Fohse Pleiades 320W Greenhouse LED Grow Lights

Slim Profile. Seamless Integration.
The ideal supplemental greenhouse grow light should be just that -- supplemental. We designed the Pleiades with a slim profile for seamless installation along the existing truss infrastructure in your greenhouse. This seamless integration casts no additional shadows, making it the perfect supplemental light source for your greenhouse.

Ultimate Uniformity
The Pleiades is designed around the idea that there is strength in numbers. Every fixture in a full Pleiades system works together to deliver best-in-class light uniformity with less than a 10% variance in PPFD levels. Consistent harvests begin with consistent light levels, and the Pleiades is the right tool for the job

Automated Light Response
Every Pleiades system is bundled with ‘Light Harvesting’ sensors that measure the natural light in your greenhouse. Cloud cover? Seasonal daylight fluctuations? The Pleiades with Light-Harvesting can self-adjust in increments of as little as 1% in real time based on the ever-changing light conditions in your greenhouse.

A Fixture to Last a Lifetime.
It’s no secret that LEDs last significantly longer than legacy HID systems. In a Pleiades greenhouse with Light-Harvesting technology, the effect of this truth is compounded considerably. By running the fixtures only when and as much as needed, the lifespan of your Pleiades system is generational. Buy right. Buy once.

Cool Diodes are Efficient Diodes.
Heat, improperly managed, is an efficiency killer. The Fohse engineering team has run hundreds of hours of thermal analysis across many design iterrations of the Pleiades. The design you see here is the best of the best of all those iterations. The result? Efficient photon emission with rock-bottom energy consumption.

Made for Damp Environments
Any controlled cultivation environment is susceptible to the rigors of fluctuating humidity. That humidity can be a serious risk to sensitive electronics, especially in greenhouses where humidity can turn into condensation and condensation into drips. We built the Pleiades to achieve an IP55 rating, which means drips will never be a problem. In fact, with an IP55 rating, you can hose your fixtures down post-harvest without ever taking them down. That’s a real time saver.

Easily Integrate
Turning your greenhouse into a state-of-the-art LED grow operation is fast work with the Pleiades. Easy-to-install truss brackets make installation a breeze. Additionally, the ability to daisy-chain power between multiple fixtures means no overhaul of your existing electrical infrastructure. This means that soon after you receive your Pleiades system, you’ll be growing in no time!

Seeing Is Believing.
Other light brands boast about being the best. We won’t just tell you we’re the best.
We’ll prove it. Better yet, we’ll let our customers do the talking.

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.

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.
