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.

Long lasting scent and has not been destroyed by my heavy chewer.
Size: Jumbo, Style: Bacon
My medium puppy loves this ball. She already has the smaller size but appears to enjoy the challenge of catching the large one. An added benefit is it's easier for me to win it back when we fight (play fighting) for it.
The scent really lasts. I've had the smaller version for a few months and the scent is still there. Does it really smell like bacon? Not to my nose but the puppy thinks it's awesome.
The ball itself is really tough. The pup can destroy a tennis ball in a day. Except for a few teeth marks these balls are holding together great.

Worth every penny—my beagle is obsessed
Size: Medium, Style: Cheddar Cheese, Size: Medium, Style: Cheddar Cheese
No dog toy is indestructible if you have a hound or a pit. I happen to have a combination of both. This toy is the best $12 you could possibly spend for a dog that likes to “kill” their toys. The only reason I’m buying more is because I keep losing them.
My dog is a rescue. She’s half beagle, a quarter boxer, and a quarter pit bull. She’s a tiny fire-cracker and I lover her to pieces. And she loves tennis balls to pieces. Literally.
She adores tennis balls, squeaky toys, and food. She will absolutely try to surgically extract the squeaker from any toy she gets because she has a high prey-drive. These balls last usually at least a week before she manages to dislodge the squeaker or puncture the squeaking mechanism, but I still have one I got about six months ago that has the paint worn off and it still squeaks.
This ball literally has everything. It squeaks, it bounces pretty high, it looks like a real tennis ball so my girl recognizes them as “toy” immediately, and they smell good.
These balls in particular last forever. I got her a can of regular tennis balls and she had them in four pieces within 10 minutes or less, which is not healthy for her because she likes to eat the pieces. For this dog toy, I have never seen her crack it. She’s pushed the squeaker inside of exactly one of them so far, and it stayed inside the ball. Much safer than a toy that she can possibly ingest.
The toys come in several colors, but it’s not just to make them look cute and colorful. The colors correspond to flavors, as each of the balls has a different scent. I’ve sniffed them and noticed there’s a mild food smell beneath the rubber scent. I can tell that dogs really do get a kick out of the “flavors.”
I’ve taken these to the dog park and all the dogs want the Playology tennis ball, even if we have other generic balls flying around. My dog even has favorites. We have a muscle-head pit bull/staffy mix at the park who is a giant meat-ball. He got his hands on one of these and he wasn’t even able to break it open for at least 20 minutes of deliberate chewing.
My girl’s favorite “flavor” for a long time was beef (the red one). The blue “peanut butter” flavor is the easiest one to find in stores. She was obsessed with a purple one for a while, apparently it was bacon flavor. I couldn’t find that one! I saw that Amazon has an orange “cheese” flavor and knew she’d love it. She’s obsessed.
I really wanted to leave this review to convince people to invest in this product. Your dog will be so happy, and this company made something great.
I’m worried because I went on their website yesterday and they had only one or two colors available. I don’t want them to stop making this amazing toy. I hope they don’t lose business because their product is TOO durable!! If they make more flavors, or maybe make some multi-dog (tug ropes?) or similar, I’ll definitely continue to be a customer. Please keep making these awesome tennis balls!

Not Squeakable for Mini/Toy Aussies
Size: Medium (VALUE 2-Pack), Style: Chicken
Very durable and good squeaker. However, too large and hard for my Mini Aussies to squeak. My Aussies love their squeaky toys, unfortunately not this one.

