I use a set of AAA Eneloops in my headlamp at work; they last a full week of working nights, with very little output drop-off until they’re almost dead.  
CandlePowerForums has a [forum](http://www.candlepowerforums.com/vb/forumdisplay.php?9-Flashlight-Electronics-Batteries-Included) with loads of info about Eneloops (and other batteries); the signal/noise ratio isn’t the greatest, but it’s not _“find the needle in the haystack”_ bad.
