I received my Arc4+ 2nd monday and from monday it has not been more than 30 cm. distant from me , never !
It isn't the brightest little led flashlight that i own but if i had to choose to take only one flashlight it will be the winner . It is my new EDC light and only the Arc5 will replace it /ubbthreads/images/graemlins/buttrock.gif.

As all the owners of an Arc 2nd , i had to investigate why it is a 2nd.The look is just perfect , all the menus and the software options works OK, the beam is bright and white , ( only if i compare it head-to-head with a R3J or with one of my Arc-Lux III T it isn't as white as ...).
It is a little brighter than my Firefly+MM_R2H and a little less bright than my CNC-123+MM_LuxIII_T , looking at the "Runtime-Brightness test of This_is_Nascar" ( i also have a ArcLS Lux3 Fraen @740mA to compare with ) my Arc4+ 2nd seems as bright as the Arc4+ tested by TIN.
It is visible brighter than my ArcLS Q3J @400mA ( that is visible brighter than a LSHP ) but is 25-30% less bright than my ArcLS Lux3 T Fraen @740mA but this only with a new battery (beware the modded ArcLS has a much shorter runtime !!!! )

So i measured the current draw , can someone tell me if they are normal ? They seems ok to me.

3Volt Level 1 --- 820 mA -- 2.46 Watt
4Volt Level 1 --- 640 mA -- 2.56 Watt
5Volt Level 1 --- 520 mA -- 2.6 Watt
6Volt Level 1 --- 440 mA -- 2.64 Watt

now all the levels at 3 Volt :

1 --- 820 mA
2 --- 580 mA
3 --- 410 mA
4 --- 290 mA
5 --- 200 mA
6 --- 140 mA
7 --- 100 mA
8 --- 60 mA
9 --- 40 mA
10--- 28 mA
11--- 19 mA
12--- 13 mA
13--- 9 mA
14--- 6.8 mA
15--- 5 mA
16--- 4.2 mA


At the end i have to say that this is a "must have light" , if you like small led flashlight and if you are thinking of invest 80-100$ , do yourself a favor buy an Arc4+ 2nd, if you can spend the full 180$ you will be even more happy with an ARC4+ first ( but i don't know why /ubbthreads/images/graemlins/grin.gif).

Ciao.

I can't comment on the current draw, but I will add a big DITTO to all the other stuff!!! I have had my Arc4+ second for almost a month now, and I can also admit that it's NEVER been very far from my side! Well worth the money!!! Enjoy!

Those look good to me. I've had seconds that draw nearly 2A!
They sure are bright though. /ubbthreads/images/graemlins/cool.gif

I just want to know from some owner of a Arc4+ first , when the Arc4+ become less bright than a LSHP , mine at level 1 and 2 is brighter and at level 3 is less brighter.

And yours ???

Mine is still as bright as my lshp at level 4. But this is not meaningful since the lshp have not a calibrated brightness: it would actually be better to use the arc4+'s calibrated brightness levels to evaluate the lshp's brightness :).

I have both an Arc4+ first, and LSHP first; my feeling has always been that level 4 on the arc4+ is equivalent to my LSHP.
