How did we do it? Most lights spread the LED diodes over a large area to maximize uniformity and many were designed to top out at 1000 umols of PPFD at about 12" from canopy.
The FGI Lightpanel 500 V2 takes a radically different approach.
This unit was designed with three side by side panels set with 2835 individual warm/neutral white LED diodes spaced in close proximity across each board.
Three separate drivers control three separate diode colors (color tuning is optional too).
The result is massive full spectrum PPFD output across every square inch. We then surround each 14" panel with 660nm red diodes to give the flower phase an extra kick.
This light is no pretender and is not imported from overseas. All American USA made and it shows. Designed in the USA, patented by FGI and made in Spokane, WA, you'll love how this units fits neatly over a 4' wide grow tray or in 4' deep rack shelves.
