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.

The softest skin you will ever have without any expensive products!!
Great for removing dead skin and peach fuzz. A lot of other blades have the little teeth that are great for preventing scrapes and cuts but don’t quite get close enough for me. You do have to be careful because they are very, very sharp and you can cut yourself. It does have rounded edge that is very helpful in preventing the little cuts. My skin is super smooth and my makeup goes on amazing after using. As a 47 year old that makes a huge difference.

Do not purchase
Size: #10R, Style: Pack of 10
Not sharp enough and does not work no matter what products you put under it to remove hair and how you use it. The durability is very cheap and it is not valuable even if it’s for less than $15. I would not recommend this product for your body including your face, upper lips, under arms, and anywhere on your body.

Individually wrapped blades for hygiene
Size: #14R, Style: Pack of 20
Very hygienic that it comes in individual packaging! Every blade comes with a cover and a small sandpaper to keep the blades sharp! Perfect to keep reusing on their own.

Great for Peach Fuzz, But Not as Sharp as I Expected
Size: #14R, Style: Pack of 20
I really liked that each dermaplaning blade is individually packaged, which helps keep them clean and sanitary until you’re ready to use them. As a hairstylist/barber who works with sharp tools every day, I did not feel like these blades were particularly sharp. That may actually be a positive for someone who is new to dermaplaning and wants something a little less aggressive. I used them on dry skin, but you can also use a facial oil for more glide. They did a nice job removing peach fuzz and left my skin feeling smooth afterward. Just be sure not to use them over active acne or irritated areas. While they worked well on facial hair, I didn’t notice much additional exfoliation from my first use. I’ll continue using them every couple of weeks and see how they perform over time. Overall, a decent option, especially for removing peach fuzz.
