Unrivaled Efficiency
Efficacy Comparisons
Aries: PPE = 3.0 μmol/J (up to 3.3 μmol/J)
1000W DE HPS: PPE = 1.8 μmol/J
Popular LED brand: PPE = 2.7 μmol/J

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 PPE: “Photosynthetic Photon Efficacy” - a measurement (expressed as μmol/J) of how efficient a grow light is at converting electricity to PAR. Higher numbers equal greater efficiency. Lower numbers equal lower efficiency with more electricity being converted to heat and/or unusable light wavelenghts. 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.

? WHAT IS THE "INFRARED SPIKE"? WHAT IS THE "INFRARED SPIKE"?
Make a Friend Out of Heat
Swiveling heatsinks for custom footprints & lateral illumination
LESS A/C

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.

Sunrise, sunset, and manual dimming
EVEN WARMTH

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

Sunrise, sunset, and manual dimming
MORE BUD GROWTH

An even canopy temperature promotes more RuBisCO reactions down your canopy, leading to more intra-canopy bud development.

CAT5 Ethernet connectivity for one-touch adjustments
MORE CANNABINOIDS

Cannabinoids are heat-sensitive. No more destructive IR Spike means more cannabinoids make it to harvest!

L6-20 twist-lock plug (alternative options available)
MORE TERPENES

Terpenes are also heat-sensitive compounds and degrade at higher temperatures. Enjoy some of your best terp profiles ever with the Aries!

HIGHER HARVEST QUALITY

More cannabinoids and better terpene profiles means you’ll enjoy some of your best harvests yet with the Aries.

Frequently Asked Questions

  • My Aries fixture isn't functioning properly. What should I do?

    First try the old standby: disconnected both the Aries and the Central Controller from power, and then reconnect and power back up. If that does not correct the issue, open the chat helper and indicate you’d like to open a support ticket. Our technicians will respond within 24 business hours to assist you.

  • What is the light footprint?

    The Aries LED grow light is best suited for a standard 4×4 plot. Feel free to use your favorite PPFD meter to play around with the fixture’s swiveling light bars to come up with your own custom footprints.

  • What is the recommended height / canopy distance?

    We recommend finishing your flower 3-feet away from the fixture at full power on the ‘Autumn’ spectrum setting, but this variable is strain-specific and also influenced on the rest of your environment parameters (grow medium, watering method, nutrient delivery method, cooling capability, etc). The Aries was designed to give you control over your light levels without ever having to adjust the height throughout your grow cycle, but at the end of the day we recommend using your favorite PPFD meter to dial in your perfect height.

  • Can the Aries be used in a vertical setting?

    It sure can. You can use your Central Control unit to set light levels anywhere between 30% and 100% output. Using your preferred PPFD meter you’ll be able to dial in the perfect light level to suit your vertical environment.

  • What is the plug type?

    Type B, 3-pin plug. If you live in a part of the world with different socket types, we recommend picking up a plug converter from your local hardware store.

  • Can it go in a 4x4 tent?

    Absolutely! In fact, we recommend reflective walls for any size grow plot to help reduce the light-dissipating effect of the Inverse Square Law

  • How many diodes are there?

    2,816 on the nose.

  • What voltage can the Aries run on?

    The current configuration of the Aries is made to operate on standard 110V. It can be ran up to 277V, but that would require a DIY swap for a different plug which would void the fixture’s warranty.

  • How many amps does it use?

    5.82 Amps. (640W ÷ 110V = 5.82 Amps)

  • How should I hang the fixture?

    Hanging instructions and hardware are included with each Aries. You can download the instructions here, too.

  • How do I clean my Aries fixture?

    We recommend spraying the your fixtures down with a 2% bleach-water solution and then rinsing down with a hose. The fixture is certified IP67 so rest assured it will be safe from any water intrusion following this cleaning protocol.

  • How many Aries fixtures can I link to my Central Control unit?

    Up to 100.

  • Does the Aries get hot?

    No hotter than a sinkfull of hot dishwater.

  • Is the Aries passively cooled or actively cooled with a fan?

    The form factor of the Aries will passively dissipate heat over thousands of square inches of surface area where it can easily be wicked away by your environment’s fans.

  • What is umol/J and why does it matter?

    It reads “micromoles per Joule” and is a measurement of how efficient a grow light is at converting watts to PAR photons, or its “photosynthetic photon efficacy” (PPE). Many shady manufacturers will mislead you by saying their light is capable of high PPE figures, but will leave out the fact they load the fixture up with red diodes which are more efficient than white or blue. The Aries is currently the most efficient grow light out there with a Balanced Spectrum optimal for horticulture.

  • Do you sell/ship to my country?

    We currently ship all over the world.

  • What is your return policy?

    Our 3-year warranty covers manufacturing defects. Since grow lights depreciate with use, we cannot accept returns for any other reason. If you need to inquire about a warranty claim, please open the chat helper and indicate you’d like to open a support ticket. Our technicians will respond within 24 business hours to assist you.

  • How can I sign up to distribute Fohse products?

    We’re always looking for partners around the world to carry our state-of-the-art LED grow lights. Please fill out our contact form and indicate you are a distributor. A member from the Fohse team will respond within 24 business hours to assist you.

  • Why are some of the leaves on my plants twisting or bleaching?

    This could be a sign that your Aries is powered up too high. Try dimming the light seeing if that corrects the issue. If not, you may have other issues to investigate such as watering or nutrient protocols.

  • Should I wear protective glasses when working under my Aries?

    Yes, basic sunglasses will work. The Aries is bright and frequent, repeated exposure without protection will strain your eyes.

  • Is it true that growing with LEDs requires slightly higher room temps than HID setups?

    In most cases, absolutely. HID bulbs have a huge spike in the infrared range (manufacturers conveniently stop their spectrum charts short of the IR range) that is traditionally handled with lower room temps. The Aries does not have this inefficiency, so you’ll be able to dial back the cooling and let your room temp rise. We recommend using your preferred thermographic camera or similar instrument to ensure your leaf surface temperature (LST) is around the 82-85°F range. Any lower and photosynthesis will slow down.

  • After a power outage will my Aries come back on?

    Once power comes back on the Aries will return to whatever state it was in prior to the power outage.

  • Should I use a surge protector with my Aries?

    The Aries has two internal surge protection and line filter circuits already included inside so no surge protector is needed.
