Actually no, you just said "regarldess of distance", not mentioning any
maximum distance at all. How would you define "the maximum distance the
light source would have an effect from"? Using the ADC-bailout threshold? Or
floating point precision error threshold? Or...? It's not at all clear what
you're talking about.
