The perfect light for 2'x2' coverage in flower, the FGI Square 2, introduced in 2020 has an innovative square within a square design. Grow with precision and control with perfect uniformity over the plant canopy. Maximize yield and potency with our full spectrum + red + far red, not found in other LED grow lights.

Great Build Quality. Excellent Spectrum & Light Levels.

Running at only 220 watts the Square 2 runs cool in small grow spaces. Add two or more to increase PAR levels. We've seen growers use 4 of these in a 5'x5' operating at 880 watts with incredible results in flower.


PAR levels at 15" are equal to a 600 watt HPS. At 12" PAR levels exceed 1000W HPS.


What makes the square different? We add both 720NM (far red) diodes as well as 660nm (red) diodes along with 4000K CCT full spectrum.

Our Far Red Boosted Spectrum Maximizes Growth 

Top bin Shenzhen Ledida diodes. Including 6% 720nm infrared plus + 27% 660nm red which growers have found is the key to potent flowers.


The FGI Square 2 has a powerful footprint over a 2'x2' space as shown in this 3'x3' PAR map.


As with all FGI brand grow lights we don't skimp on construction quality. A clear lens protects the diodes from accidental overspray. This compact 20" x 20" unit is lightweight too at just 12 lbs. so it is easy to handle and hang. 


Our lights come with full five year warranties making them the safe long term choice. our 60 day no-hassle return policy means no regrets after unboxing. You'll recognize the quality of our product from the care we take in packaging and shipping.
