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

Core Features

  • True 385nm UVA Output (Single Spectrum)
    Narrow-band ultraviolet designed for controlled application. No blended or diluted spectrum.
  • IP68 Waterproof Construction
    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.

Why are these books so hard to find in libraries and bookstores??!
Format: Paperback
Bought nearly the whole book series after reading the reviews. My 8 and 10 year old boys love these books. My 10 year old read the first book on his way to and from soccer practice. He couldn't put it down and kept telling me what he read. My boys have read all the "Magic Treehouse", "I Survived" and some "I Escaped" books, as well as "Big Nate", "Diary of a Wimpy Kid", etc. BUT these battle books are the best. They really teach about the history of the wars which have shaped our modern times. WHY are these books so hard to find in libraries and bookstores... at least in Maryland? Maybe because "Great Battles for Boys" reeks of toxic masculinity? I really wonder. In any case, great books especially if you want your boys to read serious, informative books that are interesting and entertaining.

Great for boys AND MOMS
Format: Paperback
Saw an ad for the series online and wanted to buy just one book to try. Received with 2 day Prime. Book was new. So, not only does this book have an incredible, intriguing story that sucked in my 10 year old who hates reading and struggles to read, it had me at Hello. The beginning of the book is filled with recipes! Was totally not expecting that! So for this Momma, under promise-over deliver was the theme here. Purchasing the rest of the books! Also look online for worksheets that parents have put together to go along with these books. Totally worth it. Happy Reading! AND Cooking!

Great reads for all levels
Format: Paperback
I bought 2 for a 6th grade boy I tutor. He has a beginning interest in history. He's been 'eating' these books up! These are well written, but not complex to turn a young reader off. There are many alternative resources to listed to dive into if a particular person or event sparks interest with the reader. There is appropriate vocabulary with explanations on some- others open a chance for my student & I to have a deeper discussion to clarify meaning & connect information.

Great book for an (almost) 11 year old to learn about WW2
Format: Paperback
My (almost) 11 year old says he enjoyed this book because it gives specific details and has pictures of what was going on making it easy to understand what was happening. The only thing he’d change was that the pictures weren’t in color (lol)!
