The A3i Industrial LED Grow Light from Fohse

The most powerful grow light in the world, period. The 1500w Fohse A3i is designed for unbelievable yields. One 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.

Ideal plot 5' x 5' to 6' x 6'

Early LED lights could not produce results that were on par with their HID competitors. However, LEDs have taken incredible strides in recent years and now outpreform HIDs on a regular basis. 

Never Buy Another Bulb Again

How much would you save if your grow never had to replace another bulb? Between hazardous waste, frequent bulb replacement, worn out ballasts, and labor costs, maintaining a HID system is a burden. That burden will far outweigh the cheap cost of an HID system over time. Buy right, buy once.

Unrivaled Efficacy

The A3i is capable of some of the best photosynthetic photon efficacy figures of any LED grow light in the world.  It is impervious to dust, mites, aphids, and spores. It can even withstand full submersion in 1 meter of water.

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.

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.

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.

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.

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.

Power Surges? You're Ready. 

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

This is why Umami prefers LEDs over HIDs:

• LEDs use less electricity and are more energy efficient

HIDs produce less light and require more power to run than LEDs. 

• LEDs are cheaper to operate

Our LEDs cost up to 80% less to run than equivalent HID bulbs.

• LEDs produce significantly less heat

Plants are sensitive to heat and do very poorly in temperatures above 85 degrees fahrenheit.

• Most HID grows require a lot more AC to cool down
  

LED's are substantially better at keeping temps in your ideal range and can reduce AC costs by 30-40%.

• LEDs output more light

The unit usede to measure light in the canopy is PPFD. LEDs are able to to put off a higher total PPFD than HID lights and LEDs even use less electricity doing it.

• HIDs are a fire risk

HID lights get extremely hot and have the potential to start a fire in your room. There are countless facilities that have burned down due to HID light fires. 

• LED's don't have toxic elements

HID lights are filled with toxic gas and metal. If HIDs burst they can contanimate huge areas. LED's do not have any of these toxic elements.

• HID's need to get expensive bulbs replaced

HID's constantly need to have their bulbs replaced. This is not only a labor intensive process that delays your progress, it is also very expensive

• LEDs last longer

HID bulbs need to be changed frequently. LED lights can run 24/7/365 for years and years without ever having to be maintainted.

• LEDs continue to become more affordable

LEDs continue to get cheaper and cheaper while the technology within them gets better and better. 

• LEDs allow for light spectrum manipulation

With and LED you can give the plants the perfect amount of light. The result is a higher yield.
