Prometheus Lights Quark QK2A MKIII Flashlight

Flashlights are simple tools but, something so incredibly game changing when you really need it. Being able to see when it’s dark is a gift, and Prometheus Lights’ Quark MKIII packs enough of a wallop to help you turn night into day with this little gadget. This bad boy may just have one button but, Prometheus did their part to add four different modes to cater to whatever you might need from this torch, including a beacon and SOS mode PLUS, it’s incredibly rugged and can seriously take a beating. We’d never thought we’d be this excited about a flashlight but Prometheus Lights makes it really easy when they’re delivering a device this complete.

FEATURES:

  • 2x GP rechargeable NiMh batteries included!

  • Current Regulation

  • Reverse polarity protection

  • Nichia 319A (5000K / 80+ CRI)

  • Water Resistance = IPX8

NEW USER INTERFACE:

All Quarks feature a new interface with six selectable configuration modes so you can customize your Quark specifically to your needs.

  • Output in programming mode = 15% (medium)

  • Bump Protection = <60ms off time = no mode change

  • Enter configuration menu = 10 cycles within 3 seconds.

  • Mode change interval: .5 seconds

  • Memory set (off) time = .5 seconds

  • Memory function = revert to mode 1

  • Burst Mode Memory = no memory

  • Burst mode behavior = 30 seconds burst (100% output), ramp to high mode (60%) over next 30 seconds.

What’s up with burst mode? : This feature is ported over from the flagship Prometheus Alpha Flashlights. It allows you to access maximum output at any time without scrolling through other modes. This also allows you to have maximum output when you need it, but conserve battery by using the standard high mode (60% output) for normal use.

Burst mode is activated with two very fast off/on cycles (.2 second spacing) and does not have mode memory. Burst is active for 30 seconds and then ramps down to high mode over the following 30 seconds. This is to prevent the light from overheating and damaging the LED, electronics, or battery wrapper.  

CONFIGURATIONS

All Quarks are initially set to Configuration 3 with Medium/High/Burst. They can be reconfigured as often as you’d like.

Here are the possible configurations:

  • Config. 1: High – (Burst 100%)

  • Config. 2: Max (100%) – Strobe

  • Config. 3: Medium – High – (Burst)

  • Config. 4: Low – Medium – High – (Burst)

  • Config. 5: High – Medium – Low – (Burst)

  • Config. 6: Low – Med – High – Strobe – SOS – Beacon – (Burst)

OPERATION

  • Operating your Quark is simple. Make sure that the battery is inserted with the positive side (+) toward the head.

  • To turn it on press or click the tailcap button. A press allows momentary activation of the light.

  • 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. For example if you are in 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
