The "SP" edition of the EX10 is a special edition that features "hidden" SOS and Strobe modes and has a digital safety lock-out function.
Please note that the lumen specs below are for the R2 version. The Q3 version is a warm white, closer to what you would see with an incandescent light, and is a bit lower in overall output.
Choosing Constant Output
To choose your level of constant output, first turn on the light by tightening the head or (if the head is already tightened) by pressing the tailcap once. Then, press and continue to hold the tailcap and the EX10 SP will cycle through low, medium, and high levels. Release the button to save the level you want.
Choosing SOS / Strobe
To choose the "hidden" SOS or Strobe modes, first turn on the light. To access SOS, quickly double-press the tailcap (do not hold it down). To access Strobe, double-press the tailcap and continue to hold down the second press. SOS and Strobe modes are not "memorized," so the light will always turn on to whatever constant output you have saved.
Digital Safety Lock-Out
To lock-out the EX10 SP so that it won't accidentally activate from a tailcap press, first turn off the light and then press and hold the tailcap for more than one second. The light will flash once to indicate that it is now in lock-out mode. To cancel lock-out, simply triple-press the tailcap rapidly.
Summary of specifications for EX10 and D10
- Unique electronic-controlled extremely reliable switch design.
- 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
- 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!
- Extremely compact size and lightweight suitable for Every Day Carry (EDC).
- As with all NiteCore products, they use tough, imported 7075
- 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 XP-E 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.
- Uses CR123A's as well as protected lithium-ion RCR123A's!
- Stainless steel retaining ring in bezel.
