im trying to identify some cree leds different red ones , is this possible using a led battery tester or even a multi meter i need to find the 660nm ones from a bunch of mixed up ones some are 625nm and some are far reds all cree though . or is there any identifying marks on them to look for ?
do they look brighter or less bright depending on nm ?
