You need more than 100 hours' runtime? Both D10 and EX10 can do this!!
After testing by CPFer chevrofreak, using regular AA/CR123 battery, D10/EX10 could sustain at Min brightness continuously for about 100/144 hours, D10/EX10 may be the sinlge AA/CR123 light that has the longest runtime of the world till now, and this proves that D10/EX10 can be your most reliable "partner" whenever needed. :) Please refer to the

NiteCore releases OSRAM's Golden Dragon Plus LED light. We use this new light source for all NiteCore models now.
Heat sink design
What are the advantages of OSRAM GDP?
1. Its very beautiful and soft beam pattern.
2. Lower VF vlaue, nominal 3.3V versus the CREE's 3.8V, which improves the efficiency of the circuit in some sort.
3. Higher Color Rendering Index (CRI), 80 versus CREE's 75, which means a more accurate representation of colors.
Here are pictures and beamshots for your reference.

We have three very exciting announcements!
1)NiteCore Tactical Technology and 4Sevens, LLC will be working together for NiteCore light in the future. 4Sevens, LLC is NiteCore Tactical Technology authorized North American distribtor. All NiteCore products will be available for purchase at 4Sevens.Com and for dealers at
NiteCoreUSA.Com.
2) We licensed the PD (Piston Drive) concept from our famous CPF flashlight master McGizmo! And with this as the base,
NiteCore has taken a further step to integrate a microprocessor controlled interface dubbed as the
"Smart PD" System. The Smart PD series is amazingly simple to operate yet packed with intuitive features.

3) The first two "Smart PD" products will be available for purchase in less than two weeks.

Now a little bit about the Smart PD System.
Why Piston Drive?
We think's Don's piston design is just cool and pure genius. It's an
excellent solution for pure momentary applications yet it also serves as a "twisty" light.
The Smart PD system retains these two important features.
There is nothing cooler knowing how the piston works as you pressing the tail and "interacting" with the head of the light.
It also accomplishes two things:
1) It takes the current path out of the casing for the light. Electricity travels through the piston instead of the exterior casing. This is advantageous in certain applications.
2) Secondly, it moves the switching mechanism to the front of the light and increases the "contact area" where the circuit is completed, thus increasing it's reliability.
Why is the increased contact area so important?
It is a little known yet very serious problem with MOST clicky lights is that they are prone to fail due to the design of the clicky switches. (This has found to be the case even in high-end expensive $200+ lights!) This is because these clicky switches were never designed to handle heavy current loads in the first place. They are "signal" switches and not designed to
carry current. Most lights using these switches often take over one amp of current. Each time the clicky is cycled, the contacts build up a little "carbon" and the switch begins to build up resistance and will ultimately fail. It is very obvious when you open up one of these switches and
study the actual tiny contact points. When a switch handles more current than it is designed to take then it is not a matter of "if" but of "when" the switch will fail AND how lucky you are :)
We don't want any part of luck when it comes to your light turning on.
That is usually not a problem with consumer grade flashlights not designed for daily duty. However, in mission critical situations, the last thing you want is a failed switch. The PD design solves this problem.
The Smart PD system actually switches on electronically, so the actual contact between the piston and the head is even more reliable. The higher current is applied microseconds AFTER the piston has made contact.
So whats so special about the "SMART" PD?
The Smart PD System inherits all the basics of Don's PD (except for the two stage output based on the piston pressure).
It's very simple. Twist the head tight, it turns on. Loosen the head, it turns off. You don't even have to touch the piston.
It doesn't get any simpler than that - it's a basic twisty.
While the head is loosened, you depress the piston in the tail and the light comes on. Release it and it turns OFF.
Pure tactical momentary. Beautiful. We can just stop here since this is probably what 90% of what people use to
turn their lights on :)
Ok... So if you want it to operate as if it has a clicky tail - Tighten the head and the light turns ON.
"CLICK" the piston and it turns off. "CLICK" again and it turns on.
(a "CLICK" is defined as a quick push and release of the piston within 0.3 seconds)
It's beautifully simple. The action is quiet compared to traditional clickies.
There is no latching mechanism like in a clicky switch - it's all handled by the microprocessor in the head of the light.
Ready for something more? While the light is on, "PRESS" and hold the piston and it ramps up the brightness to maximum. Now release it and "PRESS" again will ramp it down to minimum. The ramping action stops when you
release the piston. (a "PRESS" is defined as pushing the piston longer than 0.3 seconds)
There are 100 levels of output to choose from - more than ample to suit ANY task.
The Smart PD will remember your last output setting in memory. So if you click off and click back on, it will come on at your last setting. Genius.
Say you want instant access to MINIMUM or MAXIMUM output. It's a piece of cake. While the light is ON, do a "CLICK-CLICK" and it jumps to the MINIMUM. Or a "CLICK-PRESS" and it jumps to MAXIMUM.
Or if you want to get to those extreme outputs while the light is OFF:
"CLICK-CLICK-CLICK" jumps to MINIMUM and
"CLICK-CLICK-PRESS" jumps to MAXIMUM.
Thats it. No hidden mess-with-your-brain-strobo. It's simple and utilitarian.
Here is a video that will run through the whole Smart PD interface.

A Summary of specifications for EX10 and D10:
- Unique electronic-controlled switch - extremely reliable
- Unique Infinitely Variable Digital-controlled Brightness System (100 levels output!)
- PD (Piston Drive) design make the light more compact than light with traditional clicky switches
- Switch reliability is greatly increase 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
annodized.
- 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
- Made from very strong military grade aluminum alloy
- Extremely compact size and light weight suitable for EDC (every day carry)
- 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 - maximizing grip
- Resistance to impact by dropping according to US MIL-STD-810F
- Waterproof to IPX-8 standard
- Broad-voltage fully-regulated circuit, compatible with various kinds of batteries
- Uses a highly efficient Cree XR-E Q5 WC LED (Light Emitting Diode)
- Torch Lumen 130 lumens on maximum setting.
