Halogen IR Heat Lamps: The Greenhouse Warmth You Can Actually Control
We built these halogen infrared lamps for one simple reason: to give your greenhouse the kind of heat that hits right where you need it. Instead of washing your plants in broad-spectrum light, these focus straight on the infrared. The heat goes directly into stems, soil, and roots—without wasting energy on visible light.
Power, voltage, and size—made to fit real greenhouses
These lamps are designed to play nice in industrial greenhouse setups. They run on higher-voltage configurations—often 400V—which means lower current. That lets you keep wiring thinner and prevents voltage from dropping off over long cable runs. And the wattage? It’s packed into a small footprint. A common setup is 2500W in a 300mm tube. That short, dense design concentrates the IR field, so you get intense heat in a tight zone.
What’s inside: halogen chemistry, quartz, and a solid connection
The heart of it is a halogen-filled quartz envelope. The halogen chemistry helps keep the filament stable and slows down that annoying blackening over time, so output stays steady through the lamp’s life. Quartz handles quick temperature swings and lets infrared pass through efficiently. Then there’s the R7s connector—double-ended, direct-wire, built to take high heat at the ends and give you a secure, low-resistance electrical fit. Installation is straightforward: line up the pins, seat the lamp, and it locks in.
Why greenhouse growers actually use these
In a greenhouse, what you really want is steady warmth under the canopy—especially for germination, root development, and protection on cold nights. Infrared heat penetrates plant tissue better than convection heat, which helps reduce temperature stratification and keeps the growing zone more even. And if your place already uses R7s sockets, these lamps drop right in. No reworking fixtures. Just swap and go.
The honest catch
Let’s be real: a 2500W lamp in a 300mm tube runs hot. That heat is exactly why it works, but it also means you need proper thermal management. Make sure your fixture, reflector, and ventilation are up to the job.
Why this setup stays predictable
Halogen IR gives you output that’s consistent and spectrally stable, which makes control loops easier to tune. And if your greenhouse layout already has R7s sockets, you can replace lamps fast—minimal downtime.
The bottom line, without the fluff
If your greenhouse needs focused heat where it counts, a halogen IR lamp with 400V operation, 2500W output, and a 300mm tube gives you that—plus the durability and mounting compatibility to keep running, day after day.
