EX10 - LNIB - $54 shipped to a USA address
* Unique electronic-controlled extremely reliable switch design.
* Unique Infinitely Variable Digitally-controlled Brightness System.
(100 levels of output!)
* Piston Drive (PD) design makes the light more compact than lights with traditional clicky switches.
* Switch reliability is greatly increased over traditional switches.
* Electronically controlled switching - no spark generated from the piston contact since the microprocessor switches on the light AFTER the piston makes contact. This eliminates the risk of explosion in a flammable environment!
* Electric current passes through the piston on the INSIDE of the light. No current is passed through the outside shell, which is hard-coat anodized.
* When the light is off, the microprocessor draws very, very little power - between 0.1-0.4ma (0.2ma typical). For example, one 2000mah cell would last about 416 days!
* Instant access minimum & maximum brightness - very simple user interface.
* Extremely compact size and lightweight suitable for Every Day Carry (EDC).
* As with all NiteCore products, they use tough, imported 7075
military-grade aluminum!
* Mil-Spec Type III Hard Anodized finish - no bare aluminum exposed, making it more durable.
* Aggressive knurling over most of the surface - maximizes grip.
* Resistant to impact from dropping in accordance with US MIL-STD-810F.
* Waterproof to IPX-8 standard.
* Broad-voltage fully regulated circuit, compatible with standard primary batteries as well as protected li-ion cells
* Uses a highly efficient Cree XR-E Q5 WC LED lamp.
* 130 lumens at maximum output.
* Extended runtime on low (3-5 lumens)
* Metal reflector with optical grade coating.
* Impact-resistant optical lens with anti-reflective coating on both sides
* Tactical lanyards braided with military-grade 550 parachute-cord.
* Able to tail-stand to act as a candle.
* Uses CR123A's as well as protected lithium-ion RCR123A's!
* Stainless steel retaining ring in bezel.
