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.

Great sudsy soap
I've been trying several all natural cleaning products and this is my favorite dish soap so far. Other all natural brands do not make near as many sides as this stuff. I compare the studs with this to what you get with Dawn, without all the harsh chemicals

Aroma Therapy During Dishwashing?
"So, once again, I was on the hunt for an effective and pleasant dishwashing product. The task became more challenging because it needed to not only clean well but also smell nice, and ideally, create a cozy atmosphere in the kitchen. In the end, I decided to try Mrs. Meyer’s Clean Day. According to the manufacturer’s claims, this product is completely safe not only for health but also for the environment, as it is biodegradable, along with the packaging components. The packaging itself doesn’t say much—it’s the usual 16 ounces, though it’s sold in a pack of three bottles. The product is marketed as suitable for people who prefer natural products because it doesn’t contain harsh chemicals. I can honestly say that the product met all my expectations. The first thing you notice when you open the bottle is the amazing scent that literally fills your kitchen with the freshness and fragrance of Verbena. Since we wash dishes with hot water, it’s not just a scent, but a real aromatherapy experience during dishwashing. As for its effectiveness, this dish soap works great, dealing with grease, food remnants, and even burnt pans. Additionally, it foams up well, so there’s no need to use a lot of it. Now I actually enjoy washing dishes! The only downside is that the product does run out fairly quickly, especially when you have a large family and a lot of dishes. Of course, this isn’t really a flaw of the product itself, but considering it isn’t very cheap, I would have liked it to last longer or for the price to be a bit lower. Anyway, I’m completely satisfied. Mrs. Meyer’s has become my reliable kitchen helper, without harming the environment."

THIS STUFF WORKS!!!!!!
First of all - RUN, DON’T Walk & get this. IT WORKS!!! I kid you NOT, that I can literally feel sprouts of hair growing out of the roots of my head! After washing my hair And drying it, I part my hair into several sections and gently massage it into my scalp. After at least a day or so, I can feel the tickle in my scalp, it feels like grass slowly growing. I have plenty of hair, but I would love to actually see this product used on someone who doesn’t have hair like me. I am using the product because of a thinning spot that I have from a sew-in that I have had multiple times, and getting it parted in the same area for over a period of time. You can Not beat this product, especially for the price.

Don't not purchase!!!!
Color: A
This is product has over ingredients, its made in China and the shelf life is 3 years! No naturall product has a shelf life of a 3 years or any storing instructions. Just an FYI when buying any product, the ingredient that's the most in the product is the first on this list of ingredients WATER is the first, Batana Oil is second to the last. the packaging say 100%, 100% what? Its truely not Batana Oil. I am sending this back ASAP and working on my own mix for my hair growth. I am dealing with scared alopecia and have been searching for things to help with my hair growth. I am tried of companies thinking they will take my money. I was not able to see the ingredients until I recieved the package, which is not a terriable way to sell a product.
