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.

My dogs love these toys!!
Pattern Name: 8PCS No Stuffing Dog Toys
My dogs love playng fetch with this toys! They love to hear the crinkle sound of the paper, as well as the little squicker insider... They stand up to my rat terrior who is a very aggressiive chewer who plays with theses toys for hours on end!

Not for tough chewers

Cute, but they didn't last very long. Puppy tore them apart very quickly but she had a lot of fun doing it.

FUR BABY APPROVED!!
Pattern Name: 8PCS No Stuffing Dog Toys, Pattern Name: 8PCS No Stuffing Dog Toys
I have 2 spoiled little diva fur babies that are very picky when it comes to their toys. I have an 8lb, 10 year old Schweenie (Shih Izu/Dachshund mix) and a 1.5 lb, 11 week old Yorkie and they both LOVE LOVE LOVE no stuffing/crinkle toys. Unfortunately, we don't have many because they're hard to find and usually overpriced. This set here is worth EVERY PENNY!!! I was genuinely so shocked when these arrived. This whole set is by far the best I’ve seen or bought. Each of the toys in this set have been created with a very high quality textured fabric. Each is a different design, color and texture. As an experienced seamstress, I can confirm that each of these toys have been carefully stitched to withstand lots of play time, chewing and games of tug of war that involves sharp little teeth. This set of toys range in size from about 5” to 10”. I highly recommend this set.

Perfect for my 2 pups!!
Pattern Name: No Stuffing Dog Toys
I have 2 black Labs, one is 2 years old and the other 4 months. They LOVE to play tug o war and wrestle with toys, but my puppy with her smaller mouth and baby teeth has a hard time holding the stronger silicone chew toys (we love the brand west paw) my older dog likes. Ropes shred and are annoying. They love plush/soft toys, but once the stuffing comes out they start eating it so it’s game over. I still would get them cheap dollar store stuffies just for 10 mins of supervised fun, then they’d go in the trash. THESE however bc they have no stuffing or filling whatsoever, my dogs can just tug and tug until the fabric literally falls apart which is perfect!! With each toy we’ve gotten well over an hour of playtime, which is amazing. And they tug HARD... so while they may rip an arm off the octopus or a claw off the crab, the body stayed intact so they could keep playing. I was very impressed with the durability of the fabric. These satisfied our need for a fun, cheap toy that we were okay with getting destroyed eventually. Will these last forever? For a big dog/tough chewer no, but they’re cheap and provide some serious fun. Yes they’re flat - they have no filling. But they are soft and adorable!! And approved by my two girls! I highly recommend and will buy again!!

Not for large dogs or chewers
Pattern Name: 8PCS No Stuffing Dog Toys
These are not for large dogs. They are cheaply made. They get dogs attention because of squeaker and crinkle but are easily torn apart (cheap fabric and felt). They might last with small dogs or puppies. Definitely not for actual chewers. Didn’t even last 15 minutes.
