Big energy in the Boulderlamp shop right now!

Our production floor is packed wall-to-wall with LED grow lights, all staged and ready for shipment to a major Kentucky cultivation facility. This is what scaling American manufacturing looks like—real products, built by hand, moving out in volume.
There’s something satisfying about seeing weeks of work lined up and ready to roll onto a semi. Every unit represents precision, performance, and a commitment to helping growers maximize yield.
Proud of the team. Proud to build in the USA. More to come. 🚛💡

Not just fresh — these radishes started growing again.

I’ve been experimenting with radishes in our VioShield™ jar. I bought them at a local grocery store, trimmed the leaves, and placed them in the jar with an Integra Boost 62% RH humidity pack

The 405 nm light was on for 5 hours initially, then about 1 hour each day after that. After 6 days, I noticed something unexpected: not only were the radishes still fresh — they were sprouting.

That caught my attention.

It suggests that the combination of controlled humidity and 405 nm non-UV violet-blue light may do more than simply preserve freshness. It may also help maintain the living quality of produce during storage.

Freshness is one thing. Seeing produce still active after days in storage is something else.

Longer-lasting tomatoes… taste better too!

About a week ago, I shared a post: “My friend Andy shared a photo of tomatoes stored inside a VioShield™ jar for 14 days- still fresh like day one.” He followed up with something even more interesting — he said the tomatoes actually taste better. That got me curious.

I’ve tested strawberries and lettuce in the VioShield jar, but not tomatoes. So, I did some digging and came across this scientific publication: “Antifungal action of 405 nm light emitting diodes on tomatoes…” (Chua, Chong et al., 2021, Postharvest Biology and Technology)
In simple terms, the study found:
• 405 nm light significantly inhibited mold growth (1.9–3.2 log reduction)
• Tomatoes exposed to the light showed higher antioxidant levels and vitamin C (+24.6% phenolics, +28.2% antioxidant capacity, +16.5% vitamin C).
In other words — not just longer-lasting tomatoes… potentially better ones.

No wonder Andy thinks they taste better. 🍅

A last-minute code requirement almost derailed this install—70% open space for sprinklers.
We’re supplying a large number of MoonWalker series LED grow lights to a cannabis facility in Kentucky, and this unexpected constraint forced a rapid redesign. To comply, we split the LED driver housing into two sections and mounted them above the LED bars—maintaining performance while meeting code.
A complex engineering and logistics challenge on a tight timeline. Because Boulderlamp designs and builds in the USA, we moved quickly and kept the project on track for completion by the end of April.
If you’re facing facility constraints or strict code requirements, let’s talk—we engineer lighting solutions that adapt.

16 years of innovation and excellence.

In the news: “Aspergillus scare prompts Arizona ma*****na product recall” (kvoa.com, March 18, 2026). Recent recalls highlight an ongoing challenge in agriculture and storage — fungal contamination. Aspergillus, a common mold, can trigger allergic reactions or infections, particularly in vulnerable individuals.
In yesterday’s post, I shared how the VioShield™ antimicrobial jar helped keep tomato fresh for weeks. The same 405 nm non-UV violet-blue light used in VioShield has been shown to inhibit microorganisms — including Aspergillus niger — by inducing oxidative damage to spores and hyphae. With proper use (e.g., several hours of light exposure), VioShield is designed to significantly reduce microbial risk.
For those interested in science, see the peer-reviewed study: “Lethal effects of high-intensity violet 405-nm light…” (National Library of Medicine, 2013).
Smarter storage isn’t just about freshness — it’s about safety.

VioShield Jar – Freshness In. Mold Out.
We’re excited to finally bring the VioShield™ antimicrobial jar to market. This morning, my friend Andy in Colorado shared this photo: Day 14 — homegrown tomatoes stored inside a VioShield jar… still fresh like day one. How?
• ~60% RH humidity pack
• Just 1 hour of 405nm non-UV violet-blue light
No chemicals. No preservatives. Just smarter storage
