Hello!
I'm trying to decide on how to power just three 3.2V 20mA LEDs. I'd like to use a standard AC/DC adaptor that I can plug in to a mains socket at home. I've been reading quite a bit online (https://www.ledsupply.com/) to try to understand exactly what items I'll need. As far as I can tell I can either set up my configuration with:
1) an AC/DC power supply - LED driver - my LEDs
or
2) an AC/DC power supply - a resistor - my LEDs
I'd rather go with the second option as it seems as though it would be considerably cheaper but I'm having such a hard time finding an AC/DC power supply with an appropriately low output current & wattage that I suspect I may be misunderstanding something. Could any kind person help point me in the right direction?![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