Not indestructable, but very sturdy
Size: Medium, Style: Beef
I have recently been blessed (and cursed) with my first Super Chewer dog, a year old Australian Shepherd. She will chew herself out of boredom, so it's imperative we always have sturdy toys readily available for her, preferably in every room.
Playology and Kong by and large have been the best toys we can find for her. Kong has a very good rubber ball, bone, and ring that have held up spectacularly (no noticeable damage after months of use, except maybe some pin-prick teeth marks). Dogs need a wide range of textures though for enrichment, so we've been dabbling with the Playology line (the tire, plush bone, dry-tech rope), including this ball.
The scent factor is definitely interesting. Most people know Playology for the peanut butter scents, so I was very excited to find a multitude of flavors available on Amazon, especially with the different scents clearly labeled. I choose the red or beef flavored since the only two in the medium size in stock at the time were beef and sweet potato. The scent is indeed noticeable to humans, but it's not too strong or overwhelming on its own (walking down the Playology aisle in Petsmart can be overwhelming though since they have dozens of dozens of scented toys, much like going down a candle aisle).
I can't speak for the dog on how she feels about the scent, but she took to the ball immediately, same as the normal peanut butter ones we get. The medium size is pretty much perfect for her (she's just under 50lbs). It's got decent bounce for playing fetch in the house, but not so bouncy that we're afraid to use it in the house. It's got a decent density to it as well that adds to the sturdiness.
The biggest issue is the squeaker. It's not an obnoxious squeaker by any means, and the dog enjoys it very much. However, when you put a squeaker in any toy, it reduces the density and creates a weak spot dogs can exploit. She did good with the ball at first and was able to sit and chew on it for minutes as a time without doing any real damage (her teeth leave lots of pin-prick teeth marks, but they don't do any real damage to the ball, just superficial marks).
Aussies are considered incredibly smart though, and it didn't take her long to learn she could rip out the bottom of the ball where the squeaker is sealed inside to tear the squeaker out, thus ripping the squeaker apart and compromising the structural integrity of the ball. We're debating if we want to toss the ball in the trash or attempt letting her play with it in a supervised session without the squeaker to see if it is safe.
So, overall, this is a very tough ball. It does accumulate teeth marks that are essentially harmless, but there is a weak spot in the seam where the squeaker is inserted, which means this is not indestructible. It is by and large a great ball for fetch and likely won't ever be destroyed unless a dog is left with it long enough to chew a hole through that squeaker seam. Playology balls are pretty costly though, so the risk of it becoming unusable once the squeaker is ripped out is a bit off-putting. The bright side is that if you monitor your dog, you can likely get several weeks or months of use out of the ball; just no unsupervised play sessions.
7/10, durable, bouncy, and the scent keeps the dog interested, but the ball is not good unsupervised as it can be destroyed if the squeaker is ripped out. We will continue to buy Playology toys, but we will likely not buy too many of these balls until a more durable one (maybe without a squeaker) is released.

No. Just no. My own dog shamed me…
Size: Medium, Style: Beef, Size: Medium, Style: Beef
My German Shepherd likes squeaky balls. She has lots of them. Most are similar to a tennis ball. By the way, don’t give your dog an actual tennis ball. The outer material is made for grip for tennis. It’s abrasive and is not good for your dog’s teeth enamel at all.
Anyway, for $14.99, I thought I’d give this one a try. The pictured packaging alone was an eye grabber. The picture you see on Amazon is a cardboard with item specific info on the card: flavor, size, what it is (squeaky ball). The pictured product also has a hole in the card to secure and present the item the card describes. Even two color coded red zip ties securing the ball in the card hole. Awesome presentation and frankly that’s what made me give this a shot. So, as far as the presented product/packaging on Amazon, great job! I even sent a link to a buddy and he bought one too.
Well, I cannot speak for everyone, but what I received was what’s pictured with my review. A red ball in a clear bag, along with a card that describes the product line. Nothing specific to what I actually bought (like the slick item-specific packaging on Amazon. To find that, I had to read the condensed description on the Amazon specific bar code that is right on top of a different barcode. This kind of thing displeases me. I want what grabbed my attention on amazon. No, this was not a return. This is how they come.
I figured with item specific info on the packaging, the company is putting some money into packaging that makes you feel like you bought something specific. Pictured one says all natural beef. The chicken one says chicken. Pictured one says the size. Heck, I’d of been happy to at least have the ball attached to a card that at least says it’s a squeaky ball. Nope.
Cost cutting is not ok when you are selling a beef flavored, medium size squeaky ball for $14.99.
What arrives is an advertisement for the whole line, nothing that says what it is, the flavor, the size (unless you try to make out the Amazon bar code desc). Just a ball in a bag with an advertisement to buy other stuff they make.
Maybe you received what’s pictured. I texted my buddy and asked him what he received. The exact same thing I did.
In my opinion, when one cuts corners on packaging, I have no doubt corners could have been cut with the product itself. The squeak isn’t as easy as kong ball squeaker. Takes effort. So if your dog likes to play by walking/running around while constantly biting and getting that pleasing squeak each time, that didn’t happen here. Yes, I know the tennis ball type squeakers are different. But this says it’s a squeaker ball. Not just a squeaker ball, but a flavored squeaker ball. Mine smelled like rubber. Where’s the beef?
I threw it a few times. My dog chased it a bit, did her usual “what’s this” evaluation, bit into it a few times with her very strong jaws, only to have no squeak. God as my witness, she dropped it, looked at me with what I insist is a look of disappointment, and walked away. She then went to the big bin of a huge variety of squeaky balls and grabbed one. She then went upstairs, with a squeak every second or so as she went up.
I went and picked this one up with slobber and all. To get this to squeak requires opposing thumbs. So I suppose it could be marketed as a hand strengthener that squeaks.
Friends lab had zero interest as well. So, I’m gong to actually return a dog toy. This was a disappointment. If it had come carded the way it shows on Amazon, I would not be as frustrated. I won’t take a chance when corners are cut when it comes to my dog. Update the picture to what I received is my advice to the company. I have a feeling what I got wouldn’t sell as easily.
Topping it off, I noticed something odd. It doesn’t squeak when squeezing it, only when it is released to go back to its regular shape. So it’s a reverse reward. Weird. All the squeaker balls we have make a noise both when squeezing and releasing.
Sorry Olina (my pooch).
