I'm talking about the Fenix E01. It's very durable and has a very good runtime @ a good light output (10 lumens) driven by an AAA battery. The output is flat for 280 mins i.e. great regulation. I ordered mine from dealextreme.com for 15.70$ and haven't received it yet, but according to the many reviews I've read it's very good. Looks like this will be my new keychain light. Manufacturers specs: • Utilizes a Nichia white GS LED with a life of 100,000 hours • Constant brightness: 10 Lumens • Uses one 1.5V AAA ( Alkaline, Ni-MH, Lithium ) battery, inexpensive and widely available • 7.1cm (Length) x 1.4cm (Diameter) • 21-hour working time ( 11-hour sun mode plus 10-hour moon mode) • Made of aircraft grade aluminum • Durable Type III hard anodized finish • 14-gram weight (excluding batteries) • Waterproof to IPX-8 Standard • Reliable twist switch • Capable of standing up securely on a flat surface to serve as a candle Sounds like a bargain to me...
