Nitecore D11

it was ashe18c too, but i couldnt log in, and when i tried to get the password emailed to me in case i typed it in wrong, it said my email was used already, so i just left it alone, until i couldnt take it anymore, and registered under another email, but this time the username worked, but just not that email. I really dont know what happened. Just happy i can log in now.
 
There's no record of a prior registration, so I don't know what has happened. You are registered here and on CPFMP with different email addresses, so the MP one seems to have survived whatever it was that happened here.
 
hmmm.... I wonder if the inclusion of sos/strobe for the D11 is a result of
1) more and more ppl going green so they use this as a bicycle light
2) they've been watching too many films that suggest disco modes can stun attackers ("Kick-***") :grin2:

:thinking:
 
Tomorrow I read in another thread about a terribel parasitic drain, the poster wrote something that a battery was drained within 8 days or so... :sick2:

Well, I remembered putting a fresh 14500 in my D11 three weeks ago and I have only used the light for a few minutes (but on high...). I just checked the cell and it was at 3,80V!

OK, that's not scientific, maybe I used the light more than I remember, but somebody with the right equipment should take some measures as I suspect the drain is not close to zero! 🤢

AardvarkSagus, check the EX11 while you are at it!

I always locked all my EX10 and D10 out, an old tradition I just revived... :sigh:
 
Just received my D11 and was surprised to see when I opened it that the color was black instead of the natural finish I've seen everywhere. Personally I don't care for the black, I've just had too many lights that were black and I'm kind of sick of it.

So, I'm bummed, it may seem trivial, but the look of the light is just as important to me as the performance of it. Anyone else see the black version?
 
Also, I was able to use an AW14500 with no problem. I did notice that the D11 is about 1/16" taller than the D10, so I wonder if that's something they changed in this new batch.

I noticed too that the knurling isn't as deep and aggressive as my D10SP.

I like the beam and output on a 14500 very much. It's a beautiful wall of light.
 
Black? Huh, they're dark grey in all the publicity photos.

Bummer. I really like the dark grey Nitecore lights. The SR3 in black is nice... it suits black - but the Infinity, PD and EX series definately look better in grey.
 
Tried the multimeter today, but I am not really ready to put too much stock in the readings. I'll explain why in a moment.

On a partially used AW 16340 I got 0.7mA parasitic drain when in standby and on a marginally fresh CR123A I got an abysmal 3.3mA.

My trepidation in using these figures as actual veracity is that when I tried testing the max draw from the light, it appeared much dimmer running through the multimeter than it did just running through the light itself. It causes all the figures I was getting to be somewhat suspect.
 
That would be attributable to the internal resistance of your multimeter. It shouldn't have a large impact on your parasitic drain values. What light were you testing when you were using CR123 cells? Obviously not the D11...

[edit]

Ah, sorry I missed Henk Lu's post above... It was the EX11 you were testing.

So, question - are Nitecore using driver circuitry in all their new lights which has abnormally high standby current draw? What's up with that? Are they trying to lower sales?! 🙁

Nope, both these cells were tested on my EX11. This just happened to be the thread where I was asked to chime in. NiteCore hasn't offered me a D(anything) to test yet, but if you want to see my take on that favorite, feel free to let them know. 😉
 
I might just do that... Then again, I might also make it my first ever flashlight review!

Seriously though, I am getting a little concerned about Nitecore at the moment. They're my favourite 'production light' manufacturer at the moment (I'm told that would change tomorrow if a SF E2DL dropped onto the doorstep in the morning) but they REALLY seem to be slipping lately. From the (alleged) use of uneconomical circuitry to not induing clips with the D11 and EX11 as standard, to off-centered emitters. It all seems a far cry from the Nitecore who brought us the original Smart PD lights, EZ, EX and Defender series.

I just received a D11 and personally I think it's great. Yes I would prefer the shortcuts to high and low, but ramping up and down isn't hard. The LED is perfectly centered and the beam is beautiful. Nice white tint and a wall of light. The only thing I'm not happy with is that mine is from the new batch that is black and I really wanted the natural gray color.

I was leery of purchasing a D11 with all the negativity lately, but I'm glad I did. I thought the D10 SP had a great beam, in my opinion, the D11 blows it away.

How do you 'lock out' a piston drive switched NiteCore flashlight????


No mater HOW far I back off on the 'tailcap', I can STILL turn the light on, by pressing the piston switch.

There is a spring in the battery compartment, so isn't the battery STILL subject to drain while the light is shut off?

Or, am I missing something?

My D11 drained a battery in about a week.

When I grab a $60 flashlight, I expect it to work, EVERY TIME!

If you press the button and the light stays on only while it is pressed it means the light is locked out because the circuit is open. Half to one turn is normally enough.

Even if my D11 does not have a particularly high parasitic current I still carry it around locked because it is easy to switch it on inadvertently in a pocket.
 
The Quarks are also a very good option that come with removable/reversible clips, XP-G's and what not. Maybe you'd consider them over the Nitecore? I love my Quark AA-2, but I don't own any Nitecores, so unfortunately I can't speak for them 🙁

Hope this helps,
