The A3i model, a 1500-watt industrial LED light, is designed for high-bay, single-level environments and is built to withstand intense grow conditions from “hitchhikers” such as mites and aphids to full submersion in a meter of water. Made with diodes from industry-leading diode manufacturers, the A3i is Fohse’s answer to the low output and poor canopy penetration of the cannabis industry’s early-generation LED systems, with swivelling light bars to achieve maximum canopy penetration via cross illumination to neighbouring grow plots. Models of the A3i provide between 50,000 and 110,000 hours of light up to 12 years’ worth.

When it comes to heat management which can be a costly process for HPS users A3i produces 60 per cent more light per BTU than an HPS system. The A3i also boasts some of the highest photosynthetic photon efficiency levels of any LED grow light worldwide, with an abundance of diodes to prevent any diode from becoming “overclocked.” The system is safety-conscious as well, with an average surface temperature of 115 degrees Fahrenheit approximately the temperature of a sink full of dishwater at full heat and three layers of protection against electrical overload scenarios.

Designed for unbelievable yields in high bay, single-level environments.

SUPPLEMENT CO2

• The power of A3i starts with thousands of diodes from industry-leading diode manufacturers.

This is Unprecedented Canopy Penetration

• Early generation LEDs failed the cannabis industry due to low output + poor canopy penetration. The A3i is the most powerful grow light in the world. Swivelling light bars achieve maximum canopy penetration via cross illumination to neighbouring grow plots.

Never Buy Another Bulb Again

• How much would you save if your grow never had to replace another bulb? Between labour costs, hazardous waste fees, tedious cleaning, the cost of the bulbs themselves, and the inevitable replacement of worn-out ballasts, maintaining an HPS system is a burden to your bottom line. Over time that burden will far outweigh the low cost of an HPS system. Eliminate the burden entirely by switching to Fohse LED.

Innovative Heat Management

• Cooling a traditional HPS setup can be costly, especially when putting more light into the environment. The A3i produces 60% more light per BTU than an HPS system, significantly reducing the strain on your cooling systems.

Unrivalled Efficacy

• The A3i is capable of some of the best photosynthetic photon efficacy figures of any LED grow light in the world. Is it's secret? An abundance of diodes so no diode is 'overclocked', as well as our patent-pending thermal management. Cool diodes are efficient diodes.

Safe to Handle. No More Burns

• It's no secret that the heat from typical HPS grow lamps is a safety hazard. At full power, the A3i is about as hot as a sink full of dishwater.

Dustproof. Watertight.

• Your grow environment isn’t the friendliest place for sensitive electronics. That’s why the A3i can withstand the intense conditions of your growth. It’s impervious to hitchhikers (dust, mites, aphids, spores). It can even withstand full submersion in 1 meter of water.

Power Surges? We're Ready

• The A3i comes twice protected from electrical overload scenarios. Thrice-protected if you count our 5-year conditional warranty.

Everything Culminates Here

• The A3i is designed to grow cannabis. Its spectral distribution output is tailored to suit the unique demands of the plant. Easily switch between spring, summer, and autumn modes as your crops mature through their life cycle.

Easily Integrate With Your Environment

• Installation is simple and the learning curve with high-quality LED is short. If you've never cultivated under high-intensity light levels, we have a long list of cultivation experts who have had success with our fixtures standing by to coach you and your team to incredible harvests.
