How Much Light is Too Much?
When you manufacture the most powerful grow light in the world, this is a question we often get. The short answer is your plants will tell you. The deeper answer is, well, it depends on what other factors in your environment are limiting your crop from fully utilizing all available light – watering schedule? Leaf surface temperature? Ambient CO2? Genetics?
For our cannabis clients, the question is actually ‘How much light can cannabis take?’ The answer to that question is, we really don’t know (click the link to listen to Dr. Bruce Bugbee’s thoughts on the matter).
On of our clients in Michigan is really pushing their genetics to find out, and after setting back-to-back, record-breaking harvests all throughout 2020, they still haven’t found the top! Follow this link for a brief summary of their results over 40 harvests.
The Infrared Spike
Ever notice how most spectral charts for grow lights stop around the far-red region? That’s because extending the chart into the infrared region would show one of the biggest problems with plasma-burning light sources… an enormous spike of radiative heat!
Savings Add Up (and so do yields)
Every year the wholesale price for flower and biomass is dropping. What’s more, the global cannabis market is consolidating even before widespread legalization has occured. Top that off with energy restrictions popping up in various markets aroud the world. With this in mind, it’s obvious that any licensed cultivator needs every edge they can get.
We know the biggest barrier to entry with an LED grow light system is the upfront cost. When you break down the operating cost figures as compared to an HPS system, reality sets in – can you afford not to go LED? See for yourself.

PPE & Grow Light Efficiency
You’ll notice we post the efficacy performance of the Aries as a range. These figures represent the top and bottom ends of how well your Aries unit will convert electricity to usable photons. LEDs tend to operate more efficiently when operating below maximum output. The lowest PPE figure is representative of running the Aries at full power in the ‘Spring’ spectrum, while the highest figure is representative of running the Aries at 50% output in the ‘Autumn’ spectrum.
By contrast, our Pleiades model is lower powered with a slim profile designed to line the trusses of your greenhouse. It is best-suited for greenhouses and hoophouses where uniformity and efficacy are the priorities.
At Fohse, we design and build the best grow lights for cannabis on the market for any grow space. Whichever your preference, our team will help you make the right decision.
This is Unprecedented Canopy Penetration
Early generation LED lamps failed the cannabis industry due to low output + poor canopy penetration. The secret of the Aries’ success starts with abundant PAR focused onto your canopy by polycarbonate focal lenses. Next, the Aries LED grow light delpoys 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
Buy right, buy once.
L90:
40,000 hours
(Based on diode manufacturer specs)
Bulbs Die Suddenly. LEDs slowly fade.
Our L90 and L70 figures come straight from the data sheets and stress-testing provided by our diode manufacturers. To put the L90 of the Aries into perspective, after 50,000 hours of use the fixture’s output will have diminished to 1,613 μmol/s, which is still better than the output of every other LED grow light in the same class as the Aries. And just how long is 50,000 hours? If you run 12/12 cycles every day that’s 4,166 days … 595 weeks … 136 months … 11.4 years of runtime and your system will still outperform every other comparable LED grow light out there. (and of course all those bulb changes you’ve eliminated)

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
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.
