    Not that I am aware of. However, in the US ANSI puts out a standard for
    optical com with LED sources. Of course this doesn't include white.
    You might want to look into it though.

    Good luck,

    Yes, there is.

    See in particular part 9 of the standard. Essentially, you must calculate
    the amount of radiation incident on the eye, and then compare this to the
    MPE. This requires some knowledge of the beam pattern for the LED; some
    manufacturers supply this info, for others you'll have to measure it.
