How much power can these LEDs handle? Answered
I'm working on a project and I would like to connect two green LEDs two ultra bright Red LEDs and 2 blue LEDs. I got the green leds from radio shack so i know they need 2.1v dc, 25ma but the red ones and blue ones I got from some old toys so I don't know what they need. Any Ideas how much power I would need if I connected them in series? I have a bunch of old wall warts of varying sizes (9v 350ma, 9v 210ma, 5v 1a, 12v 750ma 12v 150ma) but only a few LEDs so I don't want to fry them and I don't need to push them to the limts. Here's some pics of my LEDs the small one is the blue one and the other clear one is Red.
