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.

Soft and luxurious, high quality - but don't buy if you have cats
Color: Ivory White, Size: 2' x 6' (Sheepskin Shape)
I give the rug a five-star rating because it deserves it. I was really surprised at how good the rug is right out of the package (it was packaged very well too). Because this rug is relatively less expensive than many other listings of natural sheepskin rugs on Amazon and elsewhere, I wasn't expecting much. But it turned out to be thick, soft, fluffy, plush, and luxurious all over. Many years ago I have purchased another natural sheepskin rug from Amazon described to be of the same size as this one (I got the 2'*6' one), but this one is definitely much bigger in its actual size. It's hands-down a high-quality, high-value purchase if you want a nice natural sheepskin rug. I also love how beautiful the natural creamy white color is. Now, the story takes a turn. It does have a "natural and organic" smell as mentioned in many other reviews. The smell itself is not repulsive. I don't know how long it will take for it to air out (my last rug never really got rid of the smell, but it was not a big issue since I put it on the floor. I lost the rug in cross country moving.) But now I have a cat! My cat just couldn't resist tackling the rug the moment it was laid on the floor. She probably imagined herself to be a lion or a tiger who just caught some big prey. She couldn't stop kicking and biting the rug, trying to tear it apart. She came back to it a few times after breaks already. And this is day one. I am guessing this smell does stimulate some instinctive call from her genes. In a few short moments, she managed to tear off quite some fur from the edge of the rug... The rug still looks fine since I just received it today. I am not sure how long it will last with my cat though. Before ordering, I thought about this possibility and googled whether cats and sheepskin rugs can co-exist. I got many cute picture results showing angelic cats resting contently in the long and soft sheepskin fur, looking totally adorable and peaceful. Many articles say that natural rugs calm our fluffy friends down. Well, I told myself "perfect!" Win-win for me and my cat. Now, here we are, the beginning of my cat's conquest of an imaginary lamb (which was a real lamb.) I cannot even return it since it has already been damaged by my cat... In the worst case, this rug would become a really expensive cat entertainment piece that would eventually be destroyed....:((( I even started feeling guilty for buying animal-based products - but then comforted myself by remembering reading somewhere that cow and lamb leather goods come from animals that would be slaughtered for meat consumption anyways. My cat is already eating canned food containing Australian lamb, etc, etc. Really need to stop the thoughts. So this is my review. Beautiful rug of excellent quality and unbeatable value, unless you have a cat(s).

Perfect for a queen bed
Color: Tan, Size: 2' x 6' (Sheepskin Shape), Color: Tan, Size: 2' x 6' (Sheepskin Shape)
I LOVE this rug. I’m so glad I bought this instead of a cheap dupe. Reasonably priced, arrived quickly, doesn’t smell. It’s super soft and fluffy and really dense, so far I haven’t noticed any shedding. The size is perfect for draping across a queen bed. The color is beautiful and feels very natural. I might buy a second one for my bus conversion! Thank you so much!
