store retail price can go as low as 3.5$
and go as high as 6$.(got one for 3.5:money_mouth_face:
set includes this fake 18650 3800mah cell
( rated at 800mah) and charger adapter
the flashlight also acts as a charging device
for the 18650 battery. the charger is rated
at 4.2 v so no special circuit required inside
the light.
Upon reading the voltage output, it is
higher than the specified 4.2v rating(gulp)
the charger has a green indicator to show
full charge. battery voltage is exactly 4.2v.
still have to verify if charger cuts of at green
light or continues charging ( would be ok
if charger outputs less than 4.2v)
the light uses an xpe-r3 led and a combination of orange peel, shiny
reflector.
beamshots:
due to iphone with no manual settings, I
really cant quantify the brightness of
the light. you can see 3 rings on the
beam due to dual reflector design. when
you focus the beam further, the middle ring
is not noticeable.
if you compare the high and low beams, they
do look the same in the pic but the low beam has visible pwm.
since i have no sphere and lux meter, i can
only give you tail cap measurements. you
can base the lumens on that value.
i have no runtime graph though, can you
recommend a method to measure runtime?
overall, this flashlight is of great value but
the high charging voltage might make it
a potential pipebomb. do you have any recommendations on modding this charger
to give lower voltage?
thats all folks, thank you!
