Excellent article, Doug. Kudos for all the hard work you must have done.<br><br>Personally, I carry a PrincetonTec Blast keyringed to three Photon II's (white, red, and turquiose) on my person at all times. They are invaluable. I also have a AAA Mini-MagLite in my small bag, a AA Mini-MagLite in my briefcase, and a PrincetonTec Tec 20 in my jacket pocket.<br><br>In addition to the LEDs you reviewed, another LED about which I have heard good things is the Turtlelite, available in two versions, from LEDCORP (http://www.ledcorp.com/), both of which are reviewed on Craig Johnson's web site.<br><br>Take care,<br><br>Craig<br><br>
