White LEDs use a phosphor to kick blue light into a broadband emission. Most phosphors glow for a period after the excitation ends, and for 99.999999% of users thats just fine, but not in a strobe. A "pure" red or blue LED will go off when you tell it to, because the light is only emitted from the diode junction when current flows.
