All New for 2021 our FGI Lightpanel 500 V2 Commercial Grade LED Light For Bloom

All New for 2021 our FGI Lightpanel 500 V2 Commercial Grade LED Light For Bloom


Regular price $ 1,149.00 $ 995.00 Sale

For a limited time we are including our 3 channel spectrum tuner for FGI Lightpanel 500 LEDs, free with each order. A $199 value! Limited to stock on hand. 

The FGI Lightpanel 500 V2 is all new. Upgraded LED diodes push 1000 umols of total PPF using just 450 watts of input power. 

Made right here in the USA, 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.

      Spectrum Comparison vs HPS vs the Sun


      lightpanel light spectrum

      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.
