Why spend your hard earned money on a good light, get a GREAT light!
Heck, your the one who has to see with the darn thing.

Here's what I've been using from Surefire:

L2 outdoorsmen; awsome for a pocket sized light that lives in the Jeep console and you can hold in your teeth.
Also clips to the bill of your hat. It takes 2 CR123 lithium batteries that last about 9 months with regular use.

U2; cool, it has up down power settings but I don't like the adjustment method and you can't hold it in your teeth.
Sold it.Also 2 CR123.

For flat out blinding everything with eyeballs within a square mile the M4 Devastator is the weapon of choice.
4 CR123's with 2 different bulbs for brightness.
Crenlated bezel for opening eyebrows like Tyson.
Chuck Norris has this light.

I've had and broken dozens of flashlights. There's a veritable flashlight graveyard in the bottom drawer of my workbench. I could have bought 10 Surefires with all the money I spent on chaep lights and batteries over the years.

Here's what I've found with some common brands:

Pelican makes durable plastic lights.Lens scratch easily.
Maglight makes night sticks with a xenon bulb that breaks every time you drop it or low output led.
Ultrafire makes cheap copys of Surefires lights that get hot and eat CR123's after a few hours. Blue or purple light.
Black Diamonds have poor switches.
Petzels are ok but prone to corrosion at the battery terminals.
Innova lights are good quality but I have yet to see one thats not blue light. I prefer white light personally.
Gerber lights are kind of fun. Green, red, blue, UV leds and such but I wouldn't rely on one in a cave.

Yeah Surefires are expensive but so it a good hammer.

The 2 cell SF lights are getting much cheaper, $40 range. Well worth it in my opinion.
