I recently buy a couple of these to put in we card . but I also have a few of the old AA Maglite flashlight around and decide to upgrade they with the TERRALUX LUXEON EXTREME p-4 tle-5ex upgrade kit simply because I like the way they have be customize with the rear on off button and rubber lens hood . well I be a little surprised that when the new aa lead mag 's arrive I notice that they be considerably larger than the old version , and the light produce be ok , but not great when compare to the TERRALUX LUXEON upgrade . the 3 aaa be a much brighter flashlight but be almost the size of a 3 c cell flashlight that I also convert but in this case I use the maglite 3 d\/c cell lead upgrade . this be a huge improvement over the 3 aa flashlight as you might imagine , and much brighter than any standard maglite . but back to this flashlight . I will keep the two lead aa flashlight I have , since they be nice , and the candle option be pretty impressive . but the Terralux Extreme p4 aa tle-5ex be amazingly bright and I love to use the rear button upgrade -lrb- that really make this a great flashlight -rrb- plus the other upgrade I have buy for my old AA Mini Mags . I can not tell you how much more light the tle-5ex upgrade be over a new AA LED Maglite , but it have to be at least 100 time better , no kidding . SO rather than buy a new AA Maglite LED , I would suggest that you just upgrade you current flashlight with the tle-5ex , and I honestly believe you will be much happier go this route . this upgrade retain the focus ability of the minus mag , and cost less than buy one of the new Mini-Mag AA flashlight . on the other hand the new minus mag be a very nice flashlight , and the over all construction be better than the old incandescent mini-mag .
