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 R2 LED lamp.
145 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.
