Fohse A3i, the Best Grow Lights in the Market

Because of its unprecedented power output and industry-leading coverage area, an A3i system will always require less fixtures to produce similar (or better) light levels as an HPS system or LED system of similar size. Depending on your goals you can opt to use less fixtures to produce the light levels you’re accustomed to, or you can ‘fill the grid’ with A3i luminaires and join the growing movement of pioneers setting harvest records under high-intensity lighting environments.

If there's one thing we've learned touring close to a thousand cultivation facilities around the world, it's that every environment is unique with its own special requirements. When you work with Fohse, our partnership kicks off with a thourough review of your grow room plans and your goals. Our light planning team heads into our simulation software to develop a 100% custom configuration tailor-fit to the unique needs of your operation. We can even take it a step further and predict your cost of cooling, cost of electricity, and how much you'll save owing an A3i system over time.

To put the L70 of the A3i into perspective, after 110,000 hours of use the fixture's output will have diminished to 2,940 umol/s, which is still 47% MORE POWERFUL than a fresh-out-the-box 1000W DE HPS bulb. And just how long is 110,000 hours? If you run 12/12 cycles every day that's 9,166 days ... 1,309 weeks ... 301 months ... 25.1 years of runtime and your system will still outperform an HPS system.

Unlike obsolete plasma grow lights the A3i has no massive 'infrared spike' hidden on the far ends of its spectrum, meaning drastically less heat radiating down on your canopy.

Less AC

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.

Even Warmth

A reduction in radiative heat and chilled air compensation makes for a much more even LST temperature throughout your upper to lower canopy.

More Bud Growth

An even canopy LST temperature promotes more RuBisCO reactions down your canopy, leading to more instra-canopy bud development.

More Cannabinoids

Cannabinoids are heat-sensitive. No more destructive IR spike means more cannabinoids make it to harvest.

More Terpenes

Terpenes are also heat-sensitive compounds and degrade at higher temperatures. Enjoy some of your best terp profiles ever with the A3i!

Higher Harvest Quality

More cannabinoids and better terpene profiles means you'll enjoy some of your best harvests yet with the A3i.

When you equip your facility with the most powerful AND efficient LED grow light available you have two paths forward available. First, you can configure your A3i system to maintain the light levels you’re used to, and thanks to the A3i's top-rated efficacy you'll produce that light at rockbottom prices. Second, you can configure your A3i system to maintain the electrical expenditures you’re used to, and with the A3i’s sky high efficacy that means you’ll produce far more light per watt than you’ve ever seen. Just wait and see what’s possible win a high-intensity light environment. Click here for a glimpse.

How does the A3i generate so much power yet remain relatively cool to the touch? The secret is in the engineering advantage harnessing the principles of conductive and convective heat transfer. We’ve packed over 16,000-in² of surface area into the A3i’s custom heat sinks. This effectively dilutes and disippates any heat across all that surface area via conductive heat transfer. This makes it much easier for the normal ambient airflow to wick that heat away from the fixture via convective heat transfer where it can be easily shuttled out of your grow environment.
