I have hear of MagLite for many year , but never actually own one -lrb- mainly because I be too cheap to pay $ 20 + for a flashlight -rrb- . when I find this new version of  maglite sp2201h 2-aa Mini lead flashlight  fortunately for I , this turn out to be a great purchase . about the LED : the light source be a Philips Luxeon rebel lead . it be call a ' 3w lead ' , but that be refer to its peak power . for steady-state operation the LED current be limit to 350ma , which mean it can only operate at about 1 watt -lrb- 350ma \* 3v -rrb- . if you ever try to run this led at 1000ma current -lrb- 1000ma \* 3v = 3w -rrb- , it could burn out within seconds . about the focus system : the beam be very bright -lrb- \* blindingly \* bright at short distance -rrb- but not quite focus . adjust the reflector can change the shape of the center bright spot slightly , but do not help much to focus it . about the power consumption : this flashlight use a internal regulator to run the lead on just two aa cell -lrb- unlike most cheap led flashlight which typically run on three aaa cell -rrb- . the light output be not constant when use alkaline -lrb- 1.5 v -rrb- or nimh -lrb- 1.25 v -rrb- cell . with two fresh alkaline cell , the battery current be about 500ma at 100 % power , 125ma at 25 % power . when the battery voltage drop below 2.5 v approximately , the input power be reduce to conserve energy -lrb- see the customer image section for my chart of `` Input Power vs. Battery Voltage '' -rrb- . this be much better than simply drop dead without warn , as some people have complain in older review -lrb- \* -rrb- . about the instruction -lrb- or the lack of it -rrb- : the maglite I receive say `` NEW Multi-Mode Electronic switch '' on the package -lrb- \* -rrb- . it further claim the flashlight can operate in four different mode -lrb- 100 % power \/ 25 % power \/ Blink \/ S.O.S. -rrb- however , there be absolutely no instruction on how to activate this `` electronic switch '' . after many attemot , I suspect that my unit must be defective , and be about to return it . but in the process of measure the battery current -lrb- which make and break contact with battery -rrb- , the led start blinking ! it finally dawn upon I that the on-off switch be also use to activate different mode : - when the flashlight be first turn on , it start in 100 % power mode - if you turn off the flashlight and turn it back on within 1-2 seconds , it advance to 25 % power mode . - follow short off\/on sequence advance it to ` blink ' mode and then be . O. S ' -lrb- ... -- ... -rrb- mode . - if you turn off the flashlight and wait at least 3 seconds before turn it back on , it start in 100 % power mode again . overall , I be very impress by this minus lead flashlight . but I can not help wonder : how many of they get return because people can not figure out how to activate its other mode ? -lrb- \* -rrb- footnote : the energy-management and multi-mode led function be new feature of this maglite . that be why they be not mention by older review write more than 6 month ago .
