In love again?(NEX R2)Update:Maybe not!

[Art]

Hi,
just decided to try my first CR123 light. I was always against this battery type lights (just like I was against 18650 ones..) but decide to give a try.
First I ordered at DX some 16340 but as most of you know , they havent arrived yet :thumbsdow
So , NEX arrived and I just bought a primary CR123 to test it (after 2 days looking at it without light).

Well since I only have a primary I cant yet to some runtime charts (expencive bats) but after talking so bad about this type of lights I felt in love.
Dont really know how the regulatition , the Q5 version was not very good , but the power for the size is amazing :thumbsup:

Will wait for the 16340 to make a proper review (cant find a runtime chart of the R2 version) and find out if the R2 version has a proper regulation "line".

Until then , some pics with the phone since my camera is in my car :thinking:

Really like it lovecpf

BTW, this smile really shows what this lights do to us

Be back with a runtime and lux readings... just make DX deliver the 16340 lol

Regards

Re: In love again?(NEX R2)

the NEX is a really great light. Glad you are happy with it. It has always been my favorite EDC although I am EDC'ing a RA 170 at the moment the NEX is still my favorite.

Lux reading on a Sanyo CR123 is 3500lux.

Not bad since a NDI on 14500 measures less then 2000lux on my reader.

Re: In love again?(NEX R2)

So finally last week I got some 16340 cells , actually I bought 2 AW 750mah.

Just did a runtime test with it and Im not very happy. Comparing to the runtime chart here ( http://www.light-reviews.com/nitecore_extreme/ ) I thought that the R2 version would be better in something , at least runtime... but no , I got exactly the same runtime chart.

Here are the values.. I will make later a chart:

NEX R2 AW 16340 750
time temp lux
0 23,4 4060
5 27,2 3500
10 31,4 3300
15 34,2 3120
20 36,6 3000
25 36,7 2880
30 36,2 2750
35 36,6 2800
35 36,6 0


As always I also fitted a probe at the light when doing the test.

Now testing with Trusfire 880mah cells.

Be right back with results since this lights have very short runtimes... :scowl:

Re: In love again?(NEX R2)

BTW, there is a difference in nearly 500lux when using the AW cells. The Trustfires give more light the the AW ... 4300 vs 4060.

Here is the run with Tursfire 880mah protected (where?) sku 24680 at DX

NEX R2 Trustfire 16340 880
time temp lux
0 24,7 4300
5 30,6 3700
10 36.3 3500
15 39,2 3350
20 40,5 3220
25 41,2 2830
30 40,7 2830
35 39,8 170
40 34,6 20
45 31,4 8

After 45mins it was still coming light out of it and no cut from the cell... so I decided to stop the test because it was looking like the protection was not coming in... and it was not!
Took the cell out and it was at 1.96v !!!

Im recharging that cell but its probably dead.

Tomorrow I will do proper runtime charts.

BTW, temp is temperature measured at lights head.

Well, I guess that's why people advise you to buy AW and avoid Trustfire...

I'm new to li-ions and ordered a few AW, but also a few 900mAh from Batterystation. Ralight sells them with their lights, so I thought they must be good (read : thought, not knew...).

Why buy a protected cell if protection doesn't work? From what I read about dangers concerning li-ion, that cell would immediately be dumped and not recharged. If I had others of the same built, they would join the faulty one.

I guess you are used to li-ion and you know what you do...

I also have a NEX (GDP) and plan to feed it with a li-ion once I have them. Your measures seem quite normal to me, as per a review it should run about 47 minutes to 50%, you got a little less, but I would expect that. Using rechargeables is all about having enough spares!

My Extreme is also one of the lights that I carry and use most often - even though it has quite a ringy beam, it out-throws anything of its size and the rings don't matter outdoors.

Mine works much better on rechargeables than primaries. It is important to remember though that it doesn't have battery protection built into the light itself the way that the RA does. I always use AWs though and top 'em off regularly, and haven't had a problem.

The more efficient LED is being run by the same driver as the normal version, so runtime should be similar.

Buying good quality products means you will have much less chance of something failing, as you can tell from the battery.
