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

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.

Must have!
Color: Pale Gray, Pattern Name: Mouse, Color: Pale Gray, Pattern Name: Mouse
After using the MX Master 4 for a few days, I can honestly say this is one of the best mice I’ve ever owned. The ergonomic shape feels incredibly comfortable during long workdays, especially if you spend hours at a computer. The scrolling is smooth, the clicks feel premium, and the customization options make multitasking so much easier. The battery life is excellent, and switching between devices is seamless. It also looks very clean and modern on the desk. Definitely feels like a high-end productivity tool rather than just a basic mouse. Expensive? Yes. Worth it? Absolutely.

Great mouse, but not a huge leap from previous MX Masters
Color: Pale Gray, Pattern Name: Mouse
I’ve used pretty much every mouse in the MX Master series over the years, so I had a good idea of what to expect going into this—and overall, it’s still a really solid mouse. The ergonomics are excellent, just like the previous versions. It fits the hand really naturally and is comfortable for long work sessions. That’s honestly one of the biggest reasons I keep coming back to this lineup. The scroll wheel is still a standout feature. The ultra-fast scrolling is incredibly smooth and makes a big difference when you’re going through long documents or web pages. Switching between free spin and precision scrolling works flawlessly. Build quality is top-notch as expected. Everything feels premium, from the materials to the button clicks. No complaints there at all. That said, if you’ve already used previous MX Master models, this doesn’t feel like a major upgrade. It’s more of a refinement than anything new or groundbreaking. It does everything well—but it doesn’t necessarily wow you if you’re coming from something like the MX Master 3 or 3S. Overall, still a great mouse and easy to recommend—especially if you’re new to the MX Master series. But if you already have a recent model, just know this is more of an incremental improvement than a big jump.

Quality materials, great mouse
Color: Graphite, Pattern Name: Mouse
I have gone through many mice looking for one that feels 'just right'. This is it. The shape is perfect for my hand, the haptic feedback is nice, if not very useful to me, and the smoothness with which it moves across my pad is well worth the price alone. Nicely configurable in the Logi app. One note - It's fine for me, but this is a very large mouse.

One Mouse to Bind Them, in the Long Hours of the Desk
Color: Graphite, Pattern Name: Mouse
It was the winter of the endless scroll, when the days in River Grove stretched thin and pale as old parchment and the light from the monitor became the only sun we knew, that my old mouse—poor, faithful thing—began its slow betrayal. Clicks faltered like the last breath of a dying Rohirrim steed; the wheel spun loose and reckless, sending spreadsheets cascading into chaos as though the very order of Middle-earth had unraveled; the cursor wandered with the aimless grief of a man who has lost his king. I sat there in the dim room above the garage, wrist aching like the shoulder that once bore the weight of Andúril, staring at the screen while deadlines crept closer, silent and inexorable as the shadow over Mordor. Then the Logitech MX Master 4 arrived, graphite-dark as the armor of Isildur’s line, shaped not for haste but for endurance, its curves rising like the hills of the Shire remade for the hand of a weary scribe. I took it up and felt the weight settle—not heavy, but certain, as though the mouse itself understood the gravity of long labor. The MagSpeed wheel turned under my thumb with the smooth inevitability of the Anduin in flood, ultra-fast when the document must race to its end, precise when a single pixel demanded mercy. The haptic feedback thrummed beneath my fingers like the deep pulse of the earth when the Ents march—subtle, insistent, alive. Every scroll, every gesture carried the quiet authority of a thing forged to outlast lesser tools. It paired without ceremony—Bluetooth to the laptop, Logi Bolt to the desktop—crossing between machines as swiftly as the Eagles bore Gandalf from the tower, no fumbling, no oaths sworn in frustration. The side buttons waited like loyal vassals: one to summon the hidden application switcher, another to gesture across screens as though drawing maps of realms unseen. The gesture button itself became my quiet command—thumb pressed, fingers sweeping, and windows arranged themselves in obedient array, the way the hosts of the West might have arrayed themselves upon the Pelennor Fields. And when the battery whispered low, the USB-C cord drank from the wall like a pilgrim at the fountains of Imladris, three hours of life from a single minute’s charge. I have worked with it now through the gray mornings when the snow muffled every sound outside, through the late nights when the house slept and only the cursor moved, through the sudden urgent revisions that once would have left me cursing the heavens. It does not slip. It does not tire. It endures, as the light of Eärendil endures above the storm, a small fierce companion against the gathering hours. If your days are measured in documents and deadlines, in the slow turning of wheels both literal and metaphorical, take this MX Master 4. It is not mere plastic and circuit; it is covenant between hand and machine, a shield against the tedium of the long watch, the fellowship your desk has hungered for in its quiet exile. Ten stars out of five, though the heavens ration light to fewer. I would carry it into the Cracks of Doom itself and fear no misclick. 🖱️🧙‍♂️📜🌑

Almost Perfect
Color: Graphite, Pattern Name: Mouse
If you are looking for a quiet mouse, this is it. I was skeptical about the "ergonomics" but find that it is much more comfortable for me than the more traditional design for left and right clicking. Simple moving seems fine but its weight is a bit excessive for lifting for repositioning in tight spaces. It is difficult to lift without activating the button on the haptic pad, even set to require firm pressure. A bit more contour on the right would solve this nicely to allow lifting the mouse without repositioning your hand. The forward and back buttons may be a bit awkward for some people. I'm slowly adjusting. Actually, each mouse I've owned needed a bit of getting used to. Side scrolling doesn't always work as it seems it would. Frequently, it scrolls vertically like the "normal" scroll wheel depending on the program. Haptic feedback is not a commonly used feature yet, however, Windows will be slowly adding haptic features to later updates from what I've read. I keep the setting on the lowest haptic feedback level and for what it functions on so far seems natural and not intrusive. There are many adjustments and customizations, too many to go into since I haven't played around with most. So far, even with what may seem like a lot of negative thoughts, I love this mouse. It would be five stars if lifting to repositioning in tight spaces was easier.
