I have a couple of white LED flashlights.  The light is very soft, very
bright but very blue/white.  Been thinking of adding some ambers to warm
up the color.  Saving burned out incandescents to salvage the bases,
adding a printed circuit board mount and series connecting the LEDs.  I
was planning on using 4, as 12 volt charging voltage is closer to 14
volts.

Will be interested in hearing about your results.  My project list is
still not down as far as LED experiments.

Used same batteries for three weeks (3 x AA) after leaving flashlight
burning at work over a weekend.  That's in a 2 LED torch.
