Fohse A3i 1500W Industrial LED Grow Light

The most powerful grow lights in the world

Designed for unbelievable yields in high bay, single level environments. The power of A3i starts with thousands of diodes from industry leading diode manufacturers.

Unprecedented Canopy Penetration
Early generation LED lamps failed the indoor growing industry due to low output + poor canopy penetration. The secret of the Aries’ success starts with abundant PAR focused onto your canopy by polycarbonate focal lenses. Next, the Aries LED grow light delpoys an advantage you won’t find anywhere else—swiveling light bars to achieve maximum canopy penetration by cross illumination to neighboring grow plots.

Never Buy Another Bulb Again
How much would you save if your grow never had to replace another bulb? Between labor 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. Buy right, buy once.

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.

Unrivaled Efficacy
The A3i is capable of some of the best photosynthetic photon efficacy figures of any LED grow light in the world. Its 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 dish water.

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 grow. It’s impervious to hitchhikers (dust, mites, aphids, spores). It can even withstand full submersion in 1 meter of water.

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

Everything Culminates Here…
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.
