 EQUIPPED TO SURVIVE (tm) - LED Flashlight Reviews
Many of the water resistant lights function even though they were flooded inside and drying them out after getting wet is all that is needed to maintain their usefulness.  Failing to do so results in a rusty mess that sooner or later quits functioning.
We drop tested the flashlights four times from six feet onto concrete with not a single LED failure and little in the way of any other visible damage to the body of the lights themselves.  That's an impressive showing.
Also, in normal use, where flashlights are generally used intermittently, battery life may be longer because batteries are at their worst when current draw is continuous.

 LED flashlight - Coleman, Coghlan's
The LED Flashlight is a technological improvement of a regular flashlight.
Unlike regular flashlights which use incandescent bulbs that produce a yellowish light and waste most of their energy by throwing off heat, an LED flashlight uses LED bulbs that generate a pure white light, last up to 100,000 hours so you never have to worry about replacing bulbs, and run on 1/10th the energy.
That means with regular flashlights you have to buy 10 times more batteries in the same time frame that you would would buy 1 set of batteries for an LED Flashlight.
