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.

Real steel pipe
Size: O Desk Unfinished 3/4-in and 1/2-in
This pipe table leg set was great. It's real steel pipe like from the hardware store. It does have a layer of oil on it so that must be stripped using dawn or some other degreaser before handleing and painting. It is also offset in the middle bar so if you use it as a desk you get more leg clearance. I used it as a table base so I bought matching middle braces to set the middle support in the center of the table. Once together it looks great. I highly recommend getting this if you want a good quality pipe base.

Price / Quality - Office Desk - Perfect
Size: H Desk Unfinished 3/4-in and 1/2-in
Purchased two sets to create a custom L shaped desk for the office. Placed a pine stained top. Perfect to handle a monitor, multiple laptops, normal office equipment. Extra benefit is the cross piece at the bottom as a foot rest. Very sturdy while sitting on carpet. Compared to normal pipe material purchased in large box store -- could not have asked for a better product for the price. Looking at other products for additional projects for around the house for the product and vendor. - Highly Recommend.

Fantastic style, good stability, customizable finish, and great customer service
Size: M Desk Unfinished 3/4-in and 1/2-in
Put this together in about April 2020 right about the crazy lockdown/quarantine/work-from-home timeframe. I knew that I wanted a simple hardwood desk with no drawers or stuff below the top. I have an ergonomic keyboard tray that I have attached to all my work desks for many years now, and it was too long for my old home desk, which was also made of MDF and was falling apart. Boo. Enter this kit plus a butcher block top from the big box store. This kit went together easily. I had lost the instructions but a quick email to the JS Supplies company, and they hooked me up. By the time they sent it, I had actually figured out the part that was puzzling, which was what the all-thread pieces were for (the couplers between the elbows and the flanges on the top side). I degreased all the parts with a simple Simple Green-type solution diluted in a 5 gallon bucket. I then sprayed the pieces with a satin nitrocellulose laqcuer (Minwax brand that I got from the home improvement big box). Worked great. I thought about doing a sealed rust finish using a science project volcano--vinegar and baking soda for a quick layer of rust on the outside--but I decided against it, as I wasn't sure of how stable the final product would be, even after a clear spray finish. The satin nitro finish looks great without even looking like a finish. I also coated the pieces with paste wax after the finish dried, just for good measure. The one thing that is a bit disappointing is the stability... WITH MY TOP, mind you.I should be clear that the top that I'm using is a 1-3/4" thick monster piece of birch butcher block that is 60" x 30". I'm guessing that it's 40-50 pounds? Maybe more. This is probably WAY more weight than this leg set is made for. I also have the aforementioned keyboard tray that sticks out (torque equals force times lever arm) and causes even more torque. I get some shaking with the top with this setup. I have the desk on carpet; I was concerned that maybe the carpet and pad were not giving enough stability with the feet, so I made some plywood platforms for the feet. I also carefully leveled the feet to make sure it wasn't just uneven legs that was causing the instability. Still shakes no matter what I tried. I think it's just that I have such a heavy top--more than this thing is spec'd for. That's totally fine, and I don't want to knock off a bunch of stars for that. I leave these comments more as a "don't do what I did" thing. Just be advised that you need to limit the weight of the top to something reasonable. The design of one upright on each side of the desk with a pipe coupler in between is probably the weak spot with my heavy desktop; I'm thinking of either adding tension on either side (with some threaded rod and turnbuckles) or some extra supports with something like the Steel-Tek pieces from Lowe's. Overall, I'm very satisfied with the product and the company!

So nice I bought twice!
Size: H Desk Unfinished 3/4-in and 1/2-in, Size: H Desk Unfinished 3/4-in and 1/2-in
For starters, this is a great buy if it is exactly what you want. For me that was the case and it would have cost me a good $40 or more to replicate it at a big box store. With that said, if you are not planning on using all of the pieces and want a different configuration, this may not be the kit for you. All of the parts inside are just like if you bought it at a local home improvement store. All the pipes need to be cleaned and protected. I personally found that dish soap (dry off immediately after you clean a piece) was the easiest to clean everything and I finished it with some wax. The kit is sturdy and easily supports the weight of my butcher block tops. I inverted the kit as it is designed as I intend on adding a shelf and am planning on using the support brace to aid in holding that shelf up for cable management. After cleaning and protecting, putting the kit together only took 5-10 minutes and that was with kid disruptions. I purchased 2 so that my wife and I could have matching desks in the office and I couldn't be happier.

Durable and sturdy. I bought two
Size: H Desk Unfinished 3/4-in and 1/2-in
Love the kit. I ordered two to make an L-shaped desk for my home office. Perfect height, looks cool, and sturdy. Slightly tricky to get two of them to the exact same height but you can adjust them buy loosing/tightning parts. Way cheaper than going to the hardware store and buying the same parts. I wiped each piece down as they are a bit dirty/greasy, but no big deal.
