Fohse A3i Designed for unbelievable yields

Fohse A3i

Designed for unbelievable yields.
Patent Pending.

The output of two A3is is equal to the output of three 1000W DE HPS lamps
PPF PPF: “photosynthetic photon flux” — a measurement of the total amount of PAR emitted by a grow lamp every second. 4,529 μmol/s
Accomplish more with less.

An A3i system will require half the number of fixtures to produce the same amount of light as an HPS system. In other words, the coverage of one A3i will still produce more light than two 1000W DE HPS lamps.

Big things have small beginnings

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

Light Plan

When we build you a light plan we start with your preferred average PPFD. We then work backwards to determine how many fixtures are required to meet your preferance. We can even predict your cost of cooling and how much you’ll save owning an A3i system over time. Get your custom plan here.

This Is Unprecedented
Canopy Penetration.

Early generation LED lamps failed the cannabis industry due to low output + poor canopy penetration. The secret of the A3i's success is abundant

A3i LED Longevity
Bulbs die suddenly. LEDs fade away.

You can use your A3i on 12/12 cycles every day for more than 25 years and it will still be 58% more powerful than a fresh-out-of-the-box 1000W DE HPS bulb.

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, and the cost of the bulbs themselves, maintaining an HPS system is a burden to your bottom line. Eliminate the burden entirely by switching to Fohse LED.

Cheaper & better

If you rely on your HPS lamps to keep your crop warm you’re paying a premium for heat. It’s much cheaper to keep your plants warm with a central furnace. Food for thought.

Innovative Heat Management.

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

PPE PPE : “photosynthetic photon efficacy” — a measurement of how efficient a grow lamp is at converting electricity to PAR. The higher the number, the more efficient the fixture and the less you’ll pay for light.

Make Light. Not Heat.

By keeping the diodes in the A3i operating at an optimal temperature the fixture is capable of one of the highest efficacies of any grow lamp.

Safe To Handle. No More Burns.

It’s no secret that the heat from typical grow lamps is a safety hazard.
At full power the A3i is about as hot as a sink full of dish water.

Fohse A3i is impervious to dust, mites, spores, and can withstand full submersion in 3 meters of water
IP67 Ingress Protection Rating

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 dust, mites, aphids, and spores. It can even withstand full submersion in 1 meter of water.

Wavelength Use

Cannabis uses all wavelengths between 350nm - 780nm for photosynthesis and photomorphogenesis with less attention towards greens, yellows, and yellowy-oranges. If a lamp emits too much of these wavelengths or too much infrared light, the extra energy is converted to heat. More work for your cooling system.

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 growth cycle.
