Nitecore 4400 Lumens Compact

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 bunkmates 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

The 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 the 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 a single switch

Integrated USB-C charging port on the battery allows users to plug the included USB charging cable directly into the battery without the need for bulky charging bases/cradles

Digitally regulated output maintains a consistent beam intensity throughout the battery charge

Advanced Temperature Regulation (ATR) system monitors the internal temperature and automatically steps down the output intensity to prevent damage due to excessive heat

Reverse polarity protection prevents damage if the battery is installed backwards

Integrated battery level indicator on the push button

Capable of running on two user-supplied CR123A batteries using the included battery cartridge; outputs and runtimes may be affected
