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

  • 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.

An indispensible Hebrew Language resource.
Format: Hardcover
This book is an amazing resource for anyone who has completed preliminary Hebrew such as with Pratico and Van Pelt in their Basics of Biblical Hebrew. This book goes above and beyond, it gives the diagnostic origin patterns for adjectives, patterns in noun formation as well as other components of speech, contrasts each of the seven major verb forms and the minor forms as well, and gives an excellent evolution of the utilization of the Hebrew language and its update in characters. It explains in its initial history a lot of unique statements in the Torah, and illustrations throughout give the reader an excellent idea about the Hebrew Scriptures. I bought this to aid in designing a language studies course at seminary and it has stood me in great help so far, going beyond anything I would have expected to get out of an intermediate level grammar and is an amazing, invaluable, and priceless resource, both to the professor, and the student. I recommend all people taking Hebrew purchase this book and add it to their collection and read it through cover to cover as well as using it as a topical reference guide.

can potentially be overwhelming
Format: Hardcover
This is a good resource for introduction to syntax. However, the vast amount of examples has benefits as well as disadvantages. The benefit is that it is comprehensive in information which makes it good for a reference. The disadvantage is that the many subcategories can cause one to be discouraged as the quantity of information may be overwhelming. Nonetheless that is the nature of learning a language. It is still a good resource if you can maintain the brain power to understand the technical language if you have a novice background to linguistics. The volume could be more pedagogical however that would cater to the self learner and perhaps that was not the intent of the author. This volume seems to be designed for the classroom setting. However it is still decent for the self learner.

Favorite Hebrew Reference Book
Format: Hardcover
This is the Hebrew grammar that I use the most often. While I also use Williams and Arnold and Choi, this grammar is more comprehensive, and its size certainly reflects this. It probably betrays my inclination towards the exactness of Greek to like this grammar so much. As my Hebrew professor often tells us, all these grammar categories are contrived to some extent, so at some point it isn't helpful anymore to go further in depth on the uses of the so-called "cases." All in all, I usually find it easy to locate the grammatical point in which I am interested, though sometimes I have to resort to looking up every instance a Hebrew particle occurs throughout the book. For this looking up of various nuances of a particle, I sometimes find Williams more user friendly. Nevertheless, Waltke and O'Connor's volume has been my resource of choice.

Format: Hardcover
If you are a serious student of Hebrew this is the only way to go. The book explains how the language is built from the ground up. If you are like me you have found learning Hebrew challenging (that's a joke). I have tried learning vocabulary, rote memorization, even coming up with silly English sentences to help me remember words (The goddess "Hera" is quick) (sad, I know). This tool is essential approaching the language from the building block side of things and I am now able to look at the prayer book and recognize forms and tenses I never understood before. It is for the serious student who REALLY wants to learn the language.

Can't do Without
Format: Hardcover
I have been a fan of Gesenius for a long time. While I knew there was updated information to consider, I thought his text was enough. But although his text is certainly still necessary, and necessarily covers issues that the book reviewed here does not, it is clear that one must turn to Waltke & O'Connor to reach a greater level of accuracy. Writing so long after Gesenius, they have presented new and accurate information based on the latest research, not only of Ancient Hebrew, but also based on cognate Semitic languages. I have found the sections on Hebrew verbs the most enlightening and correcting, e.g., that the Pi'el stem is NOT intensive. Such intenseness must be detected from a combination of the lexical verb meaning, the stem, and the text/co-text. This book also presents other up-to-date information on the forming of nouns from verbs, etc. As others have noted, the layout and presentation is great. It really can't be presented any easier, I don't think. One must read Gesenius, for he presents very important information across the board, including much on phonology and linguistics not covered by Waltke & O'Connor. But to stick with Gesenius will leave one in error on some points. Waltke & O'Connor, simply put, make the corrections and make studying Biblical Hebrew exciting, and even much easier to learn.
