Grumpy_Mike:
The other thing you missed is that you keep saying mAh.mAh - stands for milliamp hours
Of course. I'm much more involved with mAh batteries and A (not mA) devices, so when I typed mA the 'h' got hit by habit.
Also the mA DOES NOT vary with colour, it is the forward volt drop that varies with colour.
I'll look again for that chart. It gave specs for voltage drop and mA according to color. Not cast in stone because every manufacturer is different, these were more relative averages, but still a good reference. (My bookmarks got wiped out accidentally while scrubbing a malware.)
Wow found it! Technical LED Color Chart I misremembered it slightly - the '50 mA' values were for the infrared and 'ultra' red LEDs. Everything else is referenced by -mcd- @20 mA. The cool part is that it shows how Vf -can- vary by almost 2x from 2.0 to 3.8 and that was the point of the descriptions about calculating R.
