FSQTLCAE: Quark CR123A Tactical No Clip Gen 2 Cool White LED
The second generation XP-G LED lights are 20% brighter on all output levels while maintaining the same runtimes as previous models.

The Quark series offers a staggering array of options, accessories and interchangeability. With a wide range of LED, battery and clip choices, you get the features you want without compromise. Available in a Pro multi-mode interface or a Tactical interface with programmable primary and secondary outputs, these lights can be used in a wide variety of settings and applications. Waterproof and constructed with aircraft-grade aluminum and impact-resistant lenses, Quark lights are tough enough to meet any challenge.

Note: The Quark Tactical QTLC does not have a clip.

The Quark Tactical subseries operates with a significantly different User Interface than the regular Quarks. This UI allows the user to program both primary and secondary outputs.


Operating your Quark Tactical is simple. Insert the battery with the positive side (+) towards the head. Make sure the head and tailcap are tightened, then depress the tailcap button fully so that it "clicks" and the light turns on. You can also press the tailcap lightly (you don't have to "click" it on) to activate the light momentarily. This is known as the momentary-on feature.

The Quark Tactical can memorize any two modes of output, from its eight total modes, to be instantly available. These two memorized modes are accessed by either tightening or loosening the head (for example, tight can be Max, and loose can be Low).

Programming Modes:

To have your Quark Tactical memorize a different mode, turn it on and loosen the head by a half-turn. Then, tighten the head at least four times rapidly (twisting it tight, then loose, then tight, etc., four times). After the fourth time, leave the head tight or loose depending which position you want to program.

After three seconds, the light will flash, signaling it is ready to be programmed. Cycle through the eight available modes by clicking the tailcap off and on. The mode sequence is as follows:

Moonlight -> Low -> Medium -> High -> Max -> SOS -> Strobe -> Beacon

Once you find your desired mode, leave that mode on for ten seconds and the light will flash again, confirming that the mode has been memorized. To cancel programming before it flashes, turn the light off for three seconds.
