warning : the review for this item be mixed between a few different item . some be lead bulb , some be krypton bulb . Below be my comparison of the two , and some other option available , but look carefully . Amazon , shame on you for mix two very different product on the same page , you be set yourself up for some unhappy customer . original review ... when I think it be the krypton bulb version ... . for a while , I have a few of these wonderful little light . in the day -lrb- the 90 's that be -rrb- they be ok for the size . sadly today they be vastly outclass by about anything with a decent led light in it . the 2xaa and 3xaa minus lead Maglites be my favorite flashlight , stylish , bright enough for general use , battery life be great , especially when you compare it to these older unit with the regular old krypton bulb in they , the LED one be worth the extra $ 10 . for $ 25 you can do better too . search out Nebo Redline and for $ 25 you can get 2x-3x the power in a similar pocket-able size , minus the belt holster . lead light be everywhere now , and sadly even the lead mini-maglite be a little behind the time . fwiw , the head and body of these be not the same as the lead version light , even the tail cap be different I think , so you can not use you old mini-maglite for part , but if you have a old one and want to perk it up , look up the Teralux lead conversion bulb , you 'll get about the same light from it as the Maglite version , but for the cost of the upgrade .
