Heat? You worry about heat in a low power device? You worry about wasted
power when referring to milliamps?

I am not even the one you are talking to, and you are pissing me off
with your holier than thou attitude.

Let it go. If this is where you come to boost your self esteem, you have
personal  issues to work out.

Lots of us know a hell of a lot more about electronics than you, but so
what? The man just wanted some ideas about how to hook up some LEDs. Go
find some placed else to brag about your skillset.
