The Aries by Fohse

The most powerful and efficient commercial LED grow light the world has ever seen... now re-imagined for the home grow.

640W, 3-spectrum Home Grow LED Grow Light

Introducing the Aries by Fohse, our first fixture offering exclusively for the home grower. You asked and we listened! We started with our A3i model - the most powerful and most efficient grow light the world has ever seen - and we redesigned it to suit the specific needs of the home garden. Every Aries comes with all the setup components you need to start achieving your best harvests to date.

Unrivaled Efficiency

To keep energy costs manageable, you need a fixture that maximizes watt-to-photon conversion. Like its older sibling, the A3i, the Aries operates at a remarkable PPE OF 3.0 - 3.3 μMOL/JOULE depending on what spectrum and brightness you choose with your Fohse Central Control unit.

Make a Friend Out of Heat

Unlike obsolete plasma grow lights the Aries has no ‘Infrared Spike’ in its spectrum, meaning drastically less heat radiating down on your canopy.


Without the IR Spike cooking your upper canopy, you’ll need far less cooling to compensate in order to keep your LSTs in an optimal range.


A reduction in radiative heat and chilled air compensation makes for a much more even temperature throughout your upper to lower canopy.
