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.

Bristles are soft and dense but a little too long for cats but still the best so far.
Very good brushes with dense but soft bristles. The pros are the excellent bristles as they are abrasive enough to actually clean my kitty's teeth. I have to work really fast to clean her teeth. These bristles make the cleaning a bit more efficient compared to the silicone bristles that I have used prior to this. The cons of these brushes is that the length of the bristles are too long. These are better suited for dogs, but for cats, their mouth is a lot smaller. There isn't a lot of space to insert this brush between the inside of my kitty's cheeks and the side teeth. I wish the bristles were shorter. There is no way for me to trim them shorter because then the bristles will no longer be soft. Having said that, these pair of brushes are still the bets so far that I have used. The bristles really makes all the difference.

Works well with cats.
The bristles are nice and soft, so it makes it easier to brush my cat's teeth. It did take a little while for my kitty to get use to the brush, but the more I brushed my cat's teeth, the more he got use to it. This is a great set of toothbrushes that will help keep your pet's teeth and gums healthy.

Really soft bristles, good for small dogs
My dogs are not the most cooperative when it comes to brushing their teeth. These toothbrushes are very soft which is nice. My dogs licked the toothpaste off and declined to let me brush their teeth but this is not a reflection of the product. Because the toothbrushes are small, these are best for small dogs. They come with clear storage cases which is nice. Just let the tootbrush air dry and store. The top has a pull lid to help remove it.

Soft bristles & comfortable grip
Great pet toothbrushes! So glad I ordered these. The bristles are super fine and gentle on the gums. They are dense so they actually can brush the teeth and gums without pressure or scratching. The 2 toothbrushes (one pink and one blue) come with handy storage cases. The third brush is yellow for between teeth cleaning. Also supersoft. I especially like that the toothbrushes are on a narrow base that fits easily in my small dogs’ (5lbs & 18lbs) mouths. The handle is also comfortable to grip for easy control and safety.
