I got my dad an ultracapacitor flashlight (http://www.ohgizmo.com/2008/11/10/ultracapacitor-flashlight-recharges-in-90-seconds/ http://www.ohgizmo.com/2008/11/10/ultracapacitor-flashlight-...) a few years back and he loved it till it got stolen. Really quick recharge time, decent "battery" life. Interestingly this flashlight was discontinued, and I don't see any new ones on 5.11 tactical's website. I wonder why? I'm really interested in any increases in these types of technology, love to see what comes of this.
