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.

Subtle but gorgeous
Color: Golden
I’d buy it just for the perfume bottle - just adorable. The glitter is light and gives a delightful shimmer on skin and hair. Not saying exactly how old I am but I remember the 80s…if you older and just want some sparkle THIS IS IT. It’s light cover and sheen is just enough to add some glam without looking like you’ve just come off the pole… If you are heading in that direction just use an extra couple of puffs of glitter and you go girl… Will likely buy more colors, so fun!

Love This Shimmer Spray!
Color: Silver
Absolutely love this glitter spray! I bought this for a party and it worked even better than I expected. The glitter is super fine and gives a beautiful, high-end shimmer without looking chunky or cheap. The spray nozzle is really easy to use and distributes the shimmer evenly on both hair and skin.

Shine bright!
Color: Golden
Shimmer is brilliant. It stays on longer if you add lotion to "seal" it in place. Small enough that it am not afraid it will hurt my eye if some gets in. Bonus that it has a refill. Bottle is super cute and glass.

Spunky Pup toys are the best for aggressive chewers! ❤️
Size: 1 Count (Pack of 1), Style: Heart
We have an Amstaff (American Staffordshire Terrier) who is definitely an aggressive chewer and a known toy destroyer. That's just how she enjoys her toys, lovingly tearing them to shreds and pulling their "guts" out. Sometimes she will allow the toy carcass to last a while so she can continue to play with whatever is left of it for a while longer. It has honestly been a challenge to find durable toys that she can't destroy, but Spunky Pup toys seem to be one of the only brands that can actually withstand our dogs tough love! Her first Spunky Pup toy we got her was a squeaky blue diamond gem, much like this heart gem, and it is still completely intact after several months of use! She loves it and we love the fact that it's so durable that she hasn't been able to destroy it. It squeaks and it bounces around sporadically, the unpredictability of not knowing which way its going to bounce adds a new level of excitement which seems to keep her attention a little longer. She loves her diamond and she was super excited to get her new heart gem! They're pretty similar, so she loves them both, although the heart one seems to be just a little smaller and therefore a little easier to catch in her mouth. But it doesn't stop her from trying (and most of the time succeeding) to catch the diamond one in her mouth, it's just not as easy to catch as a normal ball. Spunky Pup toys are really durable and super adorable! We are definitely going to be buying more Spunky Pup toys to add to her growing collection. 100% recommend for aggressive chewers!
