Can use buck converter instead of resistor to set proper LED voltage?
nearly every basic circuit i've come across involves leds uses resistors lower voltage, typically 5v , higher, correct 1 each led, typically 1.8-3.0v, don't burn out or die prematurely. perhaps more advanced circuits use voltage regulators. both waste energy heat, inefficient.
so wondering if it's possible , advisable use small buck converter, uses more efficient switching circuitry, bring higher voltage down led's proper voltage level, less energy wasted. seem useful in remote device runs on batteries or solar/wind, standalone indoor night light or outdoor security light.
if answer yes, boost converters, can use single aa or aaa battery, or 1.5v coin or button battery?

it's not voltage needs controlling current, have led gives proper brightness 15 ma flowing, constant current controller hold current @ 15 ma whatever voltage, long higher minimum required , lower maximum circuit tolerate.
