FourSevens Quark QK16L MKIII Black HAIII 16650 LED Flashlight

Some 10 years ago the Quark was the first commercially produced "high output" LED flashlight on the market and it ushered in the era of modern EDC (Every Day Carry) flashlight. The MKIII continues the legacy of innovation that put the Foursevens brand (and founder David Chow) on the map in the world of EDC gear. The design foundation remains the same with the following refinements:

• Industry-leading LED: The Nichia 319A 5000K 80+ CRI LED strikes the perfect balance between beam quality and output.
• Configurable interface: 6 convenient program presets (configurations) allow you to choose your favorite, at any time. The configurable user interface is being standardized across the entire Foursevens line for continunity.
• Burst mode: Using a very fast double press, burst mode (100%) output is directly accessible from any previous level with memory to the last saved mode.
• More beef: A slight increase in the diameter of the entire light improves mechanical reliability and impact resistance. Durability + Reliability = Longevity.
• Pocket Clip: The new clip is made from thicker material, provides easier pocketing, and improved grip (from the clip not the body texture).
• Tailstand cap: Included is the all new snap-on Quark Tailstand Cap for those who prefer a recessed button and a light that can tailstand.
• Hybrid Memory: A blend of memory and no-memory, the hybrid configuration saves the last mode used but reverts to the first mode in the sequence when shifting out of a saved mode.
• Solid Copper (Direct Thermal) MCPCB: The LED is mounted to a solid copper PCB to provide superior thermal performance and maximum output.
• DIY Friendly: Honoring the tradition of individual makers and modders working at home on their kitchen tables components are not glued or thread locked, so they can be disassembled with minimal effort avoiding damage to the light.

The QK16L MKIII powered by one Rechargeable Li-Ion 16650* battery has a black type three hard anodized (HAIII) aluminum construction and carries via a robust stainless steel pocket clip.

Brand new direct from FourSevens.

Operation:

• Make sure that the battery is inserted with the positive side (+) toward the head.
• Press for momentary on or click for continuous.
• A quick off/on cycle changes modes
• Two very quick off/on cycles activates burst mode
• Enter configuration mode with 10 on/off cycles in less than 3 seconds. The light will begin to blink a number of times corresponding to the selected configuration. I.E. Config. 3: 3 blinks, pause, 3 blinks. If there is no input for 5 seconds the light will exit configuration mode.
• Turn the light off for 5 seconds to save the current configuration to memory

*Caution: The QUARK QK16L MKIII will accept 2 x CR123 or 2 x RCR123 batteries. However, it is STRONGLY ADVISED AGAINST USE. Catastrophic failure can occur when one of the two cells is not functioning correctly, causing thermal runaway in the other cell. There is a significant risk of fire and/or explosion when using two cells.
