Summary of specifications for EX10 and D10

• 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 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.

The D10:

• Uses common AA's as well as protected lithium-ion R14500's!
• Dimensions: 89mm x 19mm or 3.5in x 0.75in (length x diameter)
• Weight: 40g or 1.4oz (without batteries)
• Runtimes on one AA
  Max: 145 lumens, 50 minutes
  Min: 3 lumens, 45 hours or 1.9 days!
• Runtimes on one R14500 (protected only)
  Max: 145 lumens, 80 minutes
  Min: 5 lumens, 60 hours or 2.5 days!
