* 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 * 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! * 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. * 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 OSRAM Golden Dragon Plus LED lamp. * 130 lumens at maximum output. * Tactical lanyards braided with military-grade 550 parachute-cord. * Uses CR123A's as well as protected lithium-ion RCR123A's! * Stainless steel retaining ring in bezel. * Dimensions: 77mm x 21.5mm or 3.0in x 0.85in (length x diameter) * Weight: 35g or 1.2oz (without batteries) * Runtimes on CR123A (until 50%) Max: 130 lumens, 110 minutes Min: 3 lumens, 65 hours or 2.7 days! * Runtimes on RCR123A (protected only) Max: 130 lumens, 80 minutes Min: 5 lumens, 60 hours or 2.5 days!

Piston Drive (PD) design makes the light more compact than lights with traditional clicky switches.

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!

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.
