/ Interfaces and Modes

PRO INTERFACE
The interface used in our Quark Pro lights. Lights with the pro interface have quick and easy access to the Max and Moonlight modes by tightening or loosening the head of the light. The other modes can be accessed by momentarily depressing the tailcap button while the light is on. The mode sequence is determined by whether the head is tightened or loosened. 

TACTICAL INTERFACE
The interface used in our Quark Tactical and Quark Turbo lights. Lights with the tactical interface have two memorized output modes accessed by either tightening or loosening the head of the light. These two modes can be reprogrammed to fit your needs.

MOONLIGHT MODE
A hyper-efficient low-light mode. At just 0.2 lumens, it provides just enough close light without compromising night vision. Perfect for map reading in darkness. This feature allows a light to run continuously for weeks on just one set of batteries.

STROBE MODE
High-output strobe mode is both disorienting at close range and attention-getting at long range. Effective for both personal defense and emergency signaling.

SOS MODE

A Morse code–style flashing that spells out S-O-S for signaling distress.

BEACON MODE
A signal mode that is highly visible and will run for a very long time. It ramps the brightness up and down once every 10 seconds, creating a bright visual signal that conserves battery life.
