FOHSE A3i PRO
The Best Grow Lights in the Market Now Reimagined.
1500W Industrial LED Grow Light. Designed for advanced control capabilities with 7 Channel Spectral Tuning in High Bay Environments. Producing unbelievable yields at greater efficiencies with more control. Our flagship series, now upgraded with advanced controls and unlimited spectral tuning options.
Big Results Cultivated from Small Beginnings
The A3i PRO starts with industry-leading components, from our diodes to our drivers to our optics. Ensuring proven, tested quality built to last.
With Less
Because of its unprecedented power output and industry-leading coverage area, an A3i PRO 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 PRO luminaires and join the growing movement of pioneers setting harvest records under high-intensity lighting environments.

Ultimate Control over Your Lighting Capabilities
The first of its kind, unlock your plants true potential with full spectrum tunability. The A3i PRO has upgraded tunability consisting of 7 isolated spectrum channels including: UVA, green, far red and more providing customizable brightness and spectral output throughout the growth cycle.
Capabilities
Never Buy Another Bulb Again. The Future is Here.
How much would you save if your grow never had to replace another bulb? Maintaining an HPS system is a burden to your bottom line due to:
- Labor costs
- Hazardous waste fees
- Tedious cleaning
- The cost of the bulbs themselves
- The inevitable replacement of worn out ballasts
Over time that burden will far outweigh the low cost of an HPS system. Eliminate the burden entirely by switching to FOHSE LED, the best grow lights for cannabis. Buy right, buy once.
Suddenly. LEDs
slowly fade.
To put the L70 of the A3i PRO into perspective, after 110,000 hours of use the fixture’s output will have diminished to 2,940 μmol/s, which is still 47% MORE POWERFUL than a fresh-out-the-box 1000W DE HPS bulb. That’s 25.1 years of daily use at 12 hours a day.

Revolutionary Heat Control Technology for Commercial LED Grow Lights
Out of Heat
aircraft grade aluminum
Unlike obsolete plasma grow lights the A3i PRO has no massive ‘infrared spike’ hidden on the far ends of its spectrum, meaning drastically less heat radiating down on your canopy.
Efficiency Optimized.
The A3i PRO achieves exceptional photosynthetic photon efficacy, rivaling top LED grow lights worldwide. How? Abundant diodes ensure optimal performance without overclocking, paired with our patented thermal management system.
Smaller Bills?
When you equip your facility with the most powerful AND efficient LED grow light available you have two paths forward. First, configure your A3i PRO to maintain your current light levels at rock bottom prices. Second, maintain your electrical expenditures and produce far more light per watt than you’ve ever seen.
