Includes our FGI three channel color tuning controller. The FGI LIghtpanel 500 represents all we've learned over the years developing lighting for grow. It's such a great grow light we even have our own design patent. 

At 44" long it easily covers a 4' grow tray and up to 5' of mature canopy. Install three over a 4' x' 8' grow area and save 33% energy as compared to a pair of traditional HID grow lamps. Growers report up to 1.9 GPW with this super efficient high yielding light.

Hang this light as close as 12" for deep light penetration through the canopy or raise it as high as 36" to match typical PAR output of a 1000 W HPS lamp leaving plenty of head room to walk below in commercial installations.

Suitable for both full scale commercial growing or home use in tents and small rooms, the Lightpanel 500 will exceed your expectations.

(IMPORTANT NOTE: Please let us know if you'd like a FREE 110V / 220 or 227V plug with your purchase. Item ships with 8' bare whip power cord.)

    Spectrum Overview


    lightpanel light spectrum

    The Lightpanel 700 full spectrum LED uses our patented 50% / 50% mix of warm and cool white LEDs, with added 660nm red for maximum flowering results.

    Our light output is designed to more closely mimic the spectrum of the sun, and is also able to match the McCree Action Spectrum - ideal for boosting photosynthesis in all plant life.

    As compared with Gavita HPS lamps our spectrum is more full, which explains why growers have seen such great results with these lights.
