FWIW, the only reason I recommend the the use of resistors for voltage limiters is for most folks they just need a simple way to fire 4-6 LEDs reliably and easily enough to whip together in an hour or so without any real electronics knowledge. AND not have to pay commercial companies big bucks for a silly LED.
