1500W Industrial LED Grow Light 

Low Voltage 

*Please Select the Correct Plug Option From the Drop Down

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

Everything Culminates Here...

The A3i is designed to grow and grow. 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.

Unprecedented Canopy Penetration

Early-generation LED lamps failed the industry due to low output + poor canopy penetration. The secret of Aries' success is abundant PAR focused onto your canopy by polycarbonate focal lenses. Next, the Aries LED grow light deploys 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 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 worldwide. What it's 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 growth lamps is a safety hazard. At full power, the A3i is about as hot as a sink full of dishwater.

Dustproof & Watertight

Your growing 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 complete 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.

Easily Integrate With Your Environment

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

Please note that due to the higher shipping costs and larger dimensions of some of our products, our shipping calculator may not always provide an accurate shipping estimate. In these cases, we will reach out to you with an updated shipping quote after you place your order. If you have any questions about shipping costs, please don't hesitate to contact us before placing your order. We apologize for any inconvenience and appreciate your understanding.

Seres reserves the right to notify you of any additional shipping charges. We partner with multiple vendors and locations, which can alter shipping rates. In addition, there are conditions out of our control (rural areas, fuel surcharge, multiple shipments). If this occurs, you will be contacted immediately and have the right to modify or cancel your order for a full refund. 

Address Change / Order Cancellation

If you need to change the shipping address, please get in touch with us at or call 1-877-237-3754

Once the order is shipped, we will do our best to perform an address intercept. You will be charged an Intercept Fee imposed by the shipping carrier. This fee varies from each carrier. Please note not all shipping carriers will accept address intercept changes.

If an order is canceled in transit, you are solely responsible for all shipping charges incurred by the Shipping Carrier.

Shipping charges will not be refunded.


Once an order has been shipped, we will send an email and text message on file with the tracking number. If your order is fulfilled from multiple vendors or locations, you will receive shipment confirmations with tracking for each shipment. 

In addition, you can check the status of your order through the order confirmation email or within your profile page under Track Order.
