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.

Don't buy AppleCare from Amazon, won't "attach" to your device automatically
Style Name: MacBook Pro 14" (M4), Configuration: 3 years
As another reviewer said, Amazon should not be allowed to sell digital items like these and fail to deliver them. That's called a scam. I have yet to receive my AppleCare agreement, but Amazon was more than glad to charge my Amex right away. Purchasing AppleCare from Amazon will only get you to a download of a PDF of the general terms and conditions, from your "Software Library", but it is not YOUR actual user agreement, and will not register on your device. Amazon will not help either, they will refer you to Apple support, and Apple will tell you that without an Agreement Number, they can't apply your AppleCare to your device. Since the PDF Amazon directs you to is a simple General Terms and Conditions document, there is no Agreement Number. In addition, the purchase invoice doesn't show this Agreement Number nor the device's Serial Number (which Amazon claims is recorded with the purchase... it's not) Save yourself the headache, and buy AppleCare direct from Apple, it will be about $60 more, but the "savings" is not worth dealing with this Amazon stuff. Amazon will also refuse to process a refund, stating that "only Apple can do that". Guess Amazon is telling you to contact your credit card and initiate a chargeback for services not received as paid.

Was skeptical but it worked out of the box
Style Name: MacBook Air 13" (M4), Configuration: 3 years, Style Name: MacBook Air 13" (M4), Configuration: 3 years
Was skeptical at first but decided to pull the plug and get the m4 laptop with 3 years of apple care and it works. Haven't even opened an email or anything, laptop was still fresh out of the box. When I remembered I bought apple care and decided to check. Applied instantly as far as I know once I linked my apple account on the first boot up with internet! Good stuff

DO NOT PURCHASE WITH YOUR MACBOOK OR OTHER APPLE DEVICES
Style Name: MacBook Air 13" (M4), Configuration: 3 years, Style Name: MacBook Air 13" (M4), Configuration: 3 years
I bought this along with my MacBook. And here is why you SHOULDN'T: 1. They NEVER sent me an AppleCare+ Agreement. You will only be able to download a General Terms & Conditions file. 2. I bought: AppleCare+ for 13-inch MacBook Air (M4) (3 years) and in the General Terms & Conditions that I downloaded, looking for my AppleCare+ Agreement #, it NEVER mentioned Macbook Air as a covered device. It was meant for other smaller devices, which is why it's cheaper. 3. Like I mentioned, since I never received an agreement, I never got an agreement #. 4. Since this AppleCare wasn't actually meant for a MacBook, it didn't connect automatically to my computer. So when I went to talk to Apple and Amazon, without an Agreement # you can do ANYTHING. If you purchase it, read through your General Terms and Conditions and find an excuse to ask for a FULL REFUND. Since this didn't cover my computer, I was thankfully able to get one, but it was a pain trying to talk to customer support and apple.

It worked! Apple Care was added to my device when I received it!
Style Name: MacBook Pro 14" (M4 Pro/M4 Max), Configuration: 3 years
I purchased an MacBook and AppleCare+ at the same time. A day/two after the purchase I received an email from Amazon that the AppleCare+ was in software and go to digital download. When I downloaded it was just the agreement. Then I started reading all the negative reviews on nightmare experience with Amazon and AppleCare+ not being added. I was very nervous and mentally prepare for the nightmare that lie ahead which having to call Amazon multiple times and then having to call Apple multiple times. To my surprise, right after Amazon delivered the MacBook (I got notification your item was delivered) I got another email from Amazon that AppleCare+ was added the laptop with agreement number and serial number of the laptop I received. I checked Apple's coverage site and sure enough Apple site showed AppleCare+ coverage tied the MacBook. I didn't even open the box or turn it on and see the AppleCare+ coverage. Hopefully this gives some insight to future buyers of AppleCare+ from Amazon!!!

DO NOT PURCHASE APPLECARE+ THROUGH AMAZON (Please read before making a decision)
Style Name: MacBook Air 13" (M4), Configuration: 3 years
I rarely write reviews like this, but DO NOT PURCHASE APPLECARE+ THROUGH AMAZON. Just over a month ago, I purchased an Apple MacBook Air (m4) with AppleCare+. The AppleCare+ wasn't populating on the laptop, so after calls with Apple Support and Apple Agreement Administration, they found that AMAZON sent them the approved agreement with the device serial number then abruptly canceled it the following day. This happened over a month ago, and I was not notified nor have I received a refund. I would not have known it was canceled if not for Apple Support and Apple Agreement Administration. The only recourse is to receive a refund from Amazon--which is NOT automatic, I am fighting for this--and purchase AppleCare+ directly through Apple. Had all this taken place after the 60-days purchasing the MacBook Air (I'm currently one week short of this deadline), then I would be SOL on being able to cover my device. PURCHASE AT YOUR OWN DISCRETION/RISK AND CHECK THAT APPLECARE+ IS APPROVED AND ACTIVE ON YOUR DEVICE. Otherwise, play it safe and activate directly through Apple.
