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.

After all, chidren are good inside.
Format: Kindle
Parenting is about how parents treat their kids. One important aspect of what counts for good parenting is how we face the kids’ negative behaviors. When we were children, our parents did not respect our emotional needs. They only scolded us when we were naughty. After we become parents, we treat our kids the way our parents treated us. Dr Becky proposes in this book, contrary to what our parents thought, children are all good inside and thus we should treat children’s bad behaviors as if their misbehaviors are signs that they don’t know how to express their needs. With this assumption, there are three implications for parenting. First, as children are good inside, what they do outside should not be our focus. Whether it is emotional tantrums, not listening, aggressive tantrums, sibling rivalry, rudeness and defiance, whining, lying, food habits, parents should not pay too much attention to it. Instead, parents should see the cause that contributes to the resulting negative behavior. Take whining as an example. Whining, according to a Cambridge dictionary, means ‘to make a long, high, sad sound’. As parents we are easily annoyed by whining and we quickly think that kids are disrespectful. In Dr Becky’s view, whining=strong desire+powerlessness. Children whine because they feel helpless and ‘indicate they feel alone and unseen in their desires’ (p.188), rather than because they are arrogant. What does this imply? Do we have to give in, knowing that they are desperate for connection and feeling powerful? The answer is no. Dr Becky said ‘while our job as parents is to make decisions that we feel are right for our kids even in the face of protest, we can still practice understanding and connecting’. While saying no, which they probably know they do need, at the same time we can give them the sympathy they also need. Thinking that kids are bad inside often leads to power struggles or arguments when we request them to request in an appropriate tone again. Kids are good inside, and thus we should focus our attention on how to respond to their helplessness rather than their whines. Secondly, not only should we not focus on their outside behavior, we should also be aware that what is on the surface often contrasts with what the kid feels inside. One of the most-feared emotions we are afraid to see children have is anger, also known as tantrums. When children are angry, they display undesirably violent behaviors such as hitting others. Dr Becky points out that they hit not because they are angry, but because they are scared. When we adults are afraid, we may also kill people if we are irrational. Children have not yet developed their prefrontal cortex which is responsible for logic and language, and so the most severe reaction they can possibly express is through tantrums. We may wonder why children are afraid: they are “terrified of the sensations, urges, and feelings coursing inside their body” (p.158) such as frustration and anxiety. These feelings which adults are used to feel scary to kids. Naming the right emotion is the first step to solving the problem and helping kids to cope with it. Only after we identify correctly the emotion the children are experiencing can we as parents exert the right method to deal with the out-of-control behavior. Clearly we know reprimanding our kids is not correct because “they are good inside”. To stop the kid's aggressive tantrums effectively, parents should assert their authority. Parents should show the confidence that they are in charge of the situation. Then, the next critical step is to maintain the kid's safety. Regardless of how the kid feels, the parent should stop the dangerous behavior the kid is engaging in, which Dr Becky calls containment. She says it best: “kids don’t feel good when they are out of control”. That we assert our authority and contain even though kids are not happy on the surface is an act of love, maturity, and responsibility. If we don't, not only will it cause injury, it will make children think we evade responsibility, thus making them feel more overwhelmed. To conclude, as parents we need to know our roles and our kids’ roles. Our job is to keep our children safe, both physically and psychologically. We need to remember that a gap exists between kids’ abilities to feel and their abilities to regulate their feelings, and the gap manifests as deregulated behavior. While it is children’s job to explore and express their feelings, it is our job to help them regulate them by setting physical boundaries, validating their emotions, and being empathetic to their feelings. We are our kids’ role models. We are demonstrating to our kids the emotion regulation skills. As our kids are allowed to shout and protest because they are doing their jobs, we are also allowed to upset them when we set boundaries. We just need to remember that to do our job well, we must learn to connect with and understand them more because after all, children are good inside.

Good read
Very good basic subjective author. Some modern therapist offer a different perspective on rewards and child behavior, but to be expected in academia. As with any behavioral psychology observable or behavioral science documents - measure the subjective amount against the scientific controlling evidence being offerred. If no evidence - it is just subjective opinion.

Not JUST a Parenting Book
Format: Hardcover
Good Inside and Dr. Becky are everything the world needs now. A strong, sturdy perspective that truly, wholeheartedly believes in the good inside us all. That is truly not cheap talk. It. is. the. real. deal. This book is a parenting book that covers big picture philosophical understandings of parenthood AND the more practical, day-to-day implementation of said philosophies. Dr. Becky is incredible about explaining the underlying reasons for why kids do what they do and why WE respond as we do and then she talks us through exactly how to apply the "most generous interpretation" so that we can do better for the next generation AND for ourselves. Good Inside is also a REparenting book and a leadership book. She will teach you how to show up for the realness of your own life for yourself and for the kids that you love most dearly. Truly, there is not a better way to spend your money. Maybe go ahead and stock up on highlighters and your favorite pens too because, if you're like me, you will be highlighting and underlining left and right. It's truly that game-changing. Get ready to finally understand your job description as a parent and your kids' job descriptions as wonderful, little growing humans in the world. And if you yourself need healing from your own childhood, this will open the door for that too. I know that you, dear Amazon review reader, do not know me but I am not really prone to hyperbole. I do not feel it is an exaggeration to say that Dr. Becky and Good Inside is game-changing. This purchase is truly an investment in yourself and the kind of parent and person you want to be and an investment in your kids and their future.

Good advice overall
Format: Paperback
This is an interesting read to help with your child’s self esteem and behavior. The first several chapters on the psychology behind behavior were more helpful and interesting than the second half of the book that addresses specific behaviors. Also, if you follow Dr Becky on social media, most of her advice is already in her content. However, I’m glad I read this book, even it wasn’t life changing.

So incredibly helpful with sensitive kiddo
Format: Hardcover
This book has been so, so wonderfully helpful, my husband jokes it’s now my bible. Kiddo went from like 10-20 meltdowns a day to only a couple, and those are resolved in like a tenth of the time. I feel so much less frustrated and more connected, and able to handle it when he does dysregulate in a way that makes me proud. It’s also honestly been healing for me as a child of loving parents who nonetheless didn’t learn all this stuff and did a lot of invalidating and shaming. It’s great theory and very easily digestible and applicable practice combined. I wish I’d found it 3 years sooner and I can’t recommend it enough.
