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.

Super Soft, Cozy Throw
Size: 50"x70", Color: Berry Cheetah Pink
I got this blanket and the first thing I noticed was how incredibly soft it is, it has that smooth, plush feel that makes it really comfortable to use daily. The size is great for lounging on the couch or adding an extra layer on the bed without feeling bulky, and it gives good coverage for a throw blanket. Many versions of this style are around 50 x 70 inches, and medium weight which is ideal for everyday use. It’s also easy to care for, I’ve washed it and it holds up well without losing softness or shape. The quality feels nice for the price and it still looks good after use. Overall, it’s one of those blankets you keep reaching for because it’s soft, practical, and low maintenance.

Super Soft and Adorably Stylish
Size: 50"x70", Color: Cherry Cakes Hot Pink
I recently got the Juicy Couture Kids Cherry Cakes Plush Throw Blanket, and it has quickly become a favorite. The blanket is incredibly soft, lightweight, and cozy, making it perfect for relaxing on the couch, adding extra warmth to a bed, or taking along for travel. The hot pink color and cute Cherry Cakes design are vibrant and fun, especially for kids who love colorful décor. Despite being lightweight, it provides plenty of warmth and comfort without feeling heavy. It also washes well and maintains its softness, which is always a plus. For the quality, comfort, and adorable design, this blanket is Highly Recommended.

Cute, soft, and large blanket!
Size: 50"x70", Color: Cherry Cakes Hot Pink, Size: 50"x70", Color: Cherry Cakes Hot Pink
Very cute and warm throw blanket! The blanket is super soft and has great weight to it. Sometimes these throw blankets with prints look weird on the “back” side but, this one’s print goes all the way through. Or sometimes it doesn’t feel as soft on the back side. But this blanket isn’t like that. This is a high quality blanket! I also love the size of the blanket! It’s much larger than the standard throw so it’s perfect for someone who likes to get cozy on the couch!

Get this blanket!
Size: 50"x70", Color: Berry Cheetah Pink, Size: 50"x70", Color: Berry Cheetah Pink
This juicy blanket is such a nice quality! The softness is absolutely incredible the weight of the blanket isn’t light but isn’t super heavy. The pink is gorgeous my phone camera had a hard time actually getting the pink colors I think my second photo is the most it picked up but the entire blanket is pink I love the bows and the cherry’s and how it of course has the signature juicy on some of the cherrys. The material is super soft. I mean incredibly soft! It’s perfect. I know it says for kids but I’m an adult and I love it I’m 4’10 so it’s long enough to cover my whole body and keep me warm at night I also move to cuddle with it on my face or bring it to the couch to stay warm. I really love love love this juicy blanket and I highly recommend it it’s a great value for the quality you get.
