature. Installation? Straightforward. Wire it up, point the beam where you want it, and set the distance. One trade-off: that concentrated output means you need good ventilation and heat management nearby. You can count on consistent performance—just keep flammable materials well clear of the beam.
