    So while the one may be brighter, it's only brighter in the middle, it's got a bit more focus...if that makes any sense...
    Sure does. My point is that if you are using an LED as an indicator, 20-25mA is plenty to get a sufficiently bright display with the right LED. A high efficiency LED at just 1mA can be almost blindingly bright.

    Absolutely TRUE!

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Agreed. It is just an indicator.
