Nitecore have introduced the compact EC21 which is one of their latest additions to the Explorer series of flashlights. The EC21 measures just 108mm in length and is constructed from a CNC machined aircraft grade aluminum alloy. The flashlight features a crenulated bezel and an HAIII military grade anodized finish. The EC21 also features an anti-rolling frontal design, a diamond-shaped knurling on the lower half of the flashlight, grooves for a two way detachable clip and a lanyard hole. A metal clip, lanyard and holster are included in the Nitecore EC21 flashlight pack.
The EC21 contains a Cree XP-G2 (R5) LED for white light illumination and a secondary red LED for constant illumination to preserve night vision and flashing illumination to serve as a signal light. The flashlight can be powered by one rechargeable 18650 Li-ion battery or two CR123 batteries.The EC21 produces a maximum output of 460 lumens, a beam of 194 meters and eight light modes: Turbo 460 Lumens 1Hr 45Min One 18650 Battery – 1Hr 15Min Two CR123 Batteries; High 210 Lumens 4Hr 45Min One 18650 Battery – 4Hr 15Min Two CR123 Batteries; Mid 100 Lumens 12Hr One 18650 Battery – 10Hr Two CR123 Batteries; Low 20 Lumens 50Hr One 18650 Battery – 48Hr Two CR123 Batteries; Lower 1 Lumen 430Hr One 18650 Battery – 280Hr Two CR123 Batteries; Strobe; SOS; Location Beacon.
The Nitecore EC21 is operated by a dual-switch system located at the side of the head. The lower button controls the on/off operation of the flashlight and the upper button facilitates access to the light modes. With the light switched off, press and hold the on/off button for more than one second to access ultra-low mode (1 lumen). With the light switched off, press and hold the mode button for more than one second to access turbo mode (460 lumens). When in turbo mode, the EC21 will adjust output luminance automatically within 20 minutes of use to prevent overheating. With the light switched off, press the mode button to enter red light mode. In this mode, the secondary red LED will illuminate steadily. When in red light mode, press and hold the mode button for more than one second to enter the signal light mode. In this mode, the secondary red LED will flash to serve as a signal light. Press any button to exit the red light /signal light mode.
The EC21 features Nitecore’s “Precision Digital Optics Technology” (PDOT) which provides for extreme reflector performance. The flashlight also features reverse polarity protection which prevents damage from incorrectly inserted batteries and two lock-out modes to prevent accidental activation. Pressing and holding the on/off and modes switches for over one second sends the flashlight into lockout mode. Additionally, loosening the tailcap of the EC21 would cut off power entirely which is recommended for extended periods of non-use. The Nitecore EC21 is a neat flashlight that can be carried with you at all times and can be easily manipulated to satisfy your illumination requirements.
