Probably parallel strings of LEDs.

*Series* strings. Parallel does nothing but cause more trouble. ;-)


I meant several series strings -in parallel-.

curiously,some free Harbor Freight 9 LED flashlights I have have all 9
LED's in parallel,and no current limiting resistor,depending instead on the
internal resistance of the 3 AAA cells.
