Also , the A3 clip can be reversed and clipped to the bill of a hat for a dandy headlamp .
I have a modded solitaire, 1c tint xpg direct drive off of 10440. Pulls 1.7 amps then settles to 1.55 or so. Just a wow light as it gets hot fast. Also have a single rcr123 that pulls 3.4 amps with an xml. Can actually use this for a little while before it gets hot. Has a great beam profile to, more throw than what you would think.
The ITP A3 is one of those lights that everyone should own. Pretty impressive on alkaline & Nimh's but last week I jumped it up to a 10440 and really like it.
Mine is the Stainless "Upgraded" version
My romisen Rc-G2 modded with an xml. draws near 3A on a 14500 :S yikes. but its even brighter than my xeno E03 xml on 14500. a fun short-use pocket rocket.
Sipik 1AA. I loved the f&8k out of that little light...and I sold it last week. 
Currently... This one
8 cm long, pushes out 500-600 lumens... ...for about 15 minutes... if you could keep it on for that long... but you can't... it would caught on fire... ...about 3 mins absolutely max on high... ...but still fun light to have... ...not so much to use... 
I think it would have to be my Mini x 123 too.
HID -
I remember that light - very cool but not something to have in one's pants (pocket) for long while turned on. (the light, I mean)

My Quark Minix123 as well. I use a RCR123 battery, so it overdrives the light about 40%. Cuz more lumens = better! ;-)
Bone stock would be Xeno E03 XM-L, it draws nearly 2.4A with 14500 IMRs. With choice of 3C neutral white tint and warm white 4B. 30 bucks shipped...what's there not to like. (well ok, on dim lowest mode it is still like 100 lumens, but who cares)
Up the ante a bit for length and diameter and it would be Zebralight SC600, full 3 amps discharge to the XM-L.
I just got a SC600 and I have the Xeno and all I can say is WOW....I ask myself why did I wait so long to buy the ZL...
I have had bad luck with the 10440; out of 4 (2 unprotected; 2 protected) the three have gone bad. The only protected still working is in TrustFire F23 Stainless light which I usually run in medium. Trustfire 701 ate all my 10440. Now I am content with DQG and the S1 from Rick_CQN for my AAA lights and I run Eneloop or primary lithium in them.
Hi,
I'm looking to pick up a small light for my wife and am considering the Olight i3, the Tank007-E09 and the Brinyte PD03A.
The Olight seems the obvious choice in that it's an updated iTP A3 which gets recommended many times on here, but the Tank and the Brinyte also seem to get some good shouts, plus they're a little cheaper and some suggest a little brighter. Basically I want the smallest, brightest, reliable light up to $21 shipped (the price of the Olight); which of these three would anyone recommend, or are there others that I'm missing?
I should mention that I'll be running it on NiMH/Eneloop AAAs.
Thanks,
Chris
for the WOW effect
I was impressed by LuminTop Worm II (very floody) and Kaidomain KD V6 with a nice beam
Trustfire Z1, I pretty much use it for everything, I work a lot outside at night, and I've found it to be the most handy light I have, and the smallest!
Klarus mi x6, small light and nice. There are brighter ones, sure, but it is still my preferred key chain light.
Custom TrustFire TR-803 with XM-L U2 1A @ 2.8A
You can have it with your hand closed and don't see the flashlight! I just love it :D
RMSEN RV-107 modded to DD after i bunt out the driver
runs for 30 Min's on a trust-fire 10440 protected doesn't get to hot to hold
and is on par with my ZL H31 on high = 220 lumen for light-output and throw
By FAR my Veleno Designs Quantum D2 (COMPLETELY removed the QTC composite pill, for one mode: high). It takes one 10180 cell (10mm x 18mm), and its body measures 38mm x 13.1mm (1.5” x 0.5” in inches). It lives on a titanium ball chain around my neck constantly, without any split ring or triangle coupler. The balls on my chain measure 3mm, and they just fit through the body’s hole, perfectly for free movement and no rattling/looseness. It’s got a sapphire lens and it’s super bright. It’s stainless steel, so it’ll get hot pretty quick, but I love it.
It’s got two green trits in its bottom. It doesn’t even look like a flashlight worn around my neck (under my shirt), it kind of resembles a bullet.
There's a new reigning champion in this realm. I've replaced that D2 with a G388 from Wuben, of all brands. This particular version is fully Titanium and has a nice UI of two modes, twist farther to get brighter. Lighter weight, better shape with its more curved shape, and it's the best.
