let me make a constructive suggestion.
this is only one man's point of view.
I have owned a variety of flashlights in my time .. including the good old fashioned Maglites (big and small), a variety of LED lights, and one tactical flashlight that was so tough you could probably run a tank over it.
In the end, you just DON'T need a tactical flashlight that is so bright that you can illuminate the planet Mars. It's truly a waste of time, and a big waste of money.
If you get a small handheld flashlight that is dependable, has a few good LED bulbs, and works with standard batteries (esp. AA) - this is absolutely all that you need. You will save yourself a ton of money. Look at the suggestions on this thread, and get a very reliable LED light.
Just my $0.02
