I just have 2 of these: UltraFire 7w 300lm Mini Cree Led Flashlight Torch Adjustable Focus Zoom Light Lamp
[Link: amazon.com]It's basic, cheap and won't roll due to belt clip.
I have my flashlight on my belt at all times.
I'm not in SWAT trying to illuminate a city block.
This light is small and good enough to do anything I need it, be it behind a cabinet, crawl space, dark driveway on my way to the van after dark, etc.
And because it's inexpensive, I won't lose any sleep if I forget it somewhere.
The only annoying thing is that it always goes from LOW, HIGH, BLINK.
BTW, I have purchased one of the $89 super flashlights and found them to be too bright, large and unnecessary since I have my mini.
