The FGI Lightpanel 500 V2 is newly powered with the latest 2021 chips. Upgraded diodes create up to 1500 umols of PAR at 15".
Designed in the USA, patented by FGI and made in the US in Spokane, WA, you'll love how this units fits neatly over a 4' wide grow tray or in 4' deep rack shelves.
Suitable for both full scale commercial growing or home use in tents and small rooms, the Lightpanel 500 will exceed your expectations.
Controllable with our V2 Dimming Controller or using Trolmaster with an Adapter F, the Lightpanel 500 has two constant current drivers that dim to OFF. No switches or relays needed.
Our light spectrum recipe is unchanged. We mix an equal number of warm white full spectrum diodes with neutral white Seoul Semiconductor 2835 diodes. These diodes produce 2.25 umols/j which we've found is the sweet spot for price and performance. We then add 36 Cree XLamp 660nm red diodes to push additional red energy to the canopy. And all the diodes have a new conformal coating, a rubberized seal to further protect the diodes from overspray in the grow.
A five year warranty makes this a safe choice in a market filled with pretenders.
This is a true commercial grade LED grow lamp. Designed and produced by Forever Green Indoors. The Plant Lighting Experts.
The FGI 3 Channel Spectrum Tuning Controller allows for a robust fully passive hard wired interface to our bundled FGI Controller. Simple plug and play connections using standard CAT6 network cable.
Adjust warm white diodes, cool white diodes and red channel for spectrum tuning and dimming.
Connect up to 30 meters of our Lightpanel products and have complete control over your spectrum and PPFD at canopy!

FGI Controller Spectrum Tuning Examples
Color tuning your Lightpanel is easy and flexible. Increasing red or decreasing blue has been scientifically proven to change the structure and potency of your plants.
Also available, but not included is our FGI Dimmer Control Module. Choose the controller that best fits your style. (FGI Lightpanel 500 Adapter Cable required).
Spectrum Comparison vs HPS vs the Sun
The Lightpanel 500 V2 full spectrum LED uses our patented 50% / 50% mix of warm and cool white LEDs, with added 660nm red.
In this new version we are using the latest and most efficient diode technology from Seoul Semiconductor. These diodes stack up directly to the popular Samsung LM301 B/H diodes used in our Uniformity Pro 640. However they are more cost competitive. Here is how the two diodes compare in terms of output.
We use the .5 W 2835 (b) diode and use twice as many on our three 14" LED boards totaling 1260 full spectrum neutral white and warm white. Each diode is driven well under its .5 W capacity which leads to a longer lifespan at full light output.
