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.

Perfect Teething Toy for Puppies!
Color: Pacifier, Size: Small
My puppy absolutely loves this Nylabone Puppy Pacifier Chew Toy! The bacon flavor immediately caught his attention, and it has quickly become his favorite toy. It’s the perfect size for small puppies and easy for little mouths to carry around and chew on. The material is soft enough for teething but still durable enough to hold up to daily chewing. It has really helped redirect my puppy from chewing on furniture and shoes, and it seems to soothe his gums while he’s teething. I also like that it keeps him entertained for long periods of time. Great quality, puppy-approved, and definitely worth buying for any small dog owner!

My dogs love these
Color: Pacifier, Size: Small, Color: Pacifier, Size: Small
These are my dogs favorite toys and they keep them entertained for hours. Yes they are able to chew them down to small pieces but they are sturdy enough where they won't swallow them. I have miniature dachshunds so small dogs.

Perfect for Teething Puppies and Adult Dogs and Keeps Them Busy
Color: Pacifier, Size: Small, Color: Pacifier, Size: Small
The Nylabone Puppy Pacifier Chew Toy has been a lifesaver during my puppy’s teething stage and AFTER. Quality: The material is sturdy yet gentle enough for developing puppy teeth. After weeks of daily use, it shows normal wear. The pacifier shape makes it easy for small mouths to grip and carry around. Effectiveness: It’s great for soothing sore gums and redirecting chewing behavior. I’ve noticed my puppy is calmer after chewing on it for a while. Helpfulness Tip: Supervise during chewing sessions and wash it occasionally with warm soapy water to keep it clean. If you have a small-breed puppy under 25 lbs, this toy is a safe, durable, and fun way to help with teething. Bought twice, they love these. Miniature dachshund and French bulldog
