As you can see, after ~20 samples the Y values level off and are more-or-less
(range-bound), but the difference between the initial sample and stable samples
0.2%, which is a little more error than I'd like to see for this application,
So a few questions, I guess:
* I assume this is likely a heating-related effect, in that the illuminant
outputs more or less light depending on its temperature; is that reasonable
others' perspectives? Have others seen this same effect? Is it possible
else (firmware or software-related) is involved?
* Assuming that temperature-variable light output is the issue, I assume the
only way to
eliminate these effects is to 'warm up' the bulb by taking multiple
beginning to sample.
