    As cheap as they can be.
    Very bright.
    All of them work!


    None really.


    I have burned one "accidentally" by direct driving it from a Li-Ion battery.

    It was 3.7V and current was 110mA, it burned in like 5 - 10 seconds; so don't do it :)


    Build nice constant current circuit for them (or just use resistor if you are cheap and/or like simple solutions) and they won't fail you. I think you should drive them @ 20mA for safe operations without burning them out (didn't try yet, but i think it would be something like 3.4V for that purpose).

    IF you are willing to risk of killing them, use max 40mA, no more!:)
