I would avoid the Maglite Solitare. It is dim and runtime is a bit iffy. A much better light (already mentioned here) is the Arc AAA light:<br><br>http://www.brightguy.com/detail.tpl?cart=10334628042680&sku=ARC3AW<br><br>Review:<br>http://ledmuseum.home.att.net/arclight.htm<br><br>The Arc AAA is about the same size as the Maglite Solitare, also uses a single AAA battery, but is waterproof, more rugged and uses a bright white LED.

The upside of this light is that it has a very long runtime (~25hrs):<br><br>http://www.brightguy.com/detail.tpl?cart=10334628042680&sku=CMGULTWB<br><br>Review:<br>http://ledmuseum.home.att.net/infultra.htm<br><br>While the Photon II is light, bright and has a good shelf life, the inability to handle water seems a drawback. Battery changes are a bit problematic as well. One thought might be to lightly vacumm pack the light and then you would have a waterproof version of the Photon II - just use it through the shrinkwrap! Another issue might be accidental activiation.<br><br>The Photon III has been reported to have some reliability problems but it does deal with water and battery changes better.<br><br>Also, check out the flashlight discussion forums at:<br>www.candlepowerforums.com<br><br>-john
