  1. The people selling these bulbs claim an efficiency of at least 3 times
    that of incandescent bulbs. This can't be true. Does anyone know the
    actual efficiency difference?

  2. On what basis do you make this assertion?


    Efficiency of incandescent bulbs is between 2% and 7% depending on how you
    calculate it,

    so 3x efficiency only needs to be 15%
