Sorry if I expressed myself wrong :? I didn't want to ask about the avaliable packages of LEDs.I wanted to ask if a SMD LED will drop more voltage (or less). In another words: How much drop do you think will force a blue SMD LED? Thank you! :roll:
I can writing about this blue PLCC LED in my hand: 3.7V if the current is 15mA. I'm sure,the voltage depend only from wawelength (colour) and maybe manufacturer (type) but not from packaging.
Bogdan, my white LED 4.2V if the current is 50mA. I've not forgotten the PSU...
