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.

Great case — perfect fit and solid protection
Color: A-Navy Blue
I’m really happy with this case. It fits my iPad perfectly, feels sturdy, and the clear back still shows off the design. The built-in screen protector and Apple Pencil holder are super convenient, and the stand works well for watching videos or typing. Overall, great quality for the price — highly recommend!

Get one!
Color: Peacock Blue, Color: Peacock Blue
Very nice IPad case. It fits really nicely. It took a while to get it setup because of how well it fits but it is well worth it. I love the he fact it uses magnets to position the screen instead of tracks. Stays in place while working instead of slipping throughout the day. I would and will recommend and buy again.

decent case
Color: A-Navy Blue, Color: A-Navy Blue
Its pretty good for its price. it definitely fits and is easy to install. the material is a very nice feel. my only issue is that trying to get to the power button/fingerprint may be a little annoying, Im not sure if its only me though.

Works Perfectly for 2025 Apple iPad A16
Color: A-Navy Blue
I was super surprised that the entire case had protective plastic to keep it scratch free before use. I bought it under $20 which is a really reasonable price. I wanted a hard case that could be angled in any which way I needed. I wanted it to be able to be used on a desk, table, my lap, and even in bed. The one major thing that I looked for was it's front cover display to use be used as a stand. A lot of cases use the inside of the cover to be placed face down on surfaces, which in turn, collects debris and other unwanted nastiness. Rarely can you find something as simple as that on Amazon, ironically. I tried it on the table and the magnets are incredibly strong. I lifted up the entire iPad and the front cover stand stuck together. It takes a good amount of force to adjust. That was a massive surprise and major benefit of getting this case that wasn't advertised. I don't care too much for the Apple Pencil holder on the top and feel it's an unnecessary feature. I use my iPad as either an extended display for workflow or just to watch movies, play games, and surf the internet. One of the things I did was remove the screen protector which was super easy to do. I don't need it since I already have a screen protector installed. Installation was super easy and removing the protective plastic was satisfying. The rubber is malleable enough to where it feels sturdy, but it allows installation to be simple and easy. The frame is nice and thick, alongside the protective cover. I have full confidence that if I dropped my iPad, it will survive without issue. I'm not concerned about the color, but it looks as advertised in the photos. I bought the blue one because it was the cheapest one and it ironically matched my blue iPad. Overall, and excellent purchase for an excellent product!
