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.

Works well!
Style: 16 oz
This stuff works well. I've only ever used it after my tires had been punctured and ran flat... I haven't had a flat this wouldn't seal... 3 uses so far all 3 have fixed flats and been many miles put on since the repairs. I start with as little as possible and if it doesn't seal I just add more, I think I've managed to use far less than recommended and successfully sealed punctures. I've only used it on fat tire e-bike tires. I'm pretty comfortable with the seal and I have no plans to replace the tubes, which saves me a fair amount of trouble. I will update if it springs any leaks without new punctures. It's very easy to use and actually pretty clean especially compared to automotive type tire repair foams. The first repair I used it for was a brand new bike that just wouldn't hold air in the rear, totally unsure what caused it to keep losing air but 2 or 3 small doses of slime fixed it. The most recent slime repair, I had a wobbly bike ride which felt weird and I couldn't figure out why but a few hours after I had returned home both tires were totally flat. They both had a handful or more of some really heavy duty thorns stuck in the tire that likely barely punctured the tubes but the rear tire also had a roofing nail in it. I did not think the slime was going to fill that one, it was a pretty heavy leak once I removed the nail, but Slime did seal it and I've since ridden the bike twice and in the same rough conditions I normally would still holding strong at higher pressure than I normally ride, have yet to drop back down since refilling but I am hoping and expecting it won't be a problem. Two thumbs up. I always keep a small tube in my bike bag and I am confident if I ever need it while I'm out and about it will be useful.

Who can live without slime great stuff and a good price. 👍
Style: 32 oz
If anyone has an outdoor anything that takes air. You should never be caught without this stuff. It seals your tires on almost anything and it lasts longer than you would expect. It’s easy to use and easy to clean up after using it. It will work well for anything that is supposed to hold air. Great product.

Title: Reliable, Easy-to-Use, and Worth Every Penny
Style: 32 oz
I’ve been using Slime tire sealant for my fat tire e-bike, and I can say with confidence that this product delivers exactly what it promises. The application is simple, the results are consistent, and the peace of mind it provides is invaluable. For anyone who rides regularly — whether for commuting, recreation, or deliveries — this is a product that pays for itself many times over. The first thing I appreciate about Slime is how easy it is to install. The bottle is well-designed, the instructions are clear, and the process takes just a few minutes. You simply deflate the tire, remove the valve core, squeeze in the recommended amount, reinstall the valve core, inflate, and spin the wheel to distribute the sealant evenly. No special tools, no mess, and no guesswork — just a straightforward, user-friendly process. Performance-wise, Slime does exactly what it’s supposed to do: seal punctures quickly and effectively. I’ve had nails, thorns, and sharp debris puncture my tires while riding, and in every case where the leak was within the tread area, Slime sealed it instantly. There’s something incredibly reassuring about hearing that faint hiss of air for a second, then watching it stop as the sealant does its job. It’s a real-time reminder that this product is actively protecting you from being stranded. What sets Slime apart from other sealants I’ve tried is its durability. Once applied, it stays active inside the tube for months, ready to respond to new punctures as they happen. It doesn’t dry out quickly, it doesn’t clump up, and it doesn’t cause balance issues with the tires. For someone who rides almost daily, that reliability is a huge plus. Another thing I respect about this product is that it’s non-toxic and environmentally friendly. If a bit of sealant escapes during a repair, I don’t have to worry about it harming the environment. It’s also water-soluble, making cleanup easy if I ever need to replace a tube or tire. That attention to safety and sustainability shows that the company isn’t just making a great product — they’re doing it responsibly. The value for the price is excellent. One bottle goes a long way, and when you factor in the cost of replacing tubes, paying for roadside repairs, or even the inconvenience of being late because of a flat, Slime is an investment in both savings and peace of mind. For delivery riders like me, it’s especially valuable — every flat avoided means another day of work uninterrupted. In short, Slime is one of those rare products that I can recommend without hesitation. It’s easy to use, effective, long-lasting, and backed by a company that clearly understands the needs of cyclists and e-bike riders. It has already saved me from countless headaches, and I plan to keep a bottle on hand at all times. If you ride regularly and haven’t tried it yet, you’re taking an unnecessary risk — this is one of the best preventative tools you can add to your maintenance kit. Verdict: Five stars for performance, ease of use, and overall value. Slime is a must-have for any serious rider who values reliability and wants to keep rolling no matter what’s on the road.

Slime is good, pump is a disaster
Style: 1 gal, Style: 1 gal
The only reason I am giving this a 4 star(not zero) rating is the slime itself. The actual pump on the 1 gallon canister is awful. It makes so much mess, so I do not know whether I pumped the slime into the tubes or it all just spilled out of the base of the pump. The bottles worked great, but this time I needed to use more slime for a bunch of tires. What a slimy mess that was. Very poor pump design. Only after I spilled who knows how much of the slime, I finally washed it and was able to see the problem. The cap at the base of the pump got unscrewed and let all the slime lose. I screwed it back up and this should fix the mess next time I use it. Just a heads if someone encounters the same issue.
