Surefire LED E1L Outdoorsman. Fits in pocket. Uses 1- CR123A battery. Last over 8 hours. Expensive but worth it. This is no doubt the best small flashlight for every day use. Can buy 20 batteries on-line for less than $25.00
Just got the new Surefire P2X Fury flashlight. I've got stream light, Fenix and Surefire collection of lights and have to say that Surefire has been the best to deal with warranty wise as well as quality. The flashlight is a very important tool in our trade and is quite a hassle when it fails to operate properly so I will only buy the highest quality brands. The P2X Fury is 500 lumens on high stage! It only last 1.5 hours on high stage but 46 hour on low stage at 15 lumens. So far i love it. I may try rechargeable versions of their lights but for now it's just easier to use disposable. I keep many boxes of batteries because all brands use the cr123a battery and I don't trust using some cheap Chinese knock offs to save a few bucks. I usually change batteries every 1-2 weeks. They are equivalent to aa lithium in the pricing cataegory. http://www.surefire.com/featured-pro...al-output.html
After 20 + year's I've tried them all. My newest favorite is "The Larry Light"
Real bright, not heavy at all, takes regular batteries, has a magnet, clip that's moveable, and it's under 12 bucks.
I tried head lights but they mess up my hair
