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 pants, big pockets, order the right size
Size: 14, Color: Tan
I love these. Amazon thought I was a size 14 but I have to return those. I got a size 12 and love them. Very comfortable, and high waist. The pockets are huge which makes it seem a little weird if you don’t get a small enough size. I have wide hips and a big bottom, and instead of a size 14, a size 12 fits but will probably buy again and get a size 10 in the future. Great for work.

BEST EVER - But you may need to go up a size
Size: 14, Color: Blue Format
Absolutely the BEST jeans ever, particularly for over-50 women who like high-waisted jeans that don't look like "mom jeans." I cannot praise them highly enough. I've purchased four pairs!! The price is outstanding, the quality is superb, and they have ACTUAL pockets. (Why do manufacturers think women don't need real pockets?) I needed to order a size larger than the size guide indicated. The first size I ordered was both tight and too short. The next size up fit like they were made for me. The waistband has a stretchy, comfortable band sewn in that keeps it in place. No high-rise becoming mid-rise because they ride down. (For some of us, our waist is NOT the narrowest part of our torso so the waistband needs to be specifically designed to stay put.) The dark blue color will bleed, so wash by themselves the first time. These jeans look amazing - like those that cost WAY more! I promise you will NOT be disappointed. I wonder if I need a fifth pair...

Love these!
Size: 16, Color: Deepest Dark
I recently bought the Lee Women’s Ultra Lux Comfort with Flex Motion Skinny Leg Jean with Ever Fit, and I’m honestly so impressed. The first thing I noticed was how soft and stretchy the fabric feels without seeming thin or cheap. These jeans move with you all day, whether you’re running errands, sitting at work, or going out for dinner. The Flex Motion waistband is incredibly comfortable and doesn’t dig in at all, which is a huge plus for long wear. The fit is flattering and true to size. They hug in all the right places while still being easy to move around in. I especially love that the Ever Fit design helps them keep their shape throughout the day, so they don’t sag or get baggy at the knees like some other skinny jeans I’ve tried. The quality feels excellent for the price, and they look polished enough to dress up with boots or keep casual with sneakers. After washing, they held their color and shape beautifully. Overall, these have quickly become my go-to jeans. Comfortable, flattering, and durable, they’re everything I was hoping for. I would absolutely recommend them to anyone looking for stylish everyday skinny jeans that truly last and feel amazing daily.
