Thanks! I got my Led Lenser M7 was doing some research of what batteries should I use. When alkaline batteries are draining, the voltage gets lower and lower. With NiMH batteries the voltage stays pretty much the same and it suddenly goes away when the battery has no power anymore.
 
So the M7 has a circuit (or something like that) that keeps the voltage the same so you get a constant brightness no matter how much you (alkaline) battery is used. Will that circuit still work with NiMH, since NiMH and Alkalines act differently when being drained.

Virtually every good modern led flashlight uses pretty sophisticated voltage/current regulation circuits these days.  I am not aware of a quality modern AA flashlight that will not work with NiMH cells.  Just remember, when you're out of juice, you're out of juice, and yes, that comes upon you more by surprise with rechargeables than with primaries.

Thanks a lot for kwkarth and all of your guys help! 
I haven't seen much forums with so much helpful people, you can just ask about any gadget and there will be an expert on it here on headfi!

Thought I'd post a comparison between the joke of a flashlight and my TK35.  The joke being a 3 cell Maglite.

Yep, an incan 3D Maglite only outputs 45 lumens. Surefire's P60 lamp had a bit more voltage to work with and was a bit better at 60 lumens. These days, I get that sort of performance from a dinky 1x AAA Preon. It's amazing how much LEDs have improved flashlights in such a short amount of time.

Got my Led Lenser M7! Very bright, and feels durable.

No kidding!  It is truly amazing.  I think my Surefire C3 hasn't been fired up for two or more years.  I get well over twice the lumens (almost 3x) from less than half the power in my Olight Triton, and it (the Triton) has been old news for over a year already.

Yeah the M30 is still a good light.  I have a not so good comparison between the M30 and TK35, I'll post it later.  The TK35 totally outclasses it in throw and spot brightness, even though the pictures don't show it too well.  Shining them inside doesn't give you a huge difference, but once you take them both outside it's a different story.

I can believe it!  I see the same thing when I compare throw between the M30 and my TK40.  My TK40 seems to throw about 30% farther outside, but inside it's difficult to see substantial differences in brightness.  I only use the M30 with 3 cells, not 4 and I suspect it would be somewhat brighter with 4 cells.
 
Your TK35 uses the very latest LEDs and I love the form factor and user interface.  It's on my list!!

Indeed.

Tried my Led Lenser P7 with lithium AAA batteries, there wasn't any noticeable difference on the output. Let's hope it lasts longer. EDIT: Actually the difference is big, you can't really see it during the day, but at night lithium batteries does make the P7 much brighter. I am kind of worried that it gets hot, so for long hikes I still use alkalines.

wow , me and my $5 Led light!

 

[Edwood]

Yeah, some people are happy with stock iBud earphones too.

 

[yliu]

I always thought my Led Lenser P7 are great and durable, until today. It fell out of my hands while I was lifting them above my head, around 2m high to a concrete ground... it broke. It only lights up when I tap and hold the button.

 

[Edwood]

I dropped my modified Surefire L4 a few times, from waist, and chest height onto concrete.  Only a few nicks and marks on the bezel.  Still works perfectly.

 

[immtbiker]

Yeah, both my Fenix flashlights (large and small) have taken some serious suicidal drops onto the floor and concrete with no "ability to light" problems occurring. Worth every penny.

What about "1 ipod bud"...the other being shared in their friends ear. 
 
Now that's true audiophile quality, especially if it's a 128kbps file. Life doesn't get much better than that, no?!
