Nitecore E4K Rechargeable LED Flashlight

Five Outputs from 2 to 4400 Lumens

Four High-Output Cree XP-L2 V6 LEDs

SOS, Beacon & Strobe Modes

Push-Button Switch with Output Memory

As powerful as any primary light and as small as any backup light, the Nitecore E4K Rechargeable LED Flashlight packs more lumens and more output options than most full-size duty lights�ensuring you'll reach for it time and again whether you're on duty, on the job, or on the trail.

Its four Cree XP-L2 V6 LEDs are driven by a high-capacity 21700 Li-ion battery with outputs ranging from an ultra-low 2 lumens for doing tasks like reading without disturbing your bunk mates or checking IDs up to a darkness-piercing 4400 lumens for searches and to clear rooms safely. Three intermediate outputs allow you to select the perfect output for any situation you might come across. In addition to the five output intensities, you also have three specialty modes: An SOS distress signal, a location beacon, and a disorienting strobe. You further have the option for instant access to the turbo mode or the strobe mode depending on your situation or use. All modes and outputs are accessed from a single push button located on the handle with an intuitive interface.

To hold up to daily use, the body is CNC machined as a single uni-body to limit parts, reduce weight, and better dissipate heat. The housing is further treated with a hard-anodized finish that resists scratches. O-rings seal the interior to an IP68 rating, making it dustproof and waterproof to a depth of almost 7 feet, and it is also impact rated to handle drops of over 3 feet. Its compact and lightweight design brings it in at under 5 inches long and under 3 ounces in weight, so you can carry it all day and night and you'll barely notice that it's there. Nitecore includes a holster and a reversible clip to give you multiple carrying options, as well as a battery cartridge that lets you use two of the more common CR123A batteries if you get stuck without the ability to recharge the included 21700 battery.

Performance

• Ultra-low 2-lumen output is ideal for reading without disturbing others
• Low 50 lumens will light a tent, closet, or car trunk for finding gear and checking what you have
• Medium 320-lumen output lights rooms, truck beds, bed caps, and other larger areas for navigating and moving freely around
• High 1050 lumens is ideal for hiking and navigating safely in total darkness
• Darkness-piercing 4400 turbo mode outputs massive amounts of light that illuminates all nooks and crannies for safe searching and clearing
• Four high-output Cree XP-L2 V6 LEDs work together to produce the impressive 4400-lumen max output
• Deep smooth reflector combines the output from all four LEDs into a single beam
• SOS mode: Automatically cycles through the Morse Code distress signal to alert searchers if you are incapacitated
• Beacon mode: Pulses a flash of light at regular intervals to show your position
• Strobe mode: Bright random frequency strobe can be used to disorient a possible threat

Switching

• Type: Push button
• Location: Handle
• Constant-on activation only
• Large textured button cover is easy to find and use, even in cold and wet weather or while wearing gloves
• Last mode memory returns light to the previous output level when it is turned on again�only applies to standard outputs, not to strobe/SOS/beacon
• Instant access to ultra-low output
• Two "User Mode" options: Default "Daily" mode provides instant access to turbo mode; "Tactical" mode gives instant access to strobe
• Simple and intuitive user interface with single switch

Construction
