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.

Luxurious Feel, Durable Build… but Full Rotation Privileges Have Been Revoked 💙🦴 🐾
Color: Blue, Size: 6 IN, Color: Blue, Size: 6 IN
🐾 Hi, I’m PVD; toy curator, plush critic & occasional chew sommelier. This armadillo arrived beautifully packaged and immediately met my standards for texture, squeak clarity and cuddle factor. I originally gave it 5 stars for quality; and still do! But today I’m updating the review to reflect my current toy lifestyle rotation. 😌 What impressed me from day one: ✔️ High-end plush feel; soft enough to nap on, tough enough for energetic zoom bites and great relief from teething ✔️ Strong stitching; survived multiple “stress tests” (I chewed with intention) ✔️ HQ squeaker; not tinny or annoying, more of a honk ✔️ 6in is perfect size for small breeds; easy to carry during dramatic hallway walks Why it now gets 4 stars from a seasoned toy collector: ✘ As my luxury toy collection expanded, this one gets grabbed less often ✘ Simple design; I now favor more interactive or complex textures ✘ Still “keep-worthy,” just no longer VIP spot on the chaise lounge Best For: • Pups who enjoy soft comfort toys or emotional support snuggles • Light to moderate chewers • Dogs who like to carry their plushes around proudly • Ideal as a teething toy or thoughtful gift 🚫 Not ideal for: power chewers or highly stimulation-driven pups (like me now; my taste evolved) 📝 Final Re-Barks: Still recommend for pups who love cuddly squeaky companions. Great starter plush and great quality; just know that ultra-picky toy enthusiasts may rotate it out once newer models (or squeakier friends) arrive. — PVD (Plush Aficionado, Toy Rotation Director & High-Maintenance Household Icon) 🐶💁🏻‍♂️✨

Well Constructed Toy But Short-Life Squeaker
Color: Gray, Size: 8 IN
Super cute and durable toy. Makes a "grunting" noise that my dog loves. However rating a little lower because my dog has only been playing with it (gently) for a couple weeks and the grunting noise is starting to die. But she does really like this toy regardless!

Cute and soft dog toy!
Color: Gray, Size: 8 IN
This very cute armadillo dog toy is nice and soft for our Golden Retriever to carry around in his mouth. He eventually likes to pull off the legs, ears, or anything else extending from the body of the toy and so far he hasn’t been able to do so with this one. Not saying that it’s not possible, so as with any toy, you should monitor your dog playing with it as we definitely have to. He also likes to continually make his toys squeak and this toy’s squeaker works very well!

Great Toy for tiny to giant pups
Color: Gray, Size: 8 IN
Cute Amarillo. My teacup Yorkie uses it as a pillow or chases and attacks it. Well stretched does not easily fall apart. Good value for the money. Suitable for all sized dogs.

Fun dog toy, but not for heavy chewers
Color: Pink, Size: 14 IN
The armadillo is cute. My pittie, Sasha, was very excited to see it. She just had TPLO surgery on her left knee (she tore her ACL just before the 4th of July), and I wanted to get her something she could play with while she convalesces, that isn't a ball—she really likes to run and jump and chase the ball, but with her knee out of commission, I didn't want her to get depressed being trapped in her crate while she heals—with this toy, she was able to keep playing and not over excert herself and get more hurt. It quickly became her favorite toy; she chews it relentlessly and gets made when I take it from her (see below). It makes a funky squeak that's not a high-pitched squeak, like I thought it would be; it's more a low-pitched, lowing sound like a baby calf. One thing I would like to point out to other purchasers about what the description says: "Durable and Long Lasting - Made from premium soft materials, our cute plush dog toys can withstand rough play for indoor or outdoor and last for years to come. The textured surface also helps massage and soothe your dog's gums during playtime" This is a little misleading. It's a good texture and Sasha loved to play with it, but it wasn't very durable. It might be when compared to other chew toys, but not for my baby. She tore the nose off within 20 minutes of getting it. The next morning, she ripped off an ear, and I had to pull the stuffing out of the face so she wouldn't eat it while chewing away. She doesn't seem to mind, but I sure wish it had held up a little more. All-in-all, this was a good toy for a few days.
