MAINFRAME Max 365 - 12W 365nm UV Flashlight, 21700 Rechargeable

🔦 MAINFRAME Max 365 – 12W 365nm UV Flashlight, 21700 Rechargeable

The largest light in the 365 series and the strongest: a 12W driver behind a four-core 365nm emitter, running on a 4000mAh 21700 for roughly eight hours per charge. Single mode, UV only. Charging is through a hidden rotary port – twist the body and the USB-C connector is underneath, so there is no rubber flap to tear off.

Where it sits in the lineup: the top of the range – fourth of four, and the largest. Three smaller lights sit below it (the AAA Pico, the BLACKSITE Compact 365 and the HEXNODE Mid 365) and nothing above. Biggest cell, strongest driver, longest runtime: this is the one you reach for when the job is bigger than a pocket light.

✅ Key Features:

• 💡 4-Core UV Emitter: 365nm, 12W driver for strong, consistent output
• ⚡ Single Mode: one button, one output, UV only – no modes to cycle through
• 🔋 21700 Battery Included: 4000mAh, the biggest cell in the series
• 🔌 Hidden Rotary USB-C Charging: ~6.5 hours to full, ~8 hours of runtime
• 🚿 IP44 Splash Resistant: handles rain and incidental splashes
• 💪 1m Drop Rated: aluminum alloy body with reverse-polarity and overcharge protection
• 🔎 Filter Included: built-in UV-pass lens
• 📏 Full Size: 170mm long, 45 × 31mm across – 192g
• 🎒 In the Box: USB-C cable, lanyard, storage pouch

🔬 Common Uses for 365nm UV Light:

• ✅ Banknote and ID inspection
• 🧪 Mold and fluorescence detection
• 🏺 Mineral and antique authentication
• 🚗 Automotive UV leak-dye inspection
• 🧼 Pet stains, leaks and cleaning verification
• 🔧 PCB inspection and UV resin curing

🗣️ In Simple English:

This is the big one. Bigger battery, stronger driver and longer runtime than anything else in the range, with a cable, lanyard and pouch in the box so it is ready to work out of the packet. Reach for it when you are covering a whole engine bay, a whole room or a whole afternoon rather than checking a single banknote. Note: the manufacturer lists both a 12W driver rating and a separate "4.11W output" figure without explaining the difference – treat 12W as the electrical rating, not a measured radiant-flux output.

🪜 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.
• 🔦 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. (You are here.)

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.
