Why 385nm UVA?

How This Compares:

  • Standard UV lights: 395–405nm (visible violet)
  • FGI: true 385nm UVA
  • Standard: blended spectrum
  • FGI: single-band precision
  • Standard: IP65 or lower
  • FGI: IP68 fully sealed

Why UVA (385nm) Matters

Plant morphology is influenced by spectral composition. While PAR lighting drives growth, UVA wavelengths (around 380–400nm) play a role in plant signaling, structure, and secondary metabolite expression.

Unlike broad-spectrum fixtures, this unit allows growers to:

  • Introduce controlled UV exposure
  • Fine-tune lighting strategies
  • Experiment with spectrum-specific responses

Extended PAR (E-PAR) Context

Recent research, including work from Utah State University, has expanded the understanding of usable light for plants beyond traditional PAR (400–700nm).

  • E-PAR Range: ~380–740nm
  • UVA sits at the edge of biologically active light
  • Supplemental UVA helps bridge the gap between artificial lighting and natural sunlight

Natural sunlight includes measurable UVA energy (~380nm), which is typically missing from standard LED grow lights.

Applications

  • Commercial indoor cultivation (CEA)
  • Supplemental UV for flowering and morphology control
  • Coral fluorescence and reef systems
  • Mycology environments
  • Research and controlled trials

    Fully sealed aluminum housing with a bonded clear glass lens. Built for high humidity, washdown, and commercial grow environments.
  • Universal Input Voltage (100–277V)
    Ready for commercial installations without additional drivers or conversion.
  • 4-Foot Linear Coverage (44”)
    Even distribution across canopy rows, vertical racks, or coral systems.
  • 30W Precision Output
    Low power, high-impact supplemental lighting for targeted use cases.

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. 

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 a prominent researcher at a major State University one our 385NM UVA Lightbars: 

"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 CSat 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.

Use

We recommend two of our UV-A LEDs over each 4'x4' area. The slim design allows them to be hung inside the frame of most 6 and 8 bar LEDs. Mounting height should be at the same level to avoid creating shadowing. 

Control

A basic digital 110V wall timer can be used, or if using the TrolMaster Hydro X we recommend the DSP-1 module for 110V or DSP-2 for 120V power connection and multiple on/off timer programming.

Good choice to teach kids to be well-mannered at Memorial Day.
Format: Hardcover
The book starts with the 13 colonies each with their own flag. Then it discusses the Revolutionary war and the story of Betsy Ross with the qualifier that It says no one really knows who sewed the first flag. Then it discusses Francis Scott Key and the bombardment of Fort McHenry. Then how a star is added for each state added to the union. Mentions the Civil War and raising the flag on Iwo Jima. After that it has two pages on protocol for displaying and honoring the flag, and gives the pledge of allegiance. It is a good choice to teach kids to be well-mannered at parades and Memorial Day services. The cover art depicts a series of historical flags, not all of which are mentioned in the book which raises the question “Why?”. Starting at the back is the red Saint George’s Cross on a white field. Saint George the dragon slayer is the patron saint of England. The plain cross without the centered crown is the flag of England. This flag is shown on page 2 as the flag of one of the colonies but it doesn’t say which. In front of that is the flag of Maryland Colony which is still used as their state flag. Next in line is the coiled rattle snake Don’t Tread on Me flag. According to my Compton’s Encyclopedia, this originated with Esek Hopkins the first US Navy commander in chief and was used from 1776 to 1778. Colonel Christopher Gadsden presented a copy of this flag to the South Carolina legislature, so it is often referred to as the Gadsden flag but this is incorrect. The rattle snake image was used in 1775 by the minute men of Culpepper County Virginia. The image was widespread in the revolution and may have been used earlier than that. The snake is portrayed with 13 rattles, one for each colony. Rattle snakes will not initiate an attack on humans as we are too big to eat, but if stepped on they will counter attack and can be deadly. The point of the image is that the colonists did not want war, but would not tolerate abuse. (There is a rumor that this flag is connected to the slave trade, but Hopkins was from Rhode Island which was not part of the Confederacy, and I have not found any evidence to support this rumor). Next is the flag of New England which has the Saint George cross with a Pine Tree on a blue field. This flag was used at the battle of Bunker Hill. Normally the New England flag has a red field, but blue was substituted because the red caused confusion with the British Royal Navy ensign which has a Union Jack in the top left on a red field. Naval ensigns are designed to be highly visible at distance or in the smoke of battle. The bright red field is more visible than the Union Jack alone. The Union Jack is the national flag of the United Kingdom. Next is the Union Jack on a field of thirteen stripes. This is the first flag of the thirteen colonies. It was used in 1775 and 1776 as the flag of the continental army and navy but never officially adopted. Next is the Betsy Ross flag, followed by the Fort McHenry flag, and the modern flag. I hope this helps.

No progressive agenda! Perfect kids book!
Format: Hardcover
I'm a homeschooling parent of a kindergartener. As part of our social studies curriculum, I have been introducing the Pledge of Allegiance and the anthem, and I wanted to find a book that would go a little further into how the flag came to be and why we stand to say the Pledge, and this was the perfect book! It's written with great accuracy and at a child's level. There is also no progressive agenda, as I had discovered with some of the other kids books on the subject. It also lists when and how you are to stand for the flag, and has the Pledge printed in it. Would definitely recommend!
