Fohse O6i 1200W LED

Re-imagining Greenhouse illumination

Compact Size, Significant Output

Central to your crop’s success is the idea that greater photon density leads to more carbon assimilation, which means more biomass. The O6i packs more photons into each footprint with a spectral distribution ideal for growing thick, lush canopies.

Greenhouse Toplighting Methods

Not every greenhouse is created equal, which is why Fohse developed two distinct models for greenhouse illumination. With the O6i model you’ll be able to achieve the highest amount of supplemental light, cast the widest footprint, and do so with fewer fixtures. By contrast, the Pleiades model is lower powered with a slim profile designed to line the trusses of your greenhouse. It is best-suited for greenhouses and hoophouses where uniformity and efficacy are the priorities. Whichever your preference, our team will help you make the right decision.

Precision Photon Density

The O6i is designed to be the easiest way to transition an HPS greenhouse system to LED without overhauling your existing electrical or truss infrastructure. So why make the change? 50% greater output than a 1000W DE HPS. 42% greater efficacy. No infrared spike generating unnecessary heat.

Automated Light Response

An O6i system is bundled with 'Light Harvesting' sensors that measure the natural light in your greenhouse. Cloud cover? Seasonal daylight fluctuations? The O6i with Light Harvesting can self-adjust in increments as little as 1% in real time based on the ever-changing light conditions in your greenhouse.

DLI Planning

In greenhouse environments your primary light source is an ever changing variable, so meeting your light intensity and consistency needs comes down to proper Daily Light Integral (DLI) planning from the start.

Say you want to maintain a PPFD of 1,000 μmol/ms2 throughout the year and you’re running a 12-hour photoperiod. Here’s the math to convert that to DLI:
1,000 μmol/m2s × 60 s/min × 60 min/hr × 12 hr/day43.2 mol/m2day
1,000,000 μmol/mol

The Last Fixture Purchase You'll Make

It’s no secret that LEDs last significantly longer than legacy HID systems. In an O6i greenhouse with Light Harvesting technology the effect of this truth is compounded considerably. By running the fixtures only when and as much as needed, the lifespan of your O6i system is generational.

Bulbs Die Suddenly, LEDs Fade Away

Fohse's L90 and L70 figures come straight from the data sheets and stress-testing provided by our diode manufacturers. Predicting the PPF degradation of your O6i luminaires is as simple as dividing the L-figures by the number of hours of daily use. If you were to run your O6i fixtures at full power for 12 hours a day you can reasonably expect its PPF to reduce by 30% over the course of 25 years. But this is only part of the picture. In practical use, you’ll rarely (if ever) run your O6i system at full power. Sometimes you won’t even run it at all.

Cool Diodes Are Efficient Diodes

That’s the secret to packing so much power into each footprint. Aircraft-grade aluminum heat sinks and two hyper-efficient variable speed fans keep the O6i’s LEDs operating at peak efficiency.

Make a Friend Out of Heat

There’s no way around it: the ‘infrared spike’ with HID grow lights is damaging to your crop. While harm reduction methods do exists, you can eliminate it entirely by switching to the 06i by Fohse.


Without the IR Spike cooking your upper canopy you'll need far less cooling to compensate in order to keep your LSTs in an optimal range

Made for Damp Environments

Any controlled cultivation environment is susceptible to the rigors of fluctuating humidity. That humidity can be a serious risk to sensitive electronics, especially in greenhouses where humidity can turn into condensation and condensation into drips. We built the O6i to achieve an IP67 rating, which means drips will never be a problem. In fact, with an IP67 rating you can hose your fixtures down post-harvest without ever taking them down. That’s a real time saver.

Ingress Protection

Ingress Protection testing really puts Fohse fixtures through the ringer - sandblasting, water spray, pressure washing, submersion, etc. Rest assured your A3i is well-protected from the hazards of your grow environment.

Easily Integrated with Your Environment

One of the primary intentions with the O6i design was to make the experience of transitioning to LED grow lights as seamless as possible for greenhouses that currently use HID systems. If all you have to do is plug-and-play, it doesn’t get much more seamless than that.
