We built this greenhouse heater to be a straight-up swap for your old halogen infrared tube—no fuss, just power when you need it. It runs on 400V and cranks out 2500W, so the heat comes on fast. You feel that right away: the space warms up quickly, and you get precise control exactly where you need it. Here’s the thing about the 400V, 2500W setup: it pushes serious current through a compact quartz tube, so you get a lot of heat in a small footprint. The 300mm length keeps the warmth focused where it counts, so you’re not wasting energy heating empty air. This isn’t a low-voltage bulb that barely whispers—plan your wiring and controls to match that punch. The quartz tube is coated to shape the output spectrum and shield the filament from the shock of rapid heating and cooling. The halogen cycle keeps the filament stable, so the output stays steady over time instead of fading early. And the R7s connector? It’s an industrial, no-nonsense fit that locks in fast and carries the current without getting hot at the ends. In the greenhouse, this heater delivers targeted infrared warmth that reaches plants and soil directly, helping you hold your setpoints when the cold snaps hit. It’s a drop-in replacement for existing R7s fixtures, so swapping it out is quick—you can get back online without dragging the job out. Just keep one point in mind: that 2500W density means you need proper cooling and the right fusing. Make sure you’ve got the panel space and airflow sorted before you start wiring.
