BLACKSITE Compact 365 - 18650 UV Flashlight, USB-C Rechargeable

🔦 BLACKSITE Compact 365 – 18650 UV Flashlight, USB-C Rechargeable

A slim 365nm ultraviolet inspection light with a built-in 18650 cell and direct USB-C charging. Single mode, UV only, behind a dark UV-pass filter lens – so it looks like it is barely switched on until the beam crosses something fluorescent, and then that thing lights up and nothing else does.

Where it sits in the lineup: one step up from the AAA Pico. Bigger cell, more output, still pocket-sized – with two larger 21700 models above it if you need more reach.

✅ Key Features:

• 💡 365nm UV LED: single-mode UV-only output, 3W driver
• 🕶️ Filtered Output: dark UV-pass lens cuts the visible violet spill so fluorescence stands out
• 🔋 18650 Built In: 800mAh cell included, nothing extra to buy
• ⚡ USB-C Direct Charging: ~2.5 hours to full, ~3.5 hours of runtime
• 💪 1m Drop Rated: aluminum alloy body, tail-cap reverse switch
• 📐 Compact: 113mm long, 24mm across, 71g with the cell installed

🔬 Common Uses for 365nm UV Light:

• ✅ Banknote and ID inspection
• 🧪 Mold and fluorescence detection
• 🧼 Pet stain detection
• 🏺 Mineral and antique authentication
• 🔧 PCB work and UV resin curing

🗣️ In Simple English:

One button, one mode, one job. It charges off the same USB-C cable as your phone and keeps its battery inside, so there is nothing loose to lose. Because the lens is filtered, the beam itself stays dim and purple – that is the point. You are not looking at the light, you are looking at what the light makes glow. Good for a quick bill check, hunting pet messes, checking minerals, or curing resin.

🪜 Where This Sits In The 365 Ladder:

Four sizes of the same idea – true 365nm, single mode, UV only. Pick by how much ground you need to cover, not by guessing at spec sheets.

• 🔦 AAA Pico UV – single AAA, pen-sized – the one you actually carry.
• 🔦 BLACKSITE Compact 365 – built-in 18650 and USB-C, filtered lens – pocket-sized with real output. (You are here.)
• 🔦 HEXNODE Mid 365 – midsize 21700 with a seven-emitter hex array – a wide flood instead of a spot.
• 🔦 MAINFRAME Max 365 – the big one – 12W four-core emitter on a 4000mAh 21700, for when the job is bigger than a pocket light.

All four live in the GCS Exclusive UV collection.

Note: 365nm UV is invisible to the eye but still UV. Don't look into the lens or point it at anyone's eyes or skin.
