I have be a fan of maglite product for year . it be the quality of the machine aluminium case . I have be think about upgrade some of my maglite to lead when this aa lead MAGLITE become available . it be slightly longer than the non LED AA MAGLITE . the led be much brighter than the incandescent version and have much whiter light . in fact it be so bright in comparison that I think a 25 % power mode or even variable power would be a good idea . it do not focus as well as the incandescent maglite but it be still much brighter so this be not really a issue . I think this product be extremely good value for the level of light output . I believe a led conversion kit of similar quality would cost about as much . you can drop it and it still work . I have drop mine twice by accident with no ill effect . I think MAGLITE have do a good job with lead technology . the LED AA MAGLITE be a big advance over the incandescent version and easily worth the extra money . there be also a 3xaa version which I be tell be much brighter . I want one to keep in my pocket so I prefer the shorter version . the 3xaa may suite other people better .
