QUARK QK16L MKIII
FLASHLIGHT
"CLICKY" INTERFACE AND
OPERATION
QUARK lights have a "dicky" user
interface
clicking or pressing the tail cap switch to
turn the light on or off.
Best practice is to replace/recharge
the battery before it is completely
empty. Modern rechargeable batteries
will last longer if you recharge them
before they are fully depleted.
the light is controlled by
Please Note: Configuration 2 does not
have Burst mode because the default
output is already 100%.
A light "press" on the switch activates
the light in momentary mode. A full
'click" latches the light on or off.
MODES
Low (Moonlight) = 0.8 Lumens
Medium = 70 Lumens
High = 300 Lumens
Max = 650 Lumens
Burst = 650 Lumens
SOS = International Distress Signal
Strobe = 650 Lumens @20Hz
Beacon = 2 blinks every 5 seconds
If the battery is fully depleted you may
trip the low voltage protection circuit,
disabling the battery. In most cases the
Flex charger can reactivate it, but fully
depleting the battery should be avoided.
MODES AND MEMORY
When the light is on, change modes with
a quick off/on cycle (less than 1 second).
BATTERY INSTALLATION
The battery should be installed with the
(+) terminal facing the head. NEVER
install batteries backwards.
Mode memory is a "hybrid" type that
remembers the last setting, but reverts
to mode 1 of the current configuration
on the next mode change.
BURST MODE (100% OUTPUT)
Typically 100% output is not needed.
Burst mode is a battery saving feature.
If you do need full output, activate burst
mode with two very quick cycles (<.25
seconds). Burst mode has no memory,
so the light will return to the last saved
mode.
BATTERY COMPATIBILITY
The best battery to use is the
Foursevens 16650 Li-Ion rechargeable
provided with your flashlight. To

USER PROGRAMMING
The QUARK has six user selectable
configurations. Enter the configuration
menu by cycling the light 10 times in
less than 3 seconds. Use a momentary
"press" (not a "click") when entering
configuration mode. The light blinks a
number of times equal to the configura
tion number selected. Cycling the
button one time changes to the next
configuration. Leaving the light off for 5
seconds saves the current configuration
to memory.
The QUARK QK16L MKIII will accept
2xCR123 or 2xRCR123 batteries.
However, we STRONGLY ADVISE
AGAINST THEIR USE. Catastrophic
failure can occur when one of the two

The light maintains Burst Mode for 30
seconds and then ramps down to High
mode over the next 30 seconds to
prevent over heating.
