Hank, is it possible to get a V2 Nanjg driver instead of the V1?
This one really ticks all the boxes of a great edc!
small with good styling
square threads
HAIII
3 mode no strobe
stainless steel bezel
fits most batteries
neutral tint available
Now I just need to know if there’s visible PWM and im sold!
if I didn’t have the roche f12 I would probably buy it…really nice light…
True. I don’t see much difference from Roche f12. And F12 does not have visible PWM for sure. But F12 has a higher low (around 50lm I guess). This new one has a green clickie, which does not go with the golden body IMO.
Hey, nice host, Hank 
Have a question though: what’s the difference between those drivers? Nanjg 101-AK-A1 is just a one sided Nanjg 105C and less 7135 chips? Everything else is the same?
You have this beauty with clip 
Don’t know what driver does it have though 
Did I missed something? 
v2 Nanjg?
No PWM from Nanjg drivers AFAIK :bigsmile:
maybe means the 3+ Amp driver
I guess he's talking about the KD V2: http://kaidomain.com/product/details.S020064
actually this one. The v2 nanjgs use 380ma chips and have nicer mode spacing and come in 4, 6 & 8 chip versions. KD isn’t the only place that sells them though they were the first.
What kind of warranty do these lights carry BTW? Nice light! Length is fine, but a little bit fat for me as EDC.

what does PWM mean? thats a sweet light. it intl-outdoors legit?
PWM = Pulse width modulation
Everything I have heard about them is on the UP and UP!! Just placed my first order with them 2 days ago.
ok what does Pulse Width Modulation mean? does it mean how fast the light flashes?
PWM
Pulse Width Modulation. A technique of varying the brightness of a LED by flashing it on and off very quickly, making it appear to the eye that the LED is dimmer. Good PWM is at such a high rate that you can’t notice it. But if you wave your hand in front of the light and get a strobe effect, the PWM is getting too low. Some use current regulation which makes the light dimmer without PWM and is also more efficient.
Here is a link that you might find useful that has some of the words and stuff related to flashlight stuff
Impulsively ordered one. Will report back. I will be happy if can get one work day off mid mode and 3100 18650, and throw is good.
So what will be the real-world difference in performance with the new XP-G2 LED?
Hopefully I can let you know shortly after my cutter order arrives. I have a few lights picked out for the swap...
Nice looking light! I so wish there would be XM-L’s U2 bin in 2B tint available
Pretty sure it’s just more efficient. http://www.cree.com/news-and-events/cree-news/press-releases/2012/july/xpg2-intro
20% that is…
Here’s an excerpt:
Built on the revolutionary SC³ Technology Platform, the XP-G2 LEDs combine high light output, reliability and efficacy to deliver up to 151 lumens per watt at 350 mA, 85°C or 165 lumens per watt at 350mA, 25°C in cool white (both at 6000K). In warm white (3000K), the XP-G2 LED delivers up to 133 lumens per watt at 350 mA, 85°C or 145 lumens per watt at 350mA, 25°C. The SC³ Technology Platform leverages Cree’s advanced silicon carbide technology, features advancements in LED chip architecture and phosphor and showcases a new package design to deliver the most advanced lighting- class LED components in the industry.
So it’s just as efficient as an Xml basically
The problem with PWM is that it drives to led to HI then Off. On High, the led is less efficient than at a lower current level. Just because it is off for a small period of time does not mean the average brightness, as seen by user, is not lowered. I believe the bottom line in the CPF forum was that PWM is NOT the most efficient approach, because of this principle. I am wondering why this technology persists in drivers?
it’s cheaper than current control…
