The FLW800 is the first true 1 for 1 LED replacement for the HPS 1000w horticultural light. The FLW800 puts out 1936 µmol of photosynthetic light using only 800 watts. This is the highest output of ANY LED fixture on the market. 


We employ Samsung 301H "white" LEDs because they are the most efficacious and economical LEDs available today at 220 lm/w and 2+ µmol/j. By delivering a full spectrum white, our lights can penetrate deeper into the plant matter due to higher levels of green. The 6000k diodes have a strong blue outpu,t 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 for growing plants. They are extremely efficient, but are also very expensive. The FLW800 uses 90% Deep Red 660nm and 10% Far Red 730nm wavelengths. This Red/ Far Red ratio is very important for horticulture. Both channels are addressable/ dimmable individually or together for different plant response targeting strategies such as resetting, flower initiation, and shade avoidance. Running the light as designed increases the rate of photosynthesis through the Emerson Effect.


The FLW800 gives you the power and control to deliver the highest quality light to your plants for 50,000 hours.


It's the most dependable horticultural flowering fixture available today.
