The GNH600 is designed to fit under the framing of your greenhouse and deliver big light with little shadowing. Using optics specifically designed for your greenhouse mounting height, we deliver uniform light to your canopy and your lighting levels are guarenteed for 5 years!


We employ Samsung 301H "white" LEDs because they are the most efficient and economical LEDs available today. By delivering a full spectrum white, our lights can penetrate deeper in the canopy due to higher levels of green. The 6000k diodes have a strong blue output and are a great match with the Osram Oslon Square Far Red and Deep Red LEDs. 


Osram Oslon Square horticultural diodes are the best choice available today for growing plants. They are the most efficacious, but are also very expensive. The FLW900 uses 90% Deep Red 660nm and 10% Far Red 730nm wavelengths. This Red/ Far Red ratio is very important for horticulture. Both channels are individually addressable and dimmable and can be used for different plant response targeting strategies such as resetting, flower initiation, and night interuption. Horticultural science tells us running the light with full Red and Far Red increases the rate of photosynthesis through the Emerson Effect.


Our lights communicate with your existing greenhouse controls or we can design a control system with you to best suit your needs. You will be able to monitor your lighting levels over their lifetime from your central controls CPU or a phone, tablet, or computer.


These are the most dependable greenhouse fixtures in the world.
