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.

Amazing product - instant smoothness
Size: 1 Fl Oz (Pack of 1)
I've only had this product for the last several days, but, so far, it's AMAZING. I've tried hyaluronic products before, because everyone says that you are supposed to for moisture, but, honestly, I was always underwhelmed. They were thin and did nothing. So, despite this one having great reviews, I was not really expecting anything, but the price was right. But this product....although liquid and clear, it's got a slight thickness to it, and spreads on very smooth. You only need a little bit to cover your entire face. Despite the slight thickness, it's not gooey or sticky at all, and it dries incredibly fast. In fact, if you don't spread it around onto your face quickly enough, it's already drying. There is no real smell to it. And, as soon as it dries onto your face, your skin feels incredibly smooth. Maybe it wouldn't if you had a significant dry skin problem to begin with, but for regular, maturing skin, it leaves skin baby smooth. And it lasts all day, and my skin looks better. I have very sensitive skin, and most things on my face eventually make my eyes water (even gentle facial moisturizers and sunscreens), but, so far, I haven't had an issue, and, because it's been a few days already, maybe I won't. Doesn't really feel like I'm wearing anything, and isn't a problem if I want to layer it with something else. I do wash it off at night, and can tell that something is still on my face even at the end of the day because it's a little slippery when I wash it. So it has staying power. For the price, I would definitely consider trying this product for moisturizing, and instantly smoother and softer skin.

plumping hydration with no greasiness or oiliness
Size: 1 Fl Oz (Pack of 1)
Its featherweight and melds with the skin in an instant. It plumps without any residue or "slip" on the skin. I have normal skin that tends toward slight dehydration and I use adapalene and the Ordinary 2% Salicylic acid anhydrous for my sebaceous hyperplasia. Because of the sebaceous hyperplasia and the heat and extreme humidity where I live, I cannot use anything with oils or dimethicone or anything even remotely occlusive. This serum is a great way for me to get appropriate hydration without exacerbating those enlarged oil glands or making my face sticky and oily. I dont need my face sealed, a humectant like this pulls plenty of hydration into my skin and I dont lose it to the air because of the ambient humidity. Its pretty perfect for me. It also has kept my barrier intact while alternating the adapalene and salicylic acid. Its a huge bang for the buck, I mean the price point is unbeatable.

It's great for food delivery and driver jobs
Size: 7''x3''
My husband got this for food deliveries and uber/Lyft. The app let him add several texts. I believe he added 4. He was able to design it how he wanted it. It seemed fairly easy and I liked how it looked. The words would scroll over, like... Uber eats, etc... It included a big roll of strong red tape. The led screen product is charged by wall plug, phone, or the car usb phone charger. I think it was a spectacular product. I thought it was limited to 4 letters since it is small in size.
