Commercial 385nm UVA LED light bar for supplemental UV in grow rooms, coral systems, and controlled environments.

Quick Specs:

  • Type: UVA LED Light Bar
  • Wavelength: 385nm (single-band)
  • Length: 44 in (4 ft)
  • Power: 30W
  • Voltage: 100–277V AC
  • Waterproof: IP68
  • Housing: Sealed aluminum + glass lens
  • Applications: CEA, coral, mycology
  • Bundle: 2 units

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

 Most grow lights stop at 400nm. Natural sunlight does not.

  • UVA range (380–400nm) exists in sunlight but is typically absent in LED systems
  • This wavelength range influences plant morphology and secondary responses
  • Allows growers to fine-tune spectrum beyond traditional PAR lighting

This is not a broad-spectrum “blue boost.”
This is precision UVA supplementation.

Science + E-PAR Context

Research from Utah State University and others has expanded the usable light range for plants:

  • E-PAR: 380–740nm
  • Extends beyond traditional PAR (400–700nm)
  • Includes UVA at the edge of biologically active light

Adding 385nm helps create a closer spectral match to natural sunlight conditions—something standard LED fixtures lack.

Bundle Advantage (2 Units)

  • Wider canopy or rack coverage
  • More uniform UVA distribution
  • Flexible placement across grow zones or systems

Commercial Build Quality

  • IP68 Waterproof – fully sealed for wet, humid, washdown environments
  • Sealed Aluminum Housing + Glass Lens – durable, corrosion-resistant
  • 100–277V Input – plug into commercial power without modification
  • 4’ Linear Format (44”) – ideal for rows, vertical racks, or coral systems

Applications

  • Indoor commercial cultivation (CEA)
  • Supplemental UV strategies for flowering or morphology
  • Coral fluorescence and reef systems
  • Mycology and controlled environments
  • Research and spectral testing


Sunlight Levels of 380NM UV

Natural sunlight provides plants 1.22 umols of 380nm blue energy. 

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 one of our UV-A LEDs and he said: 

"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 CSativa 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.

Made my bathroom look beautiful
Color: White, Size: 15.7 Inches
The mounting and the color were excellent. I hung this in my bathroom and thought it was going to be a hard install for me. The hardware that came with this was very self explanatory. The fit was perfect and the quality was great. I would surely buy this item again in the future

Great wall shelves!
Color: White, Size: 15.7 Inches
Great quality, and firmness. easy to set up. will need a drill to speed up process. White wood finish is really nice, not glossy so perfect for me. width is a little on the shorter side depending on what youre looking to place on them but true to sizing as described

Floating Shelves
Color: White, Size: 15.7 Inches, Color: White, Size: 15.7 Inches
I purchased a set of white floating shelves for my bedroom a couple months back, and I must say, they have definitely added a touch of modern elegance to the space. The installation process was surprisingly simple and straightforward, making it a breeze to set up the shelves exactly where I wanted them. The package came with all the necessary hardware, including sturdy brackets and screws, ensuring a hassle-free setup experience. I will say that the wall anchors included are not the best quality and I used a third party set. The sleek and minimalistic design of these floating shelves instantly caught my eye, and I couldn't be happier with how they complement the overall decor of my room. The clean lines and the bright white finish pop with the walls, providing a chic and uncluttered display area for my decorative items, and cherished keepsakes. They truly elevate the aesthetic appeal of any room and create an illusion of more space, which is always a bonus. However, one aspect that did disappoint me slightly was the visibility of the screws underneath the shelves. While the overall appearance is sleek and sophisticated, this minor flaw hinders the shelves from achieving a truly seamless "floating" effect. I understand that the screws are essential for stability and security, but I wish the manufacturer had found a way to conceal them better, perhaps with a cleverly designed cover or by providing white screw caps. Despite this minor setback, I still appreciate the functionality and attractiveness of these floating shelves. They have undoubtedly decluttered my living space and allowed me to proudly showcase my favorite items. I have received compliments from friends and family on how the shelves enhance the ambiance of the room. In conclusion, if you are seeking easy-to-install, stylish white floating shelves to add a contemporary touch to your home, these shelves are an excellent choice. Their seamless installation and sleek appearance make them a delightful addition to any room. Although the visible screws detract slightly from the overall aesthetic, the shelves' overall performance and elegance more than make up for it.

Good Product
Color: White, Size: 15.7 Inches
Well designed and sturdy. Though not real wood I think they will last. It took me an hour to install the first shelf. That was all on me. I was slow measuring and placing the shelf bracket. I kept dropping the level and doing other crazy things. But the second and third shelves were easy after I learned what I was doing. Even though the screws, etc were provided I used Easy Anchor drywall anchors rated at 50 pounds. Just drill it in the sheet rock then screw the screw through the hole in the bracket until it clicks, (you have to listen). That means the ends of the plastic anchor flips out like a toggle bolt. Continue tightening the screw and that is it. Think I read somewhere that the board wobbles. These were tight as could be and no wobble. I did learn to only "tighten" just one end of the bracket sort of snug and let it hang. Then raise it to level and mark the other holes with a pencil. Don't put the other screws in until you are sure you can see the plastic anchors' holes though the bracket. Then place and tighten all the screws. The only negative I saw was that they could have sent the same or similar anchors that I have. But they didn't call me. Guess they didn't have my number.
