GCS Exclusive UV

Everything at Gadget Connections that works in ultraviolet, in one place — the house-brand 365nm inspection lights plus the UV-adjacent gear that pairs with them.

🔦 The 365 Ladder

Our own 365nm series runs in four sizes, so you can choose by how much ground you need to cover instead of guessing at spec sheets. Every one is true 365nm, single mode, UV only — no white-light mode to fumble past, and no "395nm" shortcut.

• AAA Pico — keychain-and-pocket size on a single AAA. The one you actually carry.
• BLACKSITE Compact 365 — built-in 18650, USB-C, filtered lens. Pocket-sized with real output.
• HEXNODE Mid 365 — midsize 21700 body with a seven-emitter hex array: one LED ringed by six, for a wide flood instead of a spot.
• MAINFRAME Max 365 — the largest: a 12W four-core emitter on a 4000mAh 21700, for when the job is bigger than a pocket light.

🟣 Why 365nm And Not 395nm

Most cheap "UV" flashlights are 395nm, which is mostly visible violet light. You get a bright purple beam and very little actual fluorescence — the visible spill washes out the thing you were trying to see. True 365nm is nearly invisible to the eye, so the beam looks dim and underwhelming. That is exactly the point: you are not looking at the light, you are looking at what the light makes glow.

🔬 What People Use These For

• ✅ Banknote, ID and document checks
• 🧼 Pet stains, leaks and cleaning verification
• 🧪 Mold and general fluorescence detection
• 🏺 Minerals, gemstones and antique authentication
• 🚗 Automotive UV leak-dye inspection
• 🔧 PCB inspection and UV resin curing
• 🦂 Scorpion spotting after dark

UV invisible-ink marker pens, UV-charged glow-in-the-dark EDC, and multi-mode pocket lights that carry a UV channel alongside white and RGB.

Safety note: 365nm UV is invisible to the eye but it is still ultraviolet. Don't look into the lens, and don't point one at anyone's eyes or skin.
