I'm working on a project right now that has some very low power consumption requirements. I had originally planned to use ~20 ma LED's, but now it looks like my only option is the ~350 ma variety. I was thinking I could perhaps pulse them at a very high frequency using a 5% duty cycle, but I'm just not sure that they would still be visible. Could that possibly work, or maybe there's some other way that would draw an equivalent amount of power?
