EDC FLASHLIGHT Titanium Polished Alien Black Clip Zirconium Ring Dark-Ti button   EDC Custom FLASHLIGHT SPECIFICATIONS: LED EMITTER: (3) Nichia NVSL219C D240 4000K 90+ CRI LEDs on 20mm 3XP MTN DTP Copper MCPCB. This is Nichia's newest emitter, which combines great color rendition with excellent output. DRIVER: 17mm DrJones H17Fx Driver w/ lucidrv2 - 7135 + FET Dr. Jones H17F (3V-4.35V Input Voltage, Triple-Channel Output). This super-advanced driver, designed by DrJones, is extremely advanced, with triple-channel output (2x7135 channels; 1xFET channel), seamless temperature sensor function and full user programmability. Mode Groups: the light off when it reaches the temperature you desire. Low modes (up to 13%) are driven by a single AMC7135 IC (380mA), which allows very low moonlight/firefly modes and makes those modes also quite efficient (the LED is more efficient at lower currents). Medium and high modes up to 3.0A are driven by additional 7*AMC7135. The direct drive FET allows for turbo modes of 5A and more - but that depends on the battery (use a high drain cell with low internal resistance) and on internal resistaces of the flashlight (contacts, wires, springs, switch, and the forward voltage of the LED). OPTIC: 10507 Carclo Lens - 3-UP Narrow Spot Optic BATTERY: 18350 1200MAH 10A HIGH DRAIN RECHARGEABLE BATTERY - included SWITCH: Complete Reverse Clicky Bypassed Switch with CNC machined precision metal knob as stated above. O-RING: standard silicone WINDOW: Watch Crystal Mineral Glass Crystal 22mm x 1mm MATERIALS: as stated above DIMENSIONS: 3.35in x 0.98in MADE IN USA WATERPROOF: yes DRIVER (More detailed info): 17mm Diameter 3V-4.35V Input Voltage Triple-Channel Output 2x 7135 Channels; Up to 3A Constant Current Regulation 1x FET/Direct Drive Channel; Non-regulated Output   Titanium metal is a very durable metal because it is corrosion-resistant: sea water, aqua regia, and chlorine. It is 40% lighter than steel but as strong as high-strength steel. Titanium finds applications in things like aerospace and surgical applications. Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color.       PRECISION: Each MetonBoss item is precision CNC machined from a solid bar in my Anaheim manufacturing facility in California, USA.   EVERY DAY CARRY - LIFETIME WARRANTY   We appreciate your support and love for MetonBoss EDC products, including Knife Scales and Hardware, Lanyard beads, Prybars, Flashlights, Pill boxes, Haptic Coins and Fidgets, Worry Coins and Spinning Tops!
