DESCRIPTION

The FGI 385nm UV LED Lightbar is designed to provide targeted supplemental blue energy to equal natural sunlight levels. At Forever Green we strive to match natural sunlight with our lighting products. 

Recent studies at Utah State University by Dr. Bruce Bugbee have shown that plants absorb and benefit from light between 380-740NM. This research has led to the study of E-PAR or extended PAR and is redefining measurement of photosynthetic light. 

Below are the spectrum charts which compare natural sunlight to full spectrum LEDs and then to full spectrum plus supplemental UV. 

The result is a closer match to sunlight providing more of the beneficial blue light that plants benefit from. 


Sunlight Levels of 380NM UV

Natural sunlight provides plants 1.22 umols of 380nm blue energy. 

Natural Sunlight Spectrum Blue Energy 1.2234 umols


Typical Full Spectrum LED Lack 380NM UV

Full spectrum LEDs have limited blue spectrum which peak at 460nm.  

Full Spectrum LED 460nm Blue Energy Levels .0514 umols


Full Spectrum LED with Supplemental 380NM UV 

Adding supplemental 385NM UV creates a secondary peak of blue energy at 1.5047 umols at 12" from the canopy, roughly equaling natural sunlight. 

UV spectrum

Supplemental UV Spectrum plus Full Spectrum Blue Energy 1.5047 umols (3x greater) 

Build Quality

These are high quality units with a crystal glass lens cover to protect the diodes and allow for cleaning. The all aluminum frame dissipates what little heat the bar creates. At 30 watts the Lightbar sips energy too. 

Spectrum Theory 

Blue energy is scientifically known to help form more compact plants. More lush leaf growth, stronger and larger stems and tighter internodal spacing. 

We gave Dr. Bugbee, professor at Utah State University our 385NM UVA Lightbar: 

"Your UVA lights arrived and we have confirmed their 385 nm peak. This looks like a high quality fixture." He went on to say: "Elevated exposure to UV photons is known to enhance the synthesis of UV blocking compounds in the leaves of many species and it is reasonable to think that UV photons can increase the synthesis of secondary metabolites in plants." And further, "I expect we will find value in dosing of CSativa plants with UV photons, but not surprisingly, the effects will likely interact with UV wavelength, intensity, timing of delivery, and growth stage."

The UVA Lightbar fits neatly inside the frame of our Uniformity Pro LEDs as well as many other multi-bar style full spectrum LEDs.
