I don't have much experience with LED lights except the Photon Micro-lights. Today, just after I received a Pilot-3 and Trek-2 from Glow-plug, I saw a "new item" at Wal-mart.
It is a 2-cell AA light sold by Brinkman, about 5 inches long and 1 1/4 inches in diameter, with a reflector and lens for the white LED. The light is activated by a push-button on the tail end. It has a very narrow central beam, which projects surprisingly well, certainly compared to the other lights I just received. My initial impression is that the two 3-cell lights (apparently both made by Tektite?) have wide, diffused light good for walking, but this Brinkman will be good for finding things I drop behind and under furniture, or looking in the garage, etc.
It looks similar to the Pelikan prototype mentioned in an earlier thread. It only cost $11.56. The package describes it as "water and shock resistant" and claims "up to 20 times longer battery life" than standard 2AA flashlights.
I don't know much about it otherwise, but would be interested in hearing opinions from more informed users.
