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.

Not really good as a lip balm
It is way too melty or liquidy when applying. It's like putting oil on your lips. No staying power. I actually ended using it more as a skin moisturizer like a lotion. It's pretty good for that. I haven't even tried taking it with me in my pocket as I think it'll turn to a liquid like coconut oil down here in sunny hot Florida. .

What I needed!
Scent: Oatmeal & Honey
My skin it very sensitive and dry which makes finding a good soap difficult. I'm also not able to use exfoliating products as it is painful and/or damages my skin but a wash cloth isn't enough. This soap is great in that there are very few ingredients and they are all natural so no skin reactions. It is actually soothing. The whole oatmeal in it exfoliates but also softens so no pain or skin damage. Definitely plan to continue ordering this product.

A miracle for those with eczema.
Scent: Oatmeal & Honey
I recently bought the Goat's milk soap with oatmeal and honey. Let me just say that I LOVE this soap. For YEARS I have been trying all kinds of naturally derived soaps in search of a keeper, and I finally found it. A big thank you to The Soap Haven. I have been dealing with dishydrotic eczema on my hands and fingers for about five years now, and finding products that don't trigger outbreaks can be like playing with fire. I have found soaps that do just that, and I have find soaps that are mild enough not to do that, but I have never before used a soap that actually soothes my skin. This soap does that,it SOOTHES. Every time I use this soap, my eczema is almost healed and I am not exaggerating. I have had awful break outs, and after a few minutes of lathering with this soap, the itching goes away entirely, the redness subsides, swelling goes down and it has consistently been this way. Also, this soap leaves my skin feeling clean and comfortable - Not oily, not dry or tight, just really comfortable. Anyways, I am just so impressed and thankful, this soap is miraculous. Please don't discontinue or change this formula. You have a customer for life. Oh, and another plus, I live in Oregon, so I am proud to be giving my business to a business like this one. P.S. I read a lot of reviews that gave one star for the smell, or said it's not unscented, well it is fragrance free, the only thing that you can smell is the combination of honey, goatsmilk, and oats-and that is good! It is evidence that this is all natural soap with the ingredients it claims to have with no fragrance added for appeal. Now, in my opinion, this comes with the territory, if you want something that smells like a perfumery, then go with the synthetic stuff, but if you want all-natural, free of essential oils and parfum, then embrace the less popular smells of nature.

Nice moisturizing soap, expensive
Scent: Oatmeal & Honey
I have been using this soap for about a year. I like the skin calming and anti-itch properties of oatmeal, the soap doesn’t dry my skin, and there’s no scent, I also find it fairly long-lasting—once a sliver gets too small to use in the shower it goes into a soap dish by the bathroom sink and I wash my hands with it. Even a dime-sized piece will lather nicely. One star removed because I think this soap is more expensive than it needs to be.
