First Impressions Nitecore EX10 Ti and EX11.2

LED Flashlights – General Info CR123A Flashlights

yes
I believe the drifting only happens above 3.2 volts (as with LiIon)

the EX11.2 works great on CR123… very stable, no weird drifting

here is another reason to prefer CR123 over 16340 in 11.2 drivers
avoiding sudden darkness:

I ran a 16340 down until protection tripped
that happened when the max output had decreased to 110 lumens (max was 225 lumens w an sw30), and the protection in the battery tripped at 3.2 volts, creating sudden darkness…

A CR123 is the right “Octane” fuel for the 11.2 driver

For short use it’s probably not a big deal. But, if you want it to be more stable and still use a rechargable Tenergy makes a 3v cell. I just tried one, works fine but obviously not as bright. I had been using them in my Extreme. Which I am now thinking of selling lol. But that light does have the potential to be a 16340 pocket rocket, a lot more body for cooling. I just don’t like the tactical look. I don’t go out hunting people on weekends.

good call
also less bright on CR123
I dont need more than 100 lumens, on a light I use mostly indoors.

handy as a glovebox light too

72

I’ll take it ! How much for the box of lights :heart_eyes:

73

:beer:

since I started hanging around here
you guys have cost me some cash

74

I don’t know if I want to compliment that collection or build you a box with some sort of separators :smiley:
Nice testing :+1:

75

yes,
Protection is important

I wonder if these plastic bottle preforms could be found in a suitable size

76

Slightly less elegant than I had in mind but still effective :smiley:

77

^ Disturbing ^

:smiley:

You can always get a small bag of the expanding foam with some spacers between the lights. Close up a box and let the foam do its thing! I always save EPP foam, too. That is good stuff for cutting.

Mine came today. Nifty little bugger. Does fine with an Olight protected 16340 - haven’t even bothered popping my spare Vapcell in it. I do wish the shortcuts from off were to low and high, rather than strobe/SOS. Will just have to remember to turn it off in low. Then it’s easy.
I guess the next step is to see about flashing it and/or replacing the MCU.
Oh, and I found a short Jetbeam clip from a dead DDA10.

sadly, not in my experience,
they fit and they work, but
I only recommend primaries, for output stability
and
they are shorter than protected LiIon, so the button is easier to operate.

sometimes the light will not turn off after it is heated up by LiIon use, it goes to low instead
after that when I repeat the attempt to turn off, the light goes into lockout

I spend a lot of time fiddling with the button to get the light to function as requested when I use LiIon

the output is ridiculously unstable when the light warms up

those issues disappear when I do not use LiIon

max on LiIon is over 250 lumens with a 0.1 low,
max on Primaries is about 125 lumens, with a 0.01 low

.

fwiw, about LVP in LiIon cells:
Did a test to run down a protected 16340 in an EX11.2
When output had dropped to 100 lumens, the light went dark.
The protection tripped at 3.2volts

Did a test to run down a CR123 in EX11.2:
When the output had dropped to 50 lumens, the battery was at 2.5volts.
A few minutes later, output dropped to 5 lumens, at which point the battery had dropped to 2.2 volts.

would avoid using unprotected cells, unless you can monitor voltage or brightness, to prevent overdischarge

81

Noted.

I won’t try the unprotected vapcell in it then. The Olight is a pretty weak cell, and protected - I will have to see how it does on longer runs at maximum brightness. If the light isn’t usable at max on LiIon, I will have to figure something else out for it - possibly an entirely new driver… Wouldn’t that be something.

82

My wife caught me getting another.

83

Aaaannd already blew it up. 3 seconds on, died. Some board component is toast. Edit: The seller is sending me a new one so all is well. Probably just the left side of the bathtub curve for electronic failures. Bookmarked the seller. Can’t say I won’t want another. The only thing really holding me back is the possibility of battery selection getting worse for 16340. Maybe that is just being paranoid though. This light is a good balance of output and size and I really love the Piston feel.

84

I forgot to mention: Mine came in with Andrew & Amanda on the return address label, despite being sold by “flashlight_scope_outdoors” on eBay

85

Same here. I bookmarked their site now. Their prices look decent and the shipping to me is pretty quick. Easy to work with also.

Double D10 Models

D10, EX11.2:

Update on my experience using a couple of my Winter Edition EX11.2 for a few days

I stopped using 16340 and am testing with CR123.

I am still finding the light ON at minimum mode, when I thought I had turned it off.

It has happened to me with both CR123 and LiIon.

.

anyone else notice their EX11.2 light on minimum, instead of off?

I have not had that issue with Version 10… both D10 and EX10 seem easier for me to get predictable button response than V11.2 lights.

I attribute the issue to the stiffer battery spring in the 11.2 models. Requires more firm and deliberate pressure when using the switch.

87

YepYep been chasing it for 2 days… like a double tap, from High/Turbo level, drops you back down to Low but with a single Tap as if to turn it off….

88

Maybe the driver thinks you are double tapping instead of a single? Try taking it apart and doing a good cleaning. An intermittent connection might be tricking the uC. If the head is loose enough the wiggling can make it jump to momentary mode and back. When it does jump back it will resume the last brightness. If you pocket carry I would make sure it is not near the point where it can toggle back and forth. But I would start with a good cleaning too since it won’t hurt.
